A study of improvements in silicon solar cell efficiency due to various geometrical and doping modifications

P. M. Dunbar, John R. Hauser

Open publisher page 0 citations

Abstract

This paper presents the results of continued studies of silicon solar cell operation and limitations. The objective of this paper is to report on geometrical and doping changes in silicon solar cells which result in predictions of high efficiencies. Efficiencies as high as 20 per cent (uncorrected for metal coverage and ohmic sheet resistance) have been calculated for optimized cells. The conditions required to achieve these efficiency values are discussed.
