Abstract :
A comprehensive design/technological study was conducted with the aim of obtaining high-efficiency BSF-type bifacial solar cells with reproducible parameters on large-area n-silicon and p-silicon wafers. The test devices were processed on 2-in. and 3-in. lower-grade single-crystal silicon wafers. Minimization of the cells´ cost was one of the sought-after objectives. Various procedures leading to a substantial increase of both the emitter and the base contribution to the generated photocurrent are described and tested experimentally.<>
