Application of Photovoltaic (PV) Cell and Limited Factor

Abstract

With the concept of carbon neutrality and carbon emissions peak, the Chinese government emphasize the importance of the application of renewable energy like photovoltaic energy. Internationally, some countries and regions already have ability to replace fossil energy with renewable resources such as wind, solar, wind, and hydrogen energy. This thesis focuses on photovoltaic energy and its applications. Photovoltaic energy usually uses monocrystalline silicon and polysilicon as raw materials, and this paper compares the advantages and disadvantages of both raw materials. The technology of building PV integration, which combines PV cells with buildings, and the technology that increases the conversion efficiency of PV cells by passivating the back contact of the emitting area are described in detail. In addition, this study illustrates the reasons that limit the development of photovoltaic cells under the current technology in terms of both self-factors and environmental factors. The self-factors are mainly the conversion rate of its own materials and energy consumption of meta-components, and the environmental factors are mainly the geographical location leading to the solar altitude angle and the amount of solar radiation. In the future, the global PV market will continue to maintain a rapid growth trend, driven by favorable factors such as the continued decline in the cost of photovoltaic power generation and the positive market orientation.
