Ingots were grown in ambients that ranged from pure argon (99.9995%) to pure N/sub 2/ (99.999%). /spl tau/ was measured as a function of position along the ingots using the ASTM F28-75 photoconductive decay (PCD) method. We found that Ga-doped, multicrystalline silicon ingot growth in a partial or total nitrogen ambient has a negligible effect on minority charge carrier lifetime and no significant grain boundary passivation effect. Values of 40 /spl mu/s</spl tau/<100 /spl mu/s were typical regardless of ambient. For dislocation-free (DF) growth, the degradation of /spl tau/ is minimal and /spl tau/ values above 1000 /spl mu/s are obtained if the amount of N/sub 2/ in the purge gas is below the level at which nitride compounds form in the melt and disrupt DF growth.","PeriodicalId":20517,"journal":{"name":"Proceedings of 1994 IEEE 1st World Conference on Photovoltaic Energy Conversion - WCPEC (A Joint Conference of PVSC, PVSEC and PSEC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1994-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74410955","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}

This necessitates a supporting substrate of a foreign material, with refractive index compatible with light trapping schemes for the silicon. The resulting inability to nucleate growth of crystalline silicon films of good crystallographic quality on such foreign substrates, prevents the achievement of high efficiency devices using conventional single junction solar cell structures. The parallel multijunction solar cell provides a new approach for achieving high efficiencies from very poor quality material, with near unity collection probabilities for all generated carriers achieved through appropriate junction spacing. Heavy doping is used to minimise the dark saturation current contribution from the layers, therefore allowing respectable voltages. The design strategy, corresponding advantages, theoretical predictions and experimental results are presented.","PeriodicalId":20517,"journal":{"name":"Proceedings of 1994 IEEE 1st World Conference on Photovoltaic Energy Conversion - WCPEC (A Joint Conference of PVSC, PVSEC and PSEC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1994-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84473832","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}

Large areas are available, since roofs and facades are perfectly suited for solar energy conversion. TALENTS ENERGY LTD has developed special PV-generators which fulfill at the same time the functions and requirements of conventional building elements. In the context of different R&D projects funded by the Swiss government to implement a series of typical building integrated photovoltaic systems, ATLANTIS ENERGY LTD was entrusted to design and build various hybrid building integrated PV-power plants. The following PV-building integrated systems are briefly discussed: the factory building 'Aerni' consisting of a 9 kW/sub el/ vertical PV-facade and of a hybrid 53 kW/sub el/ PV-system integrated into the skylights; the multifunctional PV-facade 'Scheidegger' with an installed peak power of 18 kW/sub el/; the hybrid PV-shingle roof 'Brig' with an installed peak power of 15 kW/sub el/ and 30 kW/sub th/; and the 8.4 kW/sub el/, 12 kW/sub th/ hybrid PV-shingle roof 'Rigi'.","PeriodicalId":20517,"journal":{"name":"Proceedings of 1994 IEEE 1st World Conference on Photovoltaic Energy Conversion - WCPEC (A Joint Conference of PVSC, PVSEC and PSEC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1994-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84567101","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}
