PHOTOELECTRIC PROPERTIES OF ITO P(+)-P(-)-INP SOLAR-CELLS IN LINEARLYPOLARIZED-LIGHT/

Indium phosphide heterostructures and transparent conducting films of wide-gap oxides have previously been used in the development of highly efficient solar cells, making it possible to bring their efficiencies up to 18% [M, M. Koltun, Optics and Metrology of Solar Cells [in Russ ian], Nauka, Moscow (1985); V. M. Botnaryuk, L. S. Gagara, L. V. Gorch ak et al., Geliotekhnika 23, 37 (1990); V. Botnariuc, L. Gagara, E. Ne gru et al., Solar Energy in Romania 2(1), 53 (1993)]. In the present p aper results are reported from the first studies of the photoelectric properties, in linearly polarized light, of solar cells consisting of a heterojunction between single crystal indium phosphide and a mixed i ndium and tin oxide film (ITO film, E-g congruent to 3.6 eV [G. Check and A. Genis, Solid Stale Techol. 23(1), 102 (1980)]). (C) 1998 Americ an Institute of Physics. [S1063-7842(98)01305-1].
