The effect of grating structure on the photoelectric conversion efficiency of solar cells is studied with the finite-difference time-domain method. The influence of grating shape, height and the thickness of coated metal film is analysed. It is found that the variation of grating shape and height makes great changes of energy storage, especially of the photoelectric conversion efficiency and energy storage of the triangle grating. The comparison between un-optimized and optimized surface grating structure on solar cells shows that the optimized grating surface significantly increases the energy storage capability and greatly improves the efficiency.

TiO2 films with three-dimensional web-like structure have been prepared by the photo polymerization-induced phase separation method (PIPS). Scanning electron microscopy and X-ray diffraction were used to characterize the as-prepared TiO2 films. The results showed that the film texture could be tuned by changing the composition of the precursor solution. The TiO2 film with web-like structure exhibited high photocatalytic activity for the degradation of methylene blue (MB) dye. The as-prepared films were used as the photo-anodes in dye-sensitized solar cells (DSCs). The photoelectric conversion efficiency of the DSCs was significantly enhanced by changing the POGTA/TTB in the precursor solution. Because of the increased dye adsorption active sites and efficient electron transport in the TiO2 anode film, a photoelectric conversion efficiency of 3.015% was obtained.

The structural morphology, arrangement of the nanocrystalline particles, porosity factor, surface state, crystalline phase and specific area of photoelectrode film have great influence on photoelectric performance of dye sensitized solar cells (DSSCs). At present, using TiO2 as the photoelectrode in the DSSC material has achieved very good photoelectric conversion efficiency. In this paper, the plating method is adopted to directly deposited the titanium coating on the conductive glass substrate, oxidizing the surface of titanium film, so that it is generated on the surface of titanium dioxide oxidation layer. Making it as the DSSC photoelectrode, obtained relative high photoelectric conversion efficiency.

This essay employed the "successive ion layer adsorption and reaction (SILAR)"technology to form PbSe/CdSe core/shell.We use the Pbse/CdSe core/shell replaced PbSe nanocrystals and obtained one new quantum dot solar cells of the inorganic.This new solar cells constituted by the metal oxide films retain the photoelectric conversion efficiency of quantum dot solar cells.At the same time,the stability of the new solar cells is tremendously improved with the oxidation resistance of inorganic oxide.Finally,when Jsc=25.2mA/cm2and Voc=0.36V ,we can conclude the conversion efficiency of the solar cell can be evaluated as 3.929%.

Triazoloisoquinoline-based organic dyestuffs were synthesized and used in the fabrication of dye-sensitized solar cells (DSSCs). After cosensitization with ruthenium complex, the triazoloisoquinoline-based organic dyestuffs overcame the deficiency of ruthenium dyestuff absorption in the blue part of the visible spectrum. This method also fills the blanks of ruthenium dyestuff sensitized TiO2film and forms a compact insulating molecular layer due to the nature of small molecular organic dyestuffs. The incident photon-to-electron conversion efficiency of N719 at shorter wavelength regions is 49%. After addition of a triazoloisoquinoline-based dyestuff for co-sensitization, the IPCE at 350–500 nm increased significantly. This can be attributed to the increased photocurrent of the cells, which improves the dye-sensitized photoelectric conversion efficiency from 6.23% to 7.84%, and the overall conversion efficiency increased by about 26%. As a consequence, this low molecular weight organic dyestuff is a promising candidate as coadsorbent and cosensitizer for highly efficient dye-sensitized solar cells.
