Dr. Byungha Shin gives talk at NU

February 2017

Dr. Byungha Shin of Korea Advanced Institute of Science and Technology (KAIST)  gives a Dravid Group special research talk on Emerging "Materials for PV and LED: CZTS and Hybrid Perovskites".

Abstract: 

Cu2ZnSn(S,Se)4 (CZTS) and hybrid perovskites are two emerging materials used for photovoltaic and light-emitting devices. Earth abundant and non-toxic materials hold special interest in the field of photovoltaics, however their performance suffers primarily due to open-circuit voltage loss. Dr. Shin will present his solutions to improve the open-circuit voltage through his work with the CZTS material system. In addition, the Shin group has developed novel synthesis conditions for perovskite materials which display beneficial property enhancements. The benefits to material properties and final device performance will be discussed as they relate to solar cells and LEDs based on methylammonium lead halide perovskites.
