The possibility of growing the (GaAs)1–x–y(Ge2)x(ZnSe)y alloy on GaAs substrates by the method of liquid-phase epitaxy from a tin solution–melt is shown. X-ray diffraction shows that the grown film is single-crystal with the (100) orientation and has the sphalerite structure. The crystal-lattice parameter of the film is af = 0.56697 nm. The features of the spectral dependence of the photosensitivity are caused by the formation of various complexes of charged components. It is established that the I–V characteristic of such structures is described by the exponential dependence I = I0exp(qV/ckT) at low voltages (no higher than 0.4 V) and by the power dependence J ~ Vα, where the exponent α varies with increasing voltage at high voltages (V > 0.5 V). The results are treated within the framework of the theory of the drift mechanism of current transfer taking into account the possibility of the exchange of free carriers within the recombination complex. © 2016, Pleiades Publishing, Ltd.

A semiempirical equation for the temperature dependences of the photoelectric parameters of a-Si: H solar cells is derived to explain the experimental results. Based on a comparison of the calculation results and experimental data, it is shown that the nonideality coefficient of the CVC of solar cells exhibits a weak temperature dependence. © 2011 Allerton Press, Inc.

This paper discusses the I sc and U xx temperature dependencies of n +-p and n +-p-p + structures made of comparatively fine-grained secondary cast polycrystalline silicon upon their being homogenously heating and heated with a temperature gradient, as well as upon alteration of heat flux direction. © 2011 Allerton Press, Inc.
