To address this question one must consider the maturity of the technology, investment amount, derived revenue stream and overall risk. These factors can then be compared to conventional investment vehicles. A retirement investment vehicle should be capable of providing an income stream, which keeps pace with inflation for an indefinite period. This paper will provide actual financial performance data from a 6 KW DC/5 KW AC residential photovoltaic system with the performance of conventional retirement investment vehicles. The methodology for performing the economic analysis along with tax implications for each investment vehicle is presented. This will allow individuals to determine if a residential photovoltaic system should be considered as investment vehicle for retirement planning","PeriodicalId":344296,"journal":{"name":"2006 IEEE 4th World Conference on Photovoltaic Energy Conference","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127295477","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}

Due to the high-conductivity buried front contact, the metallization pattern may be readily adapted to handle the larger current densities produced at higher concentrations whilst minimizing shading. In the 1990's an efficiency of 18% at 30X concentration without prismatic covers was demonstrated in the EUCLIDES concentrator system. A matrix of cell process conditions has been investigated in order to optimize the emitter and front contact design of the LGBC cell for concentration factors of 50-100X. Efficiencies over 18% at 50X concentration have been measured on 2.56 cm2 cells.

Main issues are the sensitivity of cells to reverse bias application and their particular behaviour under reverse conditions (interaction between illumination and junction biasing). These matters impose a strong and reliable protection for every solar cell that can be implemented by means of integral diode concept. In the recent past, few diode anomalous behaviours have been detected during long duration high temperature testing: they were caused by marginal design but also by external causes like voltage and current spikes, not really representative of in-orbit conditions. Starting from these \"negative\" experiences, we first improved the integral diode design and then we verified by means of a comprehensive campaign all the major technical issues: on-ground and in-orbit spike environment, component rating with respect to the diode, solar cell electrical characteristics were therefore investigated and a qualification plan based on this approach was established covering all the aspects. This paper presents the diode lifetime analysis focused on spikes generator, the derating rules and finally describes all the characterization and testing activities performed for qualifying the integral by-pass device","PeriodicalId":344296,"journal":{"name":"2006 IEEE 4th World Conference on Photovoltaic Energy Conference","volume":"457 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115395071","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 compositional depth profile was characterized by grazing incidence X-ray diffraction and Auger electron spectroscopy with Ar sputtering. The composition ratio [S]/[S+Se] in the films depends on the process and the composition ratio [Cu]/[In+Ga] during deposition.

Data are presented from large installations, allowing accurate estimation of failure rates and distributions of failure modes. Improvement in product quality is also described; we show that recent thin-film products can meet industry expectations for consistent power output. In addition, results of product characterization performed at First Solar are presented. Dependence of module output on irradiance and temperature is illustrated, and we show that common assumptions about such dependence (based on experience with conventional PV technology) may not hold for thin-film modules. Predicted behavior of module output (as computed with PV system modeling software) and real-world data are compared.

The maximum efficiency of a fluorescent collector corresponds to the Shockley-Queisser limit for a non-concentrating solar cell with a single band gap energy. To achieve this efficiency, the collector requires a photonic structure at its surface that acts as an omnidirectional spectral band stop filter. We find also a high potential of such photonic structures for the improvement of less ideal collector systems involving non-radiative recombination. Analysis of a fluorescent collector system by spatially resolved light induced current measurements and by quantum efficiency analysis shows that the collection efficiency of a real fluorescent collector system increases by up to 30 % with the help of a Bragg stack on top of the collector acting as a band stop filter","PeriodicalId":344296,"journal":{"name":"2006 IEEE 4th World Conference on Photovoltaic Energy Conference","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127283516","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}
