The N+ layer is a transparent conductive oxide (TCO). The interface recombination rate between the p-GaSb and a-Si:H(i) layers is found to have an important effect on cell performance. If this recombination rate can be reduced to 105cm/s, the internal quantum efficiency in the wave range of 600 1700 nm surpasses 95% and the output power density reaches 2W/cm2 under a given blackbody radiation of 1500K. The high minority carrier electron mobility and diffusion length in the p-GaSb leads to the high internal quantum efficiency. A potential advantage of this cell is its simple cell fabrication process for low cost in high volume manufacturing. Another advantage for this cell for TPV systems is a built in short pass plasma filter with a high reflectivity at longer wavelengths.","PeriodicalId":6558,"journal":{"name":"2018 IEEE 7th World Conference on Photovoltaic Energy Conversion (WCPEC) (A Joint Conference of 45th IEEE PVSC, 28th PVSEC & 34th EU PVSEC)","volume":"16 1","pages":"0887-0890"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78008422","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}

For this end, we refit well-known models of numerical device simulations in order to acquire the uncertainties of the model parameters from the underlying measurement data. In a metamodeling and Monte Carlo simulation study, we then deduce how these propagate to the simulated solar cell efficiency. This is done for 150 $mu$ m thick 1 $Omega$ cm p-type standard and advanced silicon passivated emitter and rear cells (PERC) and for the limiting efficiency of silicon solar cells. We find uncertainties given by one standard deviation of 0.021%abs for usual PERC solar cells and 0.068%abs in case of the limiting efficiency. In a variance based sensitivity analysis, we find the uncertainties of the model parameters of the Auger recombination and the minority charge carrier mobility to contribute the most to the efficiency uncertainty. Besides these, we determine comparably large efficiency discrepancies of up to 0.6%abs for the two most prominent bandgap narrowing models, highlighting the necessity of further research on this topic.","PeriodicalId":6558,"journal":{"name":"2018 IEEE 7th World Conference on Photovoltaic Energy Conversion (WCPEC) (A Joint Conference of 45th IEEE PVSC, 28th PVSEC & 34th EU PVSEC)","volume":"3 1","pages":"2658-2662"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73180578","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}

An outlook on the BIPV market estimated the worldwide installed BIPV capacity during 2016 to nearly 2 GW, confirming the growing trend, increasing by 12.6% compared to 2015, when 1.78 GW were installed [2]. But the integration of BIPV is still going slow, which is unfortunate considering its potential. Despite technical promise, there is a notable disparity between the progress made in terms of the technology and the knowledge and skills of the professionals (architects, engineers, designers, planners) who are ultimately responsible for the integration of BIPV systems. This paper presents the results of the Dem4BIPV project, which has been designed to develop master-level courseware on BIPV for various European academic institutes. The structure of the lectures, the ideas behind practical assignments and on potential examquestions will be presented. Furthermore, a conceptualframework of the curriculum’s content will be presented.
