The paper describes the calculation method, using operational data from the system, and discusses the implications for the design of BIPV systems in urban areas where partial shading is likely.","PeriodicalId":251166,"journal":{"name":"Conference Record of the Twenty Sixth IEEE Photovoltaic Specialists Conference - 1997","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124262896","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}

Promising near term thin-film candidates are amorphous silicon (a-Si), cadmium telluride (CdTe), and copper indium gallium diselenide (CIGS). The authors discuss the modifications that are necessary to adapt terrestrial thin-film technology for use in space. They characterize expected module performance and present results of tests performed on sample cells. They consider the possibility of achieving aggressive cost, weight and performance targets through the use of thin-film photovoltaic (PV) technology.","PeriodicalId":251166,"journal":{"name":"Conference Record of the Twenty Sixth IEEE Photovoltaic Specialists Conference - 1997","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126751769","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 interaction between the CBD and the CIS has been investigated and the results show that Cd might be instrumental in shaping the interface. We have also developed a process to fabricate a 13.5% efficiency ZnO/CulnGaSe/sub 2/ device without CdS or other buffer layers.","PeriodicalId":251166,"journal":{"name":"Conference Record of the Twenty Sixth IEEE Photovoltaic Specialists Conference - 1997","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133797970","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 most critical need for rural electrification exists in northern and western China, where 80 million people had no access to grid electricity at the end of 1995. In February 1995, the US Department of Energy signed an Energy Efficiency and Renewable Energy Protocol Agreement with the Chinese State Science and Technology Commission in Beijing. Under this agreement, NREL is providing assistance to several central government and provincial government agencies in China to develop photovoltaic and photovoltaic hybrid applications for rural electrification.","PeriodicalId":251166,"journal":{"name":"Conference Record of the Twenty Sixth IEEE Photovoltaic Specialists Conference - 1997","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125475748","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 encapsulation consisted of high quality SiO/sub 2/ and SiN/sub x/ layers deposited by plasma enhanced chemical vapor deposition (PECVD). The mechanical stability of such SiO/sub 2/ and SiN/sub x/ layer systems as well as the diffusion of electrically active impurities out of the substrate through these layers were investigated. A newly designed moveable large area heater (LAH) with halogen lamps mounted perpendicular to the scanning direction was used to recrystallize thin Si layers deposited on various mc- and ribbon-Si substrates covered with perforated SiO/sub 2/ intermediate layers. An algorithm to detect the melting point automatically was developed and homogeneous recrystallization out of these seeding holes could be achieved.","PeriodicalId":251166,"journal":{"name":"Conference Record of the Twenty Sixth IEEE Photovoltaic Specialists Conference - 1997","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127918956","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 system will be used to offset peak demand and serve as an emergency power system for YPG's water treatment plant. The power station includes 450-kWp of Siemens M-55 modules, 5600-kWh of C&D motive power batteries, and a 900-kVA power processing and control system from Trace Technologies. Enhanced by the battery load leveling system, the power station has the capacity to reliably provide from 450- up to 825-kVA to YPG's utility grid during the summer peak demand season. The YPG system has three basic operating modes: (1) daytime utility-tied, (2) night-time utility-tied, and (3) stand-alone. The amount of power delivered to the grid is governed by either available power from the PV array or by a power level defined by the user, whichever is greater.","PeriodicalId":251166,"journal":{"name":"Conference Record of the Twenty Sixth IEEE Photovoltaic Specialists Conference - 1997","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133165132","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}

Different crystallization morphologies-single crystal, columnar multicrystal or dendritic-are discussed in their dependence on the process and nucleation conditions.

Extracts were chemically analyzed by GCIR (gas chromatography infrared-ray spectroscopic analysis), GC-AED (gas chromatography atomic emission detector), and FDMS (field desorption mass spectroscopy). The conditions of this accelerated test were based on JIS-K9117. The analysis results showed that 2,6 di-t-butyl-4-methyl phenol of antioxidant and 2-hydroxy-4-octoxy-benzophenone of UV absorbent were consumed after the weathering test and that 3,5-di-t-butyl-4-hydroxybenzaldehyde having yellow color was newly produced.
