New Directions in Silicon Solar Cell Technology

This project identifies the main obstacles to the development of silicon solar cells and proposes innovative solutions to them. By opening new directions in the type of base material and in the fabrication technology used to make solar cells, it aims to break through the last remaining barriers to reaching their ultimate performance. The focus is on heterojunction devices based on hydrogenated amorphous silicon onto n-type crystalline silicon wafers. The most significant outcomes will be the development of advanced contacts compatible with achieving 26% conversion efficiencies and the fabrication of a new class of solar cells.
