The linear dependence between the thickness and sediment amount of chemical surface deposition was demonstrated by the firs time.The principles of chemical surface deposition technology for fabrication of stoichiometric CdS films (d=0-100 nm) from aqueous solutions of cadmium salts (CdSO4, CdCl2, CdI2) at temperatures T <363 K was developed. The CdS films weare polycrystalline with low concentrations of surface makrodefect (107sm-2) and possesses semiconductor properties. It was proved that the CuInSe2xS2(1-x) semiconductor solid solutions thin films can be fabricated by chemical deposition. The physical and chemical basis of such films, alternative to СuIn1-хGахSе2, fabrication technology was developed. The conditions for fabrication of CuInSe0,24S1,76 semiconductor solid solution thin films with bandgap Eg~1,50 eV, suitable for absorber layer in heterojunction with CdS films was . In the known method close space sublimation, the new modes for polycrystalline p-CdTe films fabrication, with a uniform composition distribution and thickness in the residual gas pressure P = 4,5 o 10-4Pa, was proposed. The of research results that provide a polycrystalline p-CdTe films. The fabricated polycrystalline cadmium telluride film were homogeneously structured with thickness d = 0,76-38,52 mkm with randomly oriented crystallites. The laboratory technology for photosensitive heterostructures n-CdS/p-CdTe, n-CdS/p-CuInSe2xS2(1-x) (x = 0,12-0,32) fabrication, which are characterized by good reproducibility of rectifying and photoelectric properties in the broad (1,37-2 5 eV) spectral range, was proposed. It was demonstrated that selenium content in the CuInSe2xS2(1-x) solid solutions films controls the length spectral range (1,485-1,374eV) of the high heterostructures photosensitivity
