In this paper, an improved and yet simple processing sequence for highly efficient MIS-contacted diffused n/sup +/p junction (MIS-n/sup +/p) silicon solar cells is presented. The process is characterised by: (i) formation of a metal-insulator-semiconductor (MIS) contact on an n/sup +/-diffused emitter; (ii) aluminium metallisation for front and rear electrodes; and (iii) low-temperature surface passivation by PECVD silicon nitride. For MIS-n/sup +/p solar cells with the front grid defined by Al evaporation through a shadow mask, efficiencies of up to 20.6% have been obtained. Furthermore, mask-free metallised cells with a mechanically grooved front surface have been fabricated. These cells have reached a confirmed efficiency of 21.1%, the highest value to date reported for MIS-n/sup +/p silicon solar cells.","PeriodicalId":251166,"journal":{"name":"Conference Record of the Twenty Sixth IEEE Photovoltaic Specialists Conference - 1997","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124677017","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}

After growing the CuInSe/sub 2/ film, the film surface was quickly converted to a possible ordered vacancy compound (CuIn/sub 3/Se/sub 5/). AES depth analysis indicated the presence of a CuIn/sub 3/Se/sub 5/ layer on the CuInSe/sub 2/ surface. The energy bandgap shifted from 1.04 to 1.24 eV by the formation of CuIn/sub 3/Se/sub 5/ phase on CuInSe/sub 2/ surface. Because the lattice parameters of CuIn/sub 3/Se/sub 5/ are smaller, the XRD peaks were shifted to higher 2/spl theta/ values. In/sub 2/Se/sub 3//CuInSe/sub 2/ cells with a thin CuIn/sub 3/Se/sub 5/ layer at the interface yielded solar efficiency of 8.46% with an active area of 0.2 cm/sup 2/.

Contacts are sandwiched between a supportive silicon substrate and a 40 /spl mu/m thick active silicon device layer.

The cell is very simple to fabricate and, in principle, its color can be tuned through the visible spectrum, ranging from being completely transparent to black opaque by changing the absorption characteristics of the dye.
