Research Scheme Design of Copper-Based Chalcogenide Crystal Thin Film Materials for Solar Cells

Abstract:

The keys for development of copper-based chalcogenide crystal thin film solar cells are to improve efficiency and reduce costs. Oriented growth and band gap grading of its absorption layer crystal film are important ways to improve the efficiency. It proposed controllable preparation of this type thin film by chemical solution deposition and co-reduction, and study on the crystal orientation and regulation of the band gap gradient. It will design the composition and band gap gradient of multi-component and multilayer films, and establish the models for design, theoretical calculation and performance prediction; It will explore the effect of band gap gradient on electrical and optical properties and reveal the effecting laws and mechanism on electrical and optical properties.
