Energy crisis and environmental pollution is now serious global concern in 21st civilization life. Photovoltaics have gathered much attention as clean energy. Solar cell is semiconductor device which convert sunlight directly to electricity. In our laboratory, we are working on thin-film compound solar cells which have great potential on low-cost fabrication and high energy conversion efficiency. Our research covers broad spectrum of solar cell development, such as theoretical device design (modeling), thin film deposition, crystal growth, and device fabrication. Our main task is “proof-of-concept” for new material and new device structure; especially we are working on chalcogenide material and earth abundant semiconductors. Also, our activity includes flexible and light weight solar cells by new fabrication approach. To realize further popularization of PV, we are working on field test of PV modules and also promoting collaborations with companies and government.
