Abstract
With the lack of fuel energy, the renewable energy becomes the best alternatives to support our life. The wind energy and solar energy become very common to generate power, solar cells and solar panels are used widely. However, the efficiency of conversing sunlight to power still needs to be improved. Therefore, different shapes of nano-grating structured GaAs solar cell have been built to improve the sunlight conversion efficiency, such as triangular, rectangular, trapezoidal, and parabola shaped nano-grating structure solar cell. The main objectives of this dissertation are to construct different nano-grating shaped GaAs solar cells with various grating heights and grating pitch and compare the simulation results and find the one with higher conversion efficiency. The grating height ranges are from 50 nm to 500-nm and the grating pitch ranges are from 200-nm to 810-nm. The OptiFDTD simulation tool has been used to simulate the different shaped nano-grating structure solar cells. According to the previous research, among triangular, rectangular, and trapezoidal shaped nano-grating structure GaAs solar cells, the triangular shaped nano-grating structure solar cell has the best conversion efficiency. Hence, the parabolic shaped nano-grating structure GaAs solar has been built to compare the conversion efficiency by the light reflection curves, light transmission curves and light absorption curves. Based on the simulation results, it has confirmed that the parabolic shaped nano-grating structure solar cell has good conversion efficiency when the grating pitch at 810-nm.
