Fabrication of cost-effective FTO/TiO2/CuO/Au heterojunction Solar Cell

ORAL

Abstract

Oxide heterostructures have great potentiality in the fabrication of low-cost solar cells. We have done experimental and simulation studies of the heterojunction solar cell using TiO2 and CuO as n-type and p-type layers, respectively. The thickness and dopant concentration-dependent simulations have shown, the solar cell operates at a maximum efficiency of 19.15% when the thickness of TiO2/CuO layers are chosen 1.4µm/1.2µm, with fluorine-doped tin oxide and gold as anode and cathode, respectively. Based on these simulation results, the solar cell on FTO substrates using pulsed laser deposition (PLD) for the TiO2 layer and spin coating for the CuO layer is fabricated. We have conducted structural-property correlations of individual layers using XRD, Raman, PL spectroscopy, SEM-EDS, and electrical measurements, e.g. hall measurements, and sheet resistance measurements. Results and analyses, confirm the successful growth of high-quality oxide layers of TiO2 (rutile and anatase phase) and CuO. The solar cell characterization is performed by the I-V measurements using a standard solar simulator. This facile and cost-effective fabrication of all oxide-based heterojunction solar cells will reduce overall cost and increase performance.
