About Dr. Chen

Dr. Tar-pin Chen received his B.S. in Physics from Chung Yuan University (Taiwan) in 1970, his M.S. in Physics from the University of Waterloo (Canada) in 1972 and his Ph.D. from the State University of New York at Buffalo in 1978. He has been at the University of Arkansas at Little Rock since 2005, before that he held positions at the University of North Dakota, Vinnaova University, and the Solid State Division of Ames Laboratory and Iowa State University. Dr. Chen's research interests include nanometer devices and materials, nanometer thickness solar cell materials, quantum bit devices and terahertz dictators.

GREEN Research

Dr. Chen's chalcogenide light absorber and nonowire solar cell research focuses on copper indium gallium sulfide or selenide (CIGS) and copper zinc tin sulfide (CZTS). CIGS and CZTS are prepared by both vacuum and solution processes. Optica, eelctrical and structural properties of these materials are investigated. Both thin-film and nonwire solar cells are fabricated. A technical procedure for fabricating nanowire solar cells is being developed. Nontoxic buffer layers using Mg-doped ZnO as a bugger have been fabricated. His graphene window research focuses on large-area single- and few-layer graphene grown by chemical vapor deposition (CVD) in vacuum. Its optical and electrical properties are investigated. Currently graphene with a size of 2x2 cm^2 have been obtained. A large size can be obtained easily if using a furnace with a large diameter. By controlling the growth condition, the number of layers can easily be controlled. This will be used for solar cell windows.
