Nanostructures for photovoltaic solar cells and flexible transparent electrodes

Zhifeng Ren
Department of Physics and TcSUH, University of Houston, Houston, Texas

Abstract: Photovoltaic technology converting solar energy into electricity is playing a more and more important role in providing the society with clean energy and reducing the impact of burning fossil fuels on environment. How to increase the photovoltaic conversion efficiency has been studied very intensively during the past couple of decades. In this talk, I will present our effort using nanostructures to potentially improve the conversion efficiency by both designing new structures and inventing new transparent electrodes, specifically I will discuss our development on nano coaxial cable solar cells to separate the photon and charge path ways, ultra thin film solar cells for efficient light absorption, and super flexible transparent electrodes for efficient collection of charges.

He obtained PhD degree from the Institute of Physics of Chinese Academy of Sciences in 1990. His expertise is in materials synthesis and applications including superconductors, carbon nanotubes, ZnO nanowires, thermoelectric materials, photovoltaic materials, nano-bio materials and sensors, etc. Recently, he has focused on nanostructured thermoelectric materials, devices, and systems for efficient energy conversion using the enhanced thermoelectric materials he and his co-workers developed. He is a fellow of APS and a fellow of AAAS. He is the recipient of the 2014 Edith and Peter O'Donnell Award in Science from The Academy of Medicine, Engineering & Science of Texas (TAMEST). He is an elected fellow of the National Academy of Inventors.
