In the context of the French ANR research project IMPETUS, an innovative approach for III-V/Si multijunction solar cells is studied. The targeted device is a tandem cell composed of a III-V top cell (AlGaAs) and a IV bottom cell (Si1-xGex). The choice of AlyGa1-yAs as the top material is justified because it provides the optimum bandgap combination with Si1-xGex (1.63 eV/0.96 eV), with theoretical efficiencies in excess of 42% for such a tandem configuration. In our inverted metamorphic approach, we first use MOVPE to grow the AlGaAs top cell on a lattice matched GaAs substrate, and then perform low temperature PECVD heteroepitaxial SiGe on top. We show here the first structural and electrical characterizations of Si(PECVD)/III-V(MOVPE) interfaces. Furthermore, the epitaxial growth of highly doped crystalline Si by low-temperature PECVD on GaAs enables us to fabricate hybrid tunnel junctions with low resistivity and a high current, suitable to interconnect the two subcells in the tandem III-V/Si solar cell.","PeriodicalId":6524,"journal":{"name":"2016 IEEE 43rd Photovoltaic Specialists Conference (PVSC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76866348","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}

Space solar cells are becoming thinner for improved performance (W/kg) and are based on single crystalline materials where fracturing or cleaving can easily occur from packaging, deployment and constant temperature cycling in outer space. When the fracture in the semiconductor extends through the solar cell metallization, loss of power will occur and can hinder a mission. A novel semiconductor metallization is being developed that may enable the solar cells to be fully crack tolerant. The material consists of carbon nanotubes impregnated silver metallization, termed metal matrix composite, deposited by screen printing. The carbon nanotubes increase the fracture toughness of the metallization and also offers a redundant electrical path should the metal matrix fracture. In addition to these benefits, the use of screen printing will facilitate lower costs and ease of manufacturability by eliminating the expensive photolithography and evaporation steps used for conventional metallization. The inks that are being developed show promise of electrically bridging cracks and are further being tuned for screen printing processes.","PeriodicalId":6524,"journal":{"name":"2016 IEEE 43rd Photovoltaic Specialists Conference (PVSC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82718695","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}

Compared to the traditional stand-alone photovoltaic power system, this system shows the advantages of better protection and more efficient control on charge/discharge of the battery. Furthermore, it can make better use of solar energy and realize energy management of the system The key point of energy management for the system is to control the bi-directional converter efficiently, where bi-directional voltage and current must be controlled. In this paper, the control strategy of bi-directional converter is proposed, which operates at three operation modes: Buck (charge battery), Boost (discharge battery), and shut-down (SD). Maximum power point tracking control is used to extract the maximum power from the Photovoltaic array. Single power processing stage with multiple power ports offers an opportunity to make the whole system simpler, compact and more efficient. Finally, a simulation of 250 W and 5 hp converter is built to verify the theoretical analysis and the control strategies. The simulation is tested for variable irradiance and variable load.","PeriodicalId":6524,"journal":{"name":"2016 IEEE 43rd Photovoltaic Specialists Conference (PVSC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91080414","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}

In this study, a commercial PPE (polyethylene terephthalate (PET)/PET/ethylene vinyl acetate (EVA)) backsheet films was selected as a model system for a depth profiling study of chemical and mechanical properties of a backsheet film during UV exposure. Cryo-microtomy was used to obtain cross-sectional PPE samples. The NIST SPHERE (Simulated Photodegradation via High Energy Radiant Exposure) was used for the accelerated laboratory exposure of the materials with UV at 85°C and two relative humidities (RH) of 5 % (dry) and 60 % (wet). Chemical and mechanical depth profiling of the aged and unaged samples was conducted by Raman microscopic mapping, nanoindentation and atomic force microscopy in quantitative nanomechanical mapping mode. The results indicated that non-uniform degradation took place across the thickness of the PPE backsheet with severe chemical and mechanical degradation observed on the outer pigmented PET layer, two adhesive layers, and the pigmented-EVA layer. The regions with the increase in the modulus detected by nanoindetation were consistent with those showing clear chemical degradation in Raman and Attenuated Total Reflection Fourier Transform Infrared Spectroscopy (ATR-FTIR). This depth profiling study brings new understanding to the mechanisms of failures observed in the backsheets during weathering.","PeriodicalId":6524,"journal":{"name":"2016 IEEE 43rd Photovoltaic Specialists Conference (PVSC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84798215","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}
