题目：High-efficiency nanostructured thin-film multi-junction solar cell
Thin-film crystalline high-efficiency and low-cost solar cells are expected to play a significant role for a greener energy source. Such cells have been extensively studied over the past 10 years. The James Harris group at Stanford University has proposed to develop significantly higher efficiency thin film c-Si based solar cells by combining multi-junctions and advanced nano-scale light management concepts in ultrathin film devices that lend themselves to very large scale, low cost manufacturing. In the past years, the Harris group have developed nanostructured solar cell modeling, epitaxial growth and fabrication. A nanostructured GaAs solar cell demonstrated improved Jsc, Voc, fill factor and efficiency. A dielectric nano-structure was designed and fabricated on c-Si thin film which demonstrated broadband and wide angle anti-reflection. The Harris group also collaborated with Solexel Inc. to apply this nanopatterning approach to commercial thin film c-Si cells.
Mr Yusi Chen is currently a Ph.D. candidate in professor James Harris's group at Stanford University. His research interests include silicon photonics, nanostructured thin-film solar cells and advanced material growth for renewable energy applications. He has also been working with many industry collaborators in the Silicon Valley, including Applied Materials, SolarJunction and Solexel. He received his master degree in Electrical Engineering from Stanford University at 2013 and bachelor degree in Microelectronics from Fudan University at 2011.
