The embodiment of this invention lies on experimental evidence of photoconductivity activity of a hybrid solar cell, organic/chalcogenide. The device is made of thin layers of conductive indium-tin-oxide (ITO) on glass with a 100 nm layer of chalcogenide molybdenum di-sulfide (MoS2) and a thin layer of about .about.50 nm of complex organic compound assembled at room temperature. The device was tested to conventional electrical transport measurements in the regime of -1V to 1V under electromagnetic radiation simulator at 100 mW/cm2. Results indicate solar conversion efficiency of 2.48% and current density of 6.35 mA/cm2.
