Abstract: Design of high-effective photovoltaic devices needs not only nanoscaled materials and structures but also classical semiconductors with various widths of the gap and microscaled heterojunctions. This book reviews and describes the principal physical chemical properties of wide gap semiconductors. The authors consider methods of fabricating films and nanostructures with controllable characteristics. The structural properties are presented and the optical and electrical characteristics and effects of different defects (structural and point defects, one- and two-dimensional defects) are also presented. The book also discusses the current mechanisms and influence of the material interface perfectness and electrical characteristics of heterostructures based on thin films of PbS and solid solution ZnCdHgTe. The book shows unique properties of nanostructured metallic cluster contacts obtained by chemical technology for high effective solar cells. (Imprint: Nova)
