A common optimization problem is the trade-off between fill factor and short-circuit current density when adjusting the carrier concentration of the TCO material. One way to circumvent this problem is to find high-mobility TCO materials and we contribute by performing a characterization of indium zinc oxide. We found that an optimum sample has a high-mobility of about 50 cm2/Vs with a sheet resistance of about 30- $40 Omega /mathrm {sq}$.

We demonstrate thinner cells are required to increase further the efficiency toward the intrinsic limit, as voltage increases and bulk lifetime dependence decreases.

The performance of the photovoltaic system depends upon various factors like type of solar PV technology used, irradiance, module temperature, wind speed, ambient temperature and other outdoor environmental conditions. The main objective of the study is to identify a suitable solar cell model for power prediction of a PV system for a location of interest and validate the results experimentally. A single diode model with 4 and 5-parameters is used for modeling of PV arrays. A hybrid approach of analytical and numerical methods has been utilized to identify the accurate parameters of solar cell model. The instantaneous output power is predicted by considering the effects of irradiance and module temperature on the power generation. The predicted power by both the 4 and 5-parameters models are compared and validated using an experimental PV system. The average percentage difference error between measured and predicted output power values for the 5-parameter model is 4.95% and 4-parameter model is 5.16%. The output power predicted using 5-parameter model is found to be much closer to measured values.","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":"1 1","pages":"0721-0726"},"PeriodicalIF":0.0,"publicationDate":"2018-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90172148","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}

We investigate semiconductor nanocrystal (NC) sensitized upconversion via triplet-triplet annihilation (TTA) in organic semiconductors (OSCs). Since this process relies on optically inactive triplet states in the OSCs, we utilize PbS NCs to directly sensitize the triplet state via energy transfer. This is possible due to the strong spin-orbit coupling in PbS NCs, resulting in rapid spin-dephasing of the exciton. Current technology allows for upconversion of light with a photon energy above $sim 1.1$ eV. However, while internal efficiencies are rapidly improving, the low external device efficiencies render them impractical for applications, as devices are based on a single monolayer of NCs. Our results show simply increasing the PbS NC film thickness does not show improvement in the efficiency due to poor exciton transport between PbS NCs. Here, we present a new strategy to increase the external upconversion efficiency by utilizing thin tinbased halide perovskites as the absorbing layer. Resonant energy transfer from the perovskite to the PbS NCs allows for subsequent sensitization of the triplet state in rubrene.","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":"38 1","pages":"3698-3702"},"PeriodicalIF":0.0,"publicationDate":"2018-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88463619","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, feasible reconfigurable module instantiations are selected given some design constraints. Then, the search space is further reduced by taking into account the typical operating conditions of the module. Finally, the best module layouts are chosen based on performance consideration.
