Popis: Microwave conductivity is observed in TiO2 and CuI films at room temperature. Organic dye pyrogallor red is found to sensitize TiO2 and CuI in solid-state TiO2∣dye∣CuI cells. Effect of ligands attached to crystal growth inhibitors on morphology of CuI films is studied. A weaker crystal growth inhibition was observed when size of ligands attached to surfactant is increased. Reasonable explanations are given for observed inhomogeneous photocurrent and its degradation under illumination.
