What is WO3 Thin Films for Solar Cell Applications about?

This document summarizes a study on the structural, optical, and surface properties of tungsten oxide (WO3) thin films deposited by radio frequency reactive sputtering for potential use as transparent back contacts in solar cells. X-ray diffraction analysis showed that as-deposited films were amorphous, while films annealed at 400°C and 500°C crystallized into the monoclinic phase of WO3. Optical measurements found that the bandgap decreased from 3.30 eV for as-deposited films to 3.17 eV after annealing at
