We present preliminary work performed in the desert PV module project for the climate of Morocco as the base to guide the national market and contribute to the future of research and development applied to the industry. The purpose of this project is to develop a desert PV module adapted to arid and semi-arid climate of Morocco. Indeed, the started with an outdoor inspection of PV systems operating for more than three years in the climate of Morocco. For detailed inspection, we used advanced characterization techniques such as electroluminescence (EL), infrared (IR) imaging and I-V measurement. The general observation brings us to the severity of such climatic conditions on the durability of standard PV modules. This is noticeable not only at the level of the different aging mechanisms but also in terms of degradation rate values. The various degradation mechanisms are manifested by hotspots, cracks, encapsulants discolorations, potential induced degradation (PID), and delamination and snail tracks. In addition, degradation rates ranged from 2.02% up to 2.73%. Furthermore, we have proposed a new PV module design, based on the approach to mitigate the observed real aging mechanisms, the purpose of which is to save the life of the modules and improve their LCOE.","PeriodicalId":277228,"journal":{"name":"2020 2nd International Conference on Photovoltaic Science and Technologies (PVCon)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130470972","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the present work, Sb2Se3 absorber films were grown by radio-frequency (RF) magnetron sputtering technique using binary single target and employing various argon flow rates, and then they were annealed under argon atmosphere inside a tubular furnace. Sb2Se3 thin films were investigated using X-ray diffraction, scanning electron microscopy, energy dispersive X-ray spectroscopy, Raman spectroscopy, and UV-VIS NIR spectrophotometer. The effects of argon flow rate, one of the sputtering parameters, on the properties of the Sb2Se3 films were investigated. The significance of argon flow rate, that used during film deposition, on the observing of Se loss, antimony oxide formation and the change in the surface morphology was also addressed. We observed that the dominant crystal orientation varied with respect to argon flow rate. It was further detected that high argon flow rates cause the decomposition of Sb2Se3 structure and formation of antimony oxide phase. The overall analyses revealed that argon flow rate used while sputtering is effective in changing the structural, and optical properties of the Sb2Se3 thin films.","PeriodicalId":277228,"journal":{"name":"2020 2nd International Conference on Photovoltaic Science and Technologies (PVCon)","volume":"102 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123034400","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One mitigation technique is to optimize the interconnections between the PV elements to yield the highest energy harvest by finding the homogeneous cells. This paper presents results from an experimental study using a new experimental testbed that was developed to extract PV parameters in-situ. The experimental testbed is flexible, scalable, and suitable for the research and development of non-planar PV applications. The contribution of this paper is illustrating a framework to study PV interconnections and characterize PV parameters for non-planar PV systems using an in-situ experimental testbed.

