The technology is based on the direct integration of a multi-quantum well (MQW) modulating retroreflector (MRR) optical communication node and a monolithically integrated module (MIM) PV power source. The MQW MRR optical data link exploits the shift in the MQW absorption peak under an applied reverse bias to modulate incident laser light enabling binary encoding of data for transfer. A MIM consists of many individual solar cells monolithically integrated on a single substrate and offers the design versatility necessary to allow efficient electrical conversion of both incident sunlight and the system laser-light and the ability to match the voltage output to the MRR requirements. A description of the development of the MRR and MIM components of the system along with the power management and distribution circuitry is given. Results of bench-top demonstrations of the operational system are presented.","PeriodicalId":430266,"journal":{"name":"Conference Record of the Thirty-first IEEE Photovoltaic Specialists Conference, 2005.","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125207129","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}

Dual-junction cells with moderately lattice-mismatched (0.2% and 0.5%) structures have already reached electrical performance comparable to lattice-matched devices, at about 26% efficiency under AM0, 1-sun condition. Development efforts to date on highly lattice-mismatched (1.6% mismatch) structures have resulted in 22.6% efficiency dual-junction cells, with many improvements still possible. Spectral response measurements reveal excellent quantum efficiency (QE) for metamorphic GaInP and GaInAs materials, with a measured internal QE of over 90%. The offsets between the bandgap voltage (E/sub g//q) and the open-circuit voltage (V/sub OC/) of GaInP and GaInAs metamorphic cells were kept below 550 mV and 450 mV, respectively. Experimental results indicate that lattice-mismatched GalnP/GalnAs dual-junction cells can achieve higher energy conversion efficiency than lattice-matched GaInP/GaInAs dual-junction solar cells.","PeriodicalId":430266,"journal":{"name":"Conference Record of the Thirty-first IEEE Photovoltaic Specialists Conference, 2005.","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116803799","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}

Films have been characterized using atomic force microscopy, scanning electron microscopy, grazing incidence X-ray diffraction, photoluminescence, photoconductivity, and optical absorption. Both as-grown films and films processed by annealing using cadmium chloride (CdCl/sub 2/) exhibit promising properties for this use. As-grown films are crystalline, possess low surface roughness (4.4 nm RMS), small grain size (18 nm), large direct bandgap (2.54 eV) and are highly textured with some degree of hexagonal phase present. On annealing with CdCl/sub 2/ there is an increase in surface roughness (24.5 nm RMS), modest grain growth (23 nm), a decrease in bandgap (2.44 eV) and diffraction data are consistent with increasing hexagonal character. There is also evidence of better crystalline quality and a large reduction in electron trapping states upon CdCl/sub 2/ annealing.","PeriodicalId":430266,"journal":{"name":"Conference Record of the Thirty-first IEEE Photovoltaic Specialists Conference, 2005.","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121080940","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}
