Abstract : Studies directed toward the fabrication of high efficiency solar cells on silicon webbed dendrites and the solar cell panels were undertaken. Some of the basic design considerations and fab rication techniques are presented. Preparation of P(+)N and N(+)P solar cell structure is discussed. Cell efficiencies were measured using two tungsten photoflood lamps as the light source. Efficiencies as high as 13% were achieved on 2cm x lcm x 0.05cm, as high as 12% were achieved on 15cm x 1cm x 0.05cm, and as high as 10% were achieved on 30cm x 1cm x 0.05cm solar cells prepared from silicon webbed dendrites. Spectral response measurements were made on silicon web solar cells and typical curves are presented. One mechanical sample, four operational solar cell panels, and two special operational panels were fabricated, tested and submitted in part fulfillment of the subject contract. Complete results on these panels are discussed. (Author)
