Original Paper


Due to in-situ deposition process doped SiOx material attracts the PV community as intermediate reflecting layer (IRL) for the less hazardous deposition process. Previously we have been shown that how to formulate a better quality SiOx layer using seeding technique. In this paper we have shown that how this superior quality material will be beneficial as IRL and improve the performance of micromorph solar cells. Enhanced performance is observed when SiOx material is deposited with the help of highly conducting seed layer. For improving the performance of the micromorph solar cell further we have eliminated the n-layer of the top constituent cell. In the context of substituting the top n-layer, SiOx layer grown on seed layer is more significant as of its suitable optoelectronics properties. Initial efficiency of ∼12% is perceived in micromorph solar cells with the improved SiOx based IRL used innovatively which is 7.9% higher than that of the cell with conventionally developed and typical use of IRL.
