Abstract
Natural gas, oil, coal, and nuclear power are all finite and highly depleted energy sources. Today, as a practical substitute for the use of polluting fossil fuels, energy based on green resources has attracted significant interest and investment worldwide. The most plentiful source of this renewable energy, There are two types of solar energy: light and heat. One of the most common solar energy harvesting technologies to convert light directly into electricity is the photovoltaic (PV) solar cell (SC). The global market share for photovoltaic modules made of bulk crystalline silicon (C-Si) is currently around 90%.One of the most effective materials for absorbing wide-band light is silicon (Si), where a planar C-Si SC’s power conversion efficiency (PCE) can reach 22% [1]. C-Si SC, however, has a high price. In order to lower the high cost of the conventional C-Si SC, a second generation SC technology based on low-purity thin-film (TF) materials has been developed. However, because of the short optical path length, the conversion efficiency is only about 12%. Utilizing light trapping techniques, the third generation of solar cell technology has increased the light absorption in TF-SC. This method lengthens the optical path and encourages the production of e-h carriers, both of which boost the effectiveness of TF SCs. As a result, a cost-effective TF SC can be created using less active material. This thesis introduces and studies numerically a novel design of Modified conical silicon Nanowires solar cell (NW SC).
