Especially the annealing behaviour of the open-circuit voltage Voc of n-doped amorphous silicon carbide heterojunction emitter solar cells is investigated in detail. We present our results of a significant open-circuit voltage improvement of more than 100 mV on both a flat and a textured front surface triggered by thermal annealing on a hot plate. The observed open-circuit voltage behaviour can be described best by a stretched exponential function, which in general describes relaxation rates in complex systems. Further we investigated the optimum conditions of a post deposition annealing step in order to reach the highest efficiency. During this analysis we also observed deterioration in solar cell performance when the structure is annealed for a very long time. In conclusion, we suppose that a diffusion of weakly bonded or free hydrogen, activated by the annealing which saturates dangling bonds in the amorphous layer itself and most likely more important at the heterojunction interface, is responsible for the strong improvement in Voc and efficiency.","PeriodicalId":411472,"journal":{"name":"2009 34th IEEE Photovoltaic Specialists Conference (PVSC)","volume":"183 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121935690","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 SCM measurements revealed highly nonuniform carrier depletions among the GBs, indicating the variety of electrical properties due to the specific GB structures. The EBSD measurement showed that the films are weakly [001]-oriented with small fractions of grains in the [111] and [110] orientations. Comparison of the SCM and EBSD measurements taken on the same film area led to the following observations: (1) Σ3 GBs do not exhibit carrier depletions and thus do not have charged deep levels; (2) Some Σ9 GBs exhibit carrier depletions and some do not, indicating that the intrinsic ਺9 GBs do not have charged deep levels and the carrier depletions are due to impurity gettering at the GBs; (3) No significant relationship between the carrier depletion behavior and the grain misorientation was found so far on the GBs with random misorientations; (4) The carrier depletion behavior does not depend only on the grain misorientation but also on the facet where the GB is taken.","PeriodicalId":411472,"journal":{"name":"2009 34th IEEE Photovoltaic Specialists Conference (PVSC)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122226505","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}

Over the last 7 years, Solar Systems has deployed 47 dish units, of which 23 are with multijunction solar cells, in five different commercial CPV power plants and two testing facilities, for a total installed capacity of 1.5 MWp. Recently, Solar Systems has designed and built a 140kWp Heliostat Concentrator PV (HCPV) system at its new Testing and Training Facility in Bridgewater, Victoria. The demonstration of the performance of the HCPV system met all the specification targets. The system reached a power output of 140kW with a DC efficiency of 24% to 26% and an optical efficiency of 84%, measured on two different days, four months apart, around solar noon. This is the first utility-scale Heliostat CPV system ever built. It is also for Solar Systems the first demonstration of a new technology to be deployed in a large 154-MWp power plant in Northern Victoria.","PeriodicalId":411472,"journal":{"name":"2009 34th IEEE Photovoltaic Specialists Conference (PVSC)","volume":"84 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127979908","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 PV Incubator project receives funding from the U.S. Department of Energy (DOE), through the National Renewable Energy Laboratory (NREL), and funding opportunities are cyclical. The PV Incubator project targets small businesses that have demonstrated a proof-of-concept/process in a laboratory, but still need to overcome significant barriers before they can achieve commercialization. After 18 months of funding, a successful project is expected to be able to enter the market in the 2011 timeframe at a price point that enables electricity close to grid parity. Ten Incubator subcontractors were awarded in 2007 and participated in Stage-Gate reviews in the summer of 2008. Seven of these companies transitioned to Phase II of their two-phased subcontract based on the outcome of the Stage-Gate review. In addition, a second Incubator solicitation was issued in 2008. The six companies selected for the 2008 round of funding were awarded subcontracts in early 2009. This presentation overviews the PV Incubator project, gives a brief synopsis of the current subcontracts and their accomplishments, addresses progress by subcontracts awarded under the Fiscal Year (FY) 2007 solicitation, and discusses new funding opportunities.","PeriodicalId":411472,"journal":{"name":"2009 34th IEEE Photovoltaic Specialists Conference (PVSC)","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115828153","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}
