Novel Model

A novel model for analyzing the conversion efficiency of mono-crystalline silicon solar cells is improved based on the detailed balance principle. The maximum theoretical conversion efficiency of the conventional planar mono-crystalline silicon solar cells has been updated to 27.94% according to the improved model. Furthermore this model is extending to cylindrical coordinates for estimating the radial p-n junction mono-crystalline silicon solar cells. A radial p-n junction mono-crystalline silicon solar cell with the highest conversion efficiency of 32.9% has been designed as that the radius of n-Si core is 1 µm, the radius of the cylinder is 40 µm, and the height of cylinder is 100 µm.

Irradiance Spectrum

The spectral response of the Si solar cell does not coincidence with the sun irradiance spectrum, so the efficiency of the Si solar cell is not high. To improve the Si solar cell one try to make use of most region of the sun spectrum by using dyes which absorb un useful wavelengths and radiate at useful region of spectrum (by stock shift). Fluorescence's dye is used as luminescent concentrator to increase the efficiency of the solar cell. The results show that the performance efficiency and out power for crystalline silicon solar cells are improved.
