The effects of operational parameters such as deposition temperature, flow rate, reactant gas, and substrates properties, on the silicon film characteristics (deposition rate, grain sizes and preferred orientations) were extensively investigated. Surface morphology and minority-carrier lifetime of the deposited films were also studied. High deposition rates in the range 1-4 /spl mu/m/min were achieved on all types of substrates.

The analysis of the global solar radiation data (over 5 kWh/m/sup 2//day) has shown that photovoltaic systems can perform well all over the state, mainly in the north and northeast regions of the state. The potential for the utilisation of PV systems in Minas Gerais is large, mainly when considering the high number of consumers in rural remote areas that are not and cannot be supplied from CEMIG's grid in the immediate future or in the long term. As a consequence of the demonstration projects, which have shown that photovoltaics can perform well and be cost effective in rural areas, a Rural Electrification Program was launched. To support it a training program has been set up.","PeriodicalId":251166,"journal":{"name":"Conference Record of the Twenty Sixth IEEE Photovoltaic Specialists Conference - 1997","volume":"4 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":"125860204","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 MIM device consists of many individual InGaAs cells series-connected on a single semi-insulating InP substrate. An infrared (IR) back surface reflector (BSR), placed on the rear surface of the substrate, returns the unused portion of the TPV radiator output spectrum back to the radiator for recuperation, thereby providing for high system efficiencies. Also, the use of a BSR reduces the requirements imposed on a front surface interference filter and may lead to using only an anti-reflection coating. As a result, MIMs are exposed to the entire radiator output, and with increasing output power density. MIMs were fabricated with an active area of 0.9/spl times/1 cm, and with 15 cells monolithically connected in series. Both lattice-matched and lattice-mismatched InGaAs/InP devices were fabricated, with bandgaps of 0.74 and 0.55 eV, respectively. The 0.74 eV MIMs demonstrated an open-circuit voltage (Voc) of 6.16 V and a fill factor of 74.2% at a short-circuit current (Jsc) of 0.84 A/cm/sup 2/, under flashlamp testing. The 0.55 eV modules demonstrated a Voc of 4.85 V and a fill factor of 57.8% at a Jsc of 3.87 A/cm/sup 2/. The near IR reflectance (2-4 /spl mu/m) for both lattice-matched and lattice-mismatched structures was measured to be in the range of 80-85%. Latest electrical and optical performance results for these MIMs is presented.","PeriodicalId":251166,"journal":{"name":"Conference Record of the Twenty Sixth IEEE Photovoltaic Specialists Conference - 1997","volume":"517 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":"116235218","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}

First, their large area capability and the variety of possible substrate materials permit to apply a-Si:H PV modules directly on the surface of conventional heat collectors at low cost. Further, the low temperature coefficient of a-Si:H cells (0.1%/K) allows operation of a-Si:H solar modules at temperatures as high as 100/spl deg/C without substantial power loss. The authors focus on the thermal performance of such hybrid collectors based on a-Si:H cells, with emphasis on a ZnO coat on top of the solar cell. ZnO can be \"tuned\" to absorb the infrared part of sunlight and, at the same time, its emission coefficient for heat-radiation is nearly as low as that of the optimized selective surfaces used in thermal collectors. The authors propose a collector structure with a high potential for thermal conversion efficiency while maintaining high electrical conversion efficiency.","PeriodicalId":251166,"journal":{"name":"Conference Record of the Twenty Sixth IEEE Photovoltaic Specialists Conference - 1997","volume":"9 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":"121498762","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}

It is a widespread assumption that, owing to the largely 'open' rear surface, bifacial cells absorb less infrared (IR) light and hence operate at lower temperatures compared to monofacial cells. In order to verify this assumption, the IR light absorption properties of bifacial and monofacial silicon solar cells are investigated and the correlation with the temperature behavior of the cells is shown. Furthermore, the device regions leading to the absorption of IR light are identified and the reasons for the observed temperature differences of the cells under specific operating conditions are discussed.","PeriodicalId":251166,"journal":{"name":"Conference Record of the Twenty Sixth IEEE Photovoltaic Specialists Conference - 1997","volume":"106 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":"132213618","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}
