This research discusses the different methods applied during experimentation allowing for the reach of higher efficiency, explaining the effects each method had on the different samples used. Some of the methods to be discussed are some conventional methods in the creation of perovskite solar cells such as sonication, spin spin-on doping, annealing, and contact creation. In accordance to the methods used, a power conversion efficiency of 15.2% was obtained, as well as an open circuit voltage (Voc) of 1.065 V, a short circuit current (Isc) of 1.99 mA, a fill factor (FF) of 50.4%, a short circuit current density (Jsc) of 28.2 mA/cm2, and a shunt resistance of 3.3 kΩ. Each sample is discussed in order to provide a wider view on the positive and negative aspects of each method applied.","PeriodicalId":6749,"journal":{"name":"2019 IEEE 46th Photovoltaic Specialists Conference (PVSC)","volume":"115 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":"89106524","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}

At very low Boron concentration, bulk resistivity values ≫100 Ω-cm are achieved and an effective lifetime above 1 ms is measured, corresponding to an estimated bulk lifetime around 2 ms. In contrast to ingot-based wafers, continuous growth using Direct Wafer technology produces a very tight resistivity distribution at any desired target resistivity, without variations caused by zone refining. In addition, the technology enables growth of 3D wafers, e.g. thin wafers with a thick frame that allows to maintain mechanical wafer strength. Thus, Direct Wafer product can be customized for a given solar cell architecture by growing each individual wafer at the optimum bulk resistivity and optimum thickness.","PeriodicalId":6749,"journal":{"name":"2019 IEEE 46th Photovoltaic Specialists Conference (PVSC)","volume":"14 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":"87473640","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}

When photovoltaic (PV) generation approaches the mid-day electric load demand, actions must be taken to balance the supply and demand. The challenge of matching the generation and demand is expected to vary with location. The goal of this project is to estimate the amount of PV that Regional Transmission Organizations (RTO) in the United States can afford to have on its grid before solar curtailment, storage, or load shifting will become important at mid-day to maintain balance of supply and demand. This paper uses historical renewable generation and load data for each RTO to assess imbalance between electricity supply and demand as solar generation increases. Imbalance was estimated as a function of solar penetration. Two scenarios were used to model the imbalance: 1) when the net load is calculated to be negative (PV generation exceeds the demand); and 2) when net load is less than a minimum generation limit value, e.g., determined by policy for baseload generation from conventional sources. The impact of increasing solar generation on real-time pricing is studied for the case of California, which presently has the highest solar penetration of the U.S. RTOs. This paper thus provides data-based projections for U.S. RTOs on the degree to which storage, load shifting, or trading on energy imbalance markets will need to be adopted to avoid severe curtailment of solar PV electricity generation.","PeriodicalId":6749,"journal":{"name":"2019 IEEE 46th Photovoltaic Specialists Conference (PVSC)","volume":"25 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":"75469729","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}

Moreover, a maximum efficiency of 17.8% ha has been achieved with steep Ga grading. Here, a first step to the establishment of a growth model of CIGS grown at low temperature is proposed by coupling surface and volume characterization.

Here, CdTe thin films with a range of grain sized were produced by varying the CdC12 post-deposition treatment temperature. We use high-resolution cathodoluminescence (CL) microscopy to study recombination and shallow defect levels in detail. Intensities from room temperature CL maps were compared across samples. We find that the CL intensity initially increases with grain size, as expected, but then plateaus as the grain size is increased further. The plateau is correlated with a decrease in the characteristic length-related to the carrier diffusion length-determined from CL intensity profiles near grain boundaries. In addition, low-temperature CL measurements demonstrate the evolution of the defect levels with CdC12 temperature.","PeriodicalId":6749,"journal":{"name":"2019 IEEE 46th Photovoltaic Specialists Conference (PVSC)","volume":"61 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":"80104628","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}
