Project Title: Ultra High Efficiency Thin Film Multi-junction Solar Cell Pi
نویسنده
چکیده
The Harris group proposed to develop significantly higher efficiency thin film multi-junction solar cells by combining multi-junctions and advanced nano-scale light management concepts in ultra-thin film devices that lend themselves to very large scale, low cost manufacturing. In the past year, they developed thin-film nanostructured solar cell modeling, epitaxial growth and fabrication. A nanostructured ultra-thin-film GaAs solar cell (300 nm) demonstrated improved Jsc, Voc, fill factor and efficiency. The voltage enhancement on a 5-μm-thick Si cell was demonstrated, which achieves a Voc of 649 mV. They also developed bonding process and luminescent coupling modeling for multi-junction solar cells based on Si.
