Cuprous oxide (Cu O)-based solar cells containing zinc oxide (ZnO) were fabricated on F-doped tin oxide (FTO) by electrodeposition. Cu O layers were deposited from a pH-adjusted electrolyte consisting of LiOH, NaOH or KOH. A photovoltaic device based on a FTO/ZnO/Cu O/Au heterojunction structure was prepared using LiOH, and it gave a power conversion efficiency of 1.43% under air mass 1.5 illumination. © 2013 The Japan Society of Applied Physics. 2 2 2

Fullerene-based solar cells with normal and inverted structures containing phthalocyanine and naphthalocyanine dimers were fabricated by vacuum evaporation. Power conversion efficiencies were measured under simulated sunlight conditions. Fabricated devices exhibited high stability in air and a wide optical absorption from 320 to 800 nm. A carrier transport mechanism is proposed based on the energy level diagram. © 2013 Elsevier B.V. All rights reserved.

C fullerene and 5,10,15,20-tetrakis(4-aminophenyl)porphyrin (TAPP) composite micropowder was prepared by simply mixing C and TAPP in an organic solvent under ambient conditions. The composite micropowder contributed to photoelectric conversion, which was confirmed by a semi-wet-type photovoltaic application. © 2013 The Chemical Society of Japan. 60 60

Organic solar cells have a potential for use in lightweight, flexible, inexpensive and large scale solar cells. However, significant improvements of photovoltaic efficiencies are mandatory for use in future solar power plants. One of the improvements is donor-acceptor proximity in the devices, which are called bulk heterojunction solar cells. Bulk heterojunction is an efficient method to generate free charge carriers, and the charge transfer is possible at the semiconductor interface. The purpose of the present work is to fabricate and characterise C based solar cells with copper oxides, CuInS , phthalocyanines, porphyrin, poly-vinylcarbazole, nanodiamond, germanium and exciton diffusion blocking layers. In the present work, C and fullerenol [C (OH)10-12] were used for n-type semiconductors, and metal copper oxides, metal phthalocyanine derivative, porphyrin and poly-vinylcarbazole were used for p-type semiconductors. In addition, nanodiamond and germanium based molecules were added into the active layers of the solar cells. The novel aspect of the research is to investigate the relation between properties and microstructures of the solar cells using transmission electron microscopy, X-ray diffraction and electronic structure calculation. The impact of the research concerns the study of organic solar cells by means of microstructural analysis, property measurements and theoretical calculations. © 2013 W. S.
