Dr Zhengfei Wei

Technology Transfer Fellow, Swansea University

Zhengfei joined SPECIFIC as a Technology Transfer Fellow in 2015. His research focuses on fabrication and up-scaling of efficient and cost-effective Cu2(Zn, Sn)(Se,S)4 solar cells. The goal of his research is to incorporate of thin film PV onto cost-effective, flexible and building materials substrates such as metal or plastic foils by using various low cost deposition methods to grow high quality kesterite films along with optimisation of buffer and transparent conductive oxide layers.

Zhengfei obtained his PhD at Heriot-Watt University in 2014. His thesis entitled “Process development and optimisation for efficient and cost-effective Cu(In,Ga)Se2 thin film solar cells”. He involved in the development of a pilot scale co-evaporation system which is capable to deposit CIGS films on 30 cm × 30 cm substrates. He used a range of cost-effective deposition techniques (RTP, mechanical compression, ultrathin CIGS absorber etc.). Prior to join SPECIFIC-Swansea University,  he worked in the Laboratory for Thin Films and Photovoltaics, Empa, Switzerland for three months as a visiting researcher to work on a project of “Fabrication of high efficiency CIGS solar cells using low temperature co-evaporated C-I-G-S precursors and RTP”.
