The solar cells which are the most expensive parts of PV system were replaced by much cheaper optical elements when using concentration technology, thus the costs could be decreased further, and the concentrator solar cell was considered to be one of the third generation solar cells .
... Solar concentrators also generate heat on the PV cell. The increasing temperature causes the efficiency of the PV cell to reduce . ... PDF | Solar technology offers great potential in terms of supplying the world's energy needs.
Solar technology offers great potential in terms of supplying the world’s energy needs. However, its current contribution to the world is still limited. The main factor is related to high initial cost of building the system. This paper will provide a n up-to-date review of solar concentrators and their benefits to make solar technology affordable.
... A concentration-type solar cell is the most promising strategy for reducing the cost of materials and improving the efficiency of solar cells. GaAs was proposed for use in high-efficiency solar cells because it has a band gap of approximately 1.4eV, which is the theoretical high efficiency .
Thus, the series resistance of the concentrator silicon solar cell must be made lower than that of common silicon solar cells to decrease the power losses under concentration to keep the high efficiency, and the series resistance could be decreased by changing the structure of the cell. 4.
