ELECTRICAL-PROPERTIES OF THIN SILICON SPACE SOLAR-CELLS

Thin silicon solar cells with a Non-Reflective front Surface (NRS), a passivated rear surface and locally diffused BSF structure have been c onsidered to be hopeful candidates as space solar cells of the next ge neration. In this paper, the electrical properties of textured surface cells and flat (non-textured) surface cells are compared and the surf ace recombination velocity S-e of these cells are discussed. Then, the electrical properties of 10 Omega cm substrate cells and 2 Omega cm s ubstrate cells are compared and the carrier recombination at the rear Si/SiO2 interface is discussed using energy band diagrams.
