About this document
High-Efficiency GaAs Solar Cells Report by Saif Uddin is a document available to read on EtoBox.
This document provides a final report on research into developing high-efficiency solar cells on polycrystalline substrates. Key findings include: 1) Gallium arsenide (GaAs) growth was optimized on polycrystalline germanium (poly-Ge) substrates, with minority carrier lifetimes measured in GaAs structures. 2) Baseline GaAs solar cells on single crystal Ge achieved efficiencies up to 18.5%, while cells on poly-Ge reached a maximum efficiency of 14.5% after optimizing defects, contacts, dark current reducti
