PCT No. PCT/CH94/00192 Sec. 371 Date May 31, 1995 Sec. 102(e) Date May 31, 1995 PCT Filed Sep. 27, 1994 PCT Pub. No. WO95/10856 PCT Pub. Date Apr. 20, 1995A photovoltaic cell (10) having a semiconductor substrate (11), a front passivation layer (12) arranged on the substrate, an emitter layer (14) having a first conductivity type (p or n), a front transparent conductive layer (15), a rear passivation layer (17) deposited on a rear surface of the substrate, a rear layer (18) producing a back surface field having a second conductivity type (n or p) opposite to the first conductivity type, as well as a reflecting element (19) comprised of a transparent conductive layer (20), an adhesion layer (21), and a reflecting layer (22). The disclosed cell has a substantially high efficiency a substantially low fabrication cost and is used in solar cells. |
