Abstract

CdTe solar cell is found favourable material for solar cell due to its ideal energy band gap, absorption coefficient, and higher efficiency. The efficiency and performance of CdTe solar cell can be further improved by adding ZnO as front contact. Zinc oxide has both semiconducting and piezoelectric properties, which makes it an optimum choice front contact for any solar cell. ZnO is one of the best options for nanostructures among all materials due to its structures and properties. In this paper, ZnO thin film has been analyzed using the one-dimensional simulator AMPS-1D to determine its' maximum efficiency. Different parameter of ZnO (100nm) thin film is simulated such that sun intensity, temperature, thickness, relative permittivity, mobility and effective density of state. The maximum efficiency of ZnO thin film is found 22.836%. The study highlights the changing of different parameter of ZnO thin film and improves its efficiency.
