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.