Solar radiation data collecting from the ground-based meteorological station seems still the most reliable compared to others such as satellite databases. In literature, there is a number of recent studies that utilize directly old measure solar radiation data without any precaution. As a consequence, the solar system can be exposed to poor technoeconomic assessment. This paper attempts to find a close agreement to enhance the old measured data within the period 1971 and 2003 to make it more applicable for further studies and applications. Therefore, NASA POWER, PVGIS 5, Meteonorm software, and old measured data are used and compared to the new measured data (as reference). All measured data are collected from the World Radiation Data Centre (WRDC) published in various articles. Six distributed locations in the Asian continent are used as a case study for this paper. Statistical methods including Global Performance Indicator (GPI) are used to investigate and compare solar data sources. It is argued that the improvement of old measured data can be obtained either by the proposed method for each country or by a proposed hybrid of all solar data sources for any location in the Asian continent.","PeriodicalId":277228,"journal":{"name":"2020 2nd International Conference on Photovoltaic Science and Technologies (PVCon)","volume":"102 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116435648","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cost reduction of this technology could be obtained by promoting silicon –based tandem solar cells with low cost metal oxide materials. Cuprous oxide (Cu2O) is considered an attractive material for PV applications since it is a p-type semiconductor with high optical absorption and a direct bandgap of about 2.1 eV. The electrical and optical characteristics for aluminium doped ZnO (AZO) and undoped Cu2O thin film layers synthesized by magnetron sputtering were determined. A four-terminal AZO-Cu2O/ c-Si tandem heterojunction solar cell was investigated. I-V curve for the studied heterojunction tandem solar cell shows a rectifying behavior, but its stability and reproducibility has to be solved. Numerical modelling allowed to analyse the main electrical parameters of the two subcells, in order to maximize the performance of the solar device. The influence of the material characteristics of the buffer layer (electron mobility, buffer layer thickness and electron affinity) on the energy performance of the cell (η, FF, Jsc, VOC) was analyzed.The effect of interface defects on the electrical characteristics of the AZO/Cu2O heterojunction was evaluated. The defect analysis based on numerical modeling showed how the interface defects and band offsets of the considered Cu2O heterojunction tandem solar cell reduce top cell performance. The analysis suggested that the incorporation of a buffer layer could enhance the performance of the heterojunction solar cell.","PeriodicalId":277228,"journal":{"name":"2020 2nd International Conference on Photovoltaic Science and Technologies (PVCon)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131680082","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The silicon surface has either a wet chemically grown silicon oxide or the oxide stripped away by dipping into a hydrofluoric (HF) acid solution.

For HF-dipped samples, the J0s values are larger than 75 fA/cm2 and there is no clear dependency on plate temperature. Finally, we demonstrate the device performance using 2×2 cm2 silicon solar cells with double side pyramid texturing, phosphorus diffused front emitters and spray-coated PEDOT:PSS back contacts deposited on single side HF processed surfaces.

Therefore, an arc fault detector is essential to protect people’s lives and properties and is now required by many safety codes. Since an arc is a chaotic phenomenon, it is important to study the electrical characteristics in order to develop a robust arc fault detector. An automated mechatronics testbed was developed to allow highly repeatable testing needed to create a library of arc voltage and current waveforms. Electrode material and geometry, electrical voltage and current, and electrode gap separation profile were set as experimental parameters. These factors are hypothesized to affect the electrical characteristics and signature of the arc. In this paper, examples of data from the arc generation system are presented to showcase how the results of the parameter values can be compared. For each parameter value combination, or \"recipe,\" the paper will show how the testbed is used to capture and plot the arc voltage and current time-domain waveforms, the gap profile (separation distance vs. time), and the Short-Time Fourier Transform (STFT) of the measured electrical signals. The results of the analysis presented in this paper can be used in the development of a reliable and effective arc fault detector.","PeriodicalId":277228,"journal":{"name":"2020 2nd International Conference on Photovoltaic Science and Technologies (PVCon)","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116712184","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Both have oil-rich economies with low electrical utility prices, which render photovoltaic (PV) systems less financially attractive to consumers. However, a strong case can be made for for PV in oil-rich economies. First, energy generation from solar PV allows for higher profit gains of precious export commodities (oil and/or gas) instead of using them locally. Second, sunny weather conditions in most oil-rich countries, like Qatar, allow for more sustained and predictable PV generation with fewer interruptions. This paper presents a techno-economic study that explores the economic benefits associated with implementing a grid-connected rooftop photovoltaic and energy storage system (PV-ESS) in oil-based countries. Two case studies were used as examples of implementation in different parts of the world: Texas, USA, and Doha, Qatar. In both cases, a long-term simulation of a house with an installed PV-ESS system is used to determine the economic feasibility of residential PV. Factors like generation and load profiles, cost of grid consumption, cost of materials, and house size were considered in this study. Based on the study, house owners in Texas can breakeven their PV-ESS system cost, while in Qatar, this is more challenging. In addition to the techno-economic study results in this paper, the barriers-to-entry of solar PV in oil-rich countries are explored and discussed.","PeriodicalId":277228,"journal":{"name":"2020 2nd International Conference on Photovoltaic Science and Technologies (PVCon)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127913544","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
