Abstract
The structural, transport and optical properties of screen printed Cu( x)S thick films with possible application in photovoltaic and photothe rmal devices are reported. The X-ray diffraction studies show that the screen printed films are stable up to about 220-degrees-C in air and belong to the Cu(x)S structure. Above this temperature it decomposes m ainly to CuSO4. The electrical conductivity depends on the sintering t emperature and the amount of flux, Cu(NO3)2, used in the paste for scr een printing. The differential scanning calorimetry studies reveal the phase changes occurring during heating and pertaining to the dependen ce of electrical conductivity on the sintering temperature. A configur ation consisting of screen printed Cu(x)S on chemically deposited and annealed (at 200-degrees-C) CdS thin film exhibited rectification.
