The capability allows for progressive failure monitoring during accelerated ageing with dynamic control of the characterization environment (e.g. imaging at specific temperatures and mechanical stress levels). Both light and dark IV curve tracing are implemented with techniques to overcome light and temperature instability inherent to the chamber. A Raspberry Pi-connected camera with infra-red filter removed is used for EL imaging, providing a low-cost, small form-factor solution which is desirable for use in a harsh environment. The camera is installed within a thermally-isolated housing mounted within the climate chamber. Measurement and control are achieved via LabVIEW, where characterization is integrated as part of the test protocol and performed automatically.","PeriodicalId":6749,"journal":{"name":"2019 IEEE 46th Photovoltaic Specialists Conference (PVSC)","volume":"1 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2019-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79916484","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}

Because the minority carrier diffusion length (L) is a factor determining the solar cell performance and L changes due to radiation damage, it is important to predict the detector performance based on the relationship between L and the absorbed dose. In this study, the effect of L on a radiation-induced current as a dose signal in InGaP solar cell is clarified by irradiation tests and empirical calculations. In order to estimate the L for InGaP solar cell, measuring the short-circuit current density (JSC) as a function of γ-ray dose rate is conducted. Based on the experimental results and the empirical formula of the relationship between L and JSC, the operational lifetime of the InGaP solar cell detector under various dose rate is estimated and is determined by the cumulative dose. The present result suggests the InGaP solar cell has high potential as a radiation resistant dosimeter for contributing to the decommissioning of the Fukushima Daiichi nuclear power plant.","PeriodicalId":6749,"journal":{"name":"2019 IEEE 46th Photovoltaic Specialists Conference (PVSC)","volume":"118 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2019-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77294065","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}

We report the results of coupled optoelectronic device physics simulations of GaAs nanowire homojunction solar cells and GaAs nanocone heterojunction solar cells where SnO2 and CuSCN are used for charge carrier collection. Our simulations include realistic recombination models for bulk and surface recombination. We find the optimal design is a radial junction with moderately p-type GaAs.

The work presented here is a fully scoped proof-of-concept demonstrated on a year of spectral data clustered and analyzed for every month of 2017 in Boulder, Colorado. Preliminary results demonstrate a decrease in 5 percent relative error in energy yield predictions between one standard testing condition and up to seven clusters found with this method.

This paper focuses on photovoltaic electrodialysis (PV-ED) desalination and proposes novel, flexible operation modes to integrate more efficiently the time-dependent solar power with the ED load, and replace energy storage in batteries by water storage in tanks. By first defining an irradiance-dependent desalination schedule, and further on extending the system flexibility to adjust in real-time the system power consumption, a better matching between the energy supply and demand is proposed that directly converts solar energy into water and potentially eliminates battery needs. Coupled with a system-level optimization of the desalination and power modules, operating with a flexible schedule leads 42% capital cost reduction compared to PV-ED systems conventionally designed. Additional cost reductions are anticipated from the fully-flexible operation with close to 90% of the solar energy directly used by the system, which is twice as much as the level achieved by binary on/off control in the optimal configuration.","PeriodicalId":6749,"journal":{"name":"2019 IEEE 46th Photovoltaic Specialists Conference (PVSC)","volume":"232 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2019-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76221765","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}

International standards for reference cell calibrations require that reported reference cell response (typically Isc) vs. total irradiance must be linear. How can linearity be efficiently determined? In 2006 NREL developed a test bed, based on the \"two-lamp method\" that provided a low cost, but low accuracy method for determining whether cell response was linear with irradiance. This paper describes very simple changes to NREL's historical method [1] for determining linearity that yield greatly improved results.
