Abstract
The two major bottlenecks of developing solar cell are cost effective and solar cell efficiency. Not all incident light of spectrum is absorbed by solar cell and transformed to current completely in the fact. The maximum efficiency of the single solar cell is about 25% which is almost achieved to the theoretical value. The thesis mainly studies on spherical solar cell combining with reflector and mentions the way that can increase the power of electricity output.
It not only increases the region of incident light, but also increases the power of electricity output at the same time if designing the reflector system of spherical solar cell has be done. Design the better reflector (Type B and Type C) geometrically, calculate the Shape Factor of incident light to the Si spherical and the area of incident light with mathematics in the thesis. The two new types (Type B and Type C) of the reflector system are increased the region of incident light by using the incident light which reflects it to the bottom of the spherical. The incident light of region can be reached approximating 100% as the incident light is 90°.
