摘要：
Thin Films of ZnO were deposited by Chemical Bath Deposition. The "as grown" films are amorphous or polycrystalline depending upon the chemical composition of the aqueous solution and the temperature used for their deposition. After a thermal annealing at temperatures above 300 degrees C the films undergo a chemical phase transformation becoming ZnO. The films before and after the annealings show a bandgap around 4.2 eV and 3.3 eV, respectively. The ZnO films were used to make solar cells on CuInS2 prepared by chemical spray pyrolysis. Under AM 1.5 illumination, these devices show a short circuit current of the order of 10 mA/cm(2), an open circuit voltage of 350 mV and efficiency close to 2.2%.
