1. Title: [KIEcoE] High Efficiency CIGS Solar Cell by Coevaporation Method


2. Date and Time: Thursday, July 10, 2008 14:00~15:00


3. Place: Room 101, Creative Learning Building (E11)


4. Speaker: Prof. Byung Tae Ahn (Department of Materials Science and Engineering (MSE), KAIST)

                Ph.D. in Materials Science and Engineering from Stanford University(1989)

                Director, Center for Solar Cells Research at KAIST

                Research interests include Fabrication of thin-film solar cells (CdTe and Cu(In,Ga)Se2),  Growth of Si thin films and its application to thin-Si solar cells and thin-film transistors.


5. Abstract

Cu(InGa)Se2 thin-film solar cell have been developed because its high efficiency compared to other solar cells and cost competitive. A high efficiency CIGS cell was developed by careful control of metal composition and Se evaporation rate. Throughout the process and structural optimization an 18% efficiency has been realized in a small area cell. Since the efficiency is reproducible in laboratory level it is considered as very good result even though the value is lower than world record efficiency of 19.5%.
