Opportunities,challenges and solutions of organic solar cells;

In this paper the progress of main fields of organic semiconductor is introduced, including the fields of organic light emitting devices, organic photoconductors, organic solar cells and organic thin film transistors.

The thin films of poly[2-methoxy-5-(2′-ethylhexyloxy)-1,4-phenylenevinylene](MEH-PPV) used as active layer in organic solar cells and the single-layer devices with structure of ITO/MEH-PPV/Al were prepared by the spin-coating method,respectively.

A Copper(II) phthalocyanine(CuPc)/fullerene(C60) organic solar cell doped pentacene is fabricated in Indium-tin-oxide(ITO) glass with high-vacuum evaporation technology.

The fundamental principles and researching developments of organic solar cells are briefly introduced and the current fabricating methods and technical improvements of zinc oxide(ZnO) nanorods/polymer hybrid solar cell are reviewed as well.

In this paper, porphyrin and its derivatives as photosynthetic reaction center that mimic certain aspects of photoinduced electron transfer and energy transfer, attractive candidates for organic solar cells, molecular optoelectronic devices, organic light-emitting diodes,data storage, and other ap.

In recent years, the study of organic solar cells has attracted much interest and obtained great achievements due to their low cost, easy of fabrication, and procession temperatures which are suitable for fabrication onto lightweight plastic substrates.

The research progress of the materials and devices of organic solar cells were summarized systematically in this dissertation.

In this paper,basic properties, the structures,the theory, the research status as well as defect and cause of organic solar cell are introduced, and the trends in the development of such devices are also presented.

Comparing with the traditional silica solar cells, organic solar cell is low-cost, highly flexible and green, so the research in this field has caused widely attention.
