The main objective of this communication is the investigation of the influence of thermal treatment in H2 on the parameters of In/nITO/P2O5/pInP/Ag:Zn solar cells obtained by ITO layers pyrolithic pulverization. The ITO/pInP heterostructures obtaining take place at the temperature of 450ºC. The photoelectric parameters of the solar cell received on InP wafers with concentration p = 3·1017cm-3 after the thermal treatment are Voc=0.626 V, Isc = 22.72 mA/cm2, FF = 71%, Eff = 10.09%. As a result of these investigations it was shown that the thermal treatment of In/nITO/pInP/Ag:Zn SC in H2 at 350oC during 10 min. leads to considerable improvement of their photoelectric parameters.
