Solar energy directly converses light energy into DC power without fuel, no moving parts, no pollution, and no noise with long life-span more than about twenty years. Its application is extensive and the set up of solar generation can be scattered and in a small amount on demand which is the most available of all renewable energy, and is the most practical and effective energy. There are many kinds of solar cell, such first generation as Mono-crystalline Silicon, Multi-crystalline Silicon, and Amorphous Silicon, the second generation as Film Photovoltaic and the third generation as Dye-Sensitized (DSSCs) etc. The utilization of solar energy is greatly influenced by environmental change with the main reason of solar radiation. This research collects the data from the test of Mono-crystalline Silicon, Multi-crystalline Silicon, and Film Photovaltaic solar cells in different solar radiation, and then conducts the analysis and research thereby. Using the program written by Labview, collect the data of voltage, current, and the power, solar radiation, and temperature emitted by solar cells under test for analysis. And then discuss the results of the collected data by Matlab for data analysis.

TiO2nanotubes were successfully synthesized by anodization method of Ti foils. The electrolyte was composed of ethylene glycol (EG), ammonium fluoride (0.3%wt NH4F) and de-ionized water (2% vol H2O). A constant DC power supply of 50 V was used during anodization with anodizing times of 1 hour, 2 hours, 4 hours and 6 hours. The samples were annealed at 450 °C for 2 hours. The TiO2nanotubes were studied by X-Ray Diffraction (XRD) and Scanning Electron Microscopy (SEM). Structural analysis revealed the presence of pure Ti, and the crystalline anatase phase due to transformation of amorphous TiO2after annealing. The morphology of TiO2nanotube sizes showed an increase in tube diameter with anodizing time from approximately 50 nm to 200 nm. However, the efficiency of dye-sensitized solar cells increased with anodizing times up to a maximum of 5.74 % for anodizing time of 4 hours.

The thermodynamic dissipations in crystalline silicon solar cells are identified and evaluated. The ratio of the exergy of the output electrical power to the exergy of the input solar radiation is the effectiveness of the solar cell. The input exergy is converted to the output exergy (the electrical power delivered) with a series of dissipations. These dissipations are identified and evaluated for crystalline silicon cells in terms of the thickness and certain fundamental properties of the light absorbing silicon semiconductor (in this case a P-type material). It is assumed that the N-type material is very thin and absorbs no radiation. For representative values of these properties and a range of thicknesses, it is found that the dissipations due to transmission and thermalization and in the photogeneration process are dominant. The dissipations due to the dark current and recombination are small.
