Design for Amorphous Silicon Solar Cells

This document explains and demonstrates how to design efficient amorphous silicon solar cells. Some of the fundamental physical concepts required to interpret the scientific literature about amorphous silicon are introduced. The principal methods such as plasma deposition that are used to make amorphous siliconbased solar cells are investigated. On the basis, high-efficiency solar cells based on amorphous silicon technology are designed. Multi-junction amorphous silicon solar cells are discussed, how these are made and how their performance can be understood and optimized. To conclude this document, some of the directions that are important for future progress in the field are presented.
