Abstract
|
Conventional solar cells are used in the market is bulk silicon crystalline masses that their production cost is really high, but thin film solar cells , thin layer of silicon , their production cost is low. But due to their low absorption of light has low efficiency than conventional and expensive solar cells. Here, using one dimensional photonic crystal as a brag reflector mirror to reflect light, the absorption rate in cell is increased. The results are simulated by finite element method which is challenging and low cost.
