Investigating the properties of semiconductors solar cells technologies, efficiency for photovoltaic cells and application graphene for solar cells : A review

Abstract

The increase in global energy consumption and greenhouse gas emissions over the last century has been related to increased pollution and irreversible damage to important resources. To reduce the global dependence on natural resources and pollution, many scientific efforts have been made to reduce the energy production costs from renewable sources, including efforts to exploit the inherent properties of semiconductors to generate electricity using sunlight. Solar batteries based on the first semiconductor, with efficiencies of >10 %, were produced between 1950 and 1960. Currently, 80–90 % of photovoltaic components worldwide are made from silicon sheets. The use of semiconductors is revolutionizing the optical and electronics industries. Understanding the properties of semiconductors is important for understanding the activity of solar cells and improving their performance and conversion efficiencies. To generate electricity, solar cells must produce electricity and tension. Electricity is produced by motion loads, and tension requires a difference between electronic energy levels. Metal and insulation are free loads, and there is a prohibition between electronic energy levels. However, semiconductors have several advantages over metals. For a highly effective conversion, an effective load must occur, which depends on factors such as the diffusion length of the electrons and holes. The creation and recombination of electrons and their vulnerabilities are of utmost importance in solar cells. This article offers a detailed review of advanced solar sun cell technologies, new materials, loss mechanisms, and efficiency-improvement techniques. Research includes silicon materials (Si) and III-V, punishment lines of lead, durable embryos, organic photovoltaics, and solar cells that are aware of colors. In this context, promising architectural progress with graphene and super materials has been emphasized in the literature. This study also included different types of losses, including interior and external losses, in the single solar cells. Techniques to improve efficiency, such as light management and spectrum use, have been evaluated. Although the effect of solar cells based on Si is delayed by approximately 25 %, the effectiveness of multi-transition solar cells based on III-V semiconductor compounds is improved. However, mixed III–V semiconductors are subject to high material costs. In addition, indium gallium and cadmium telluride solar battery technologies can compete with crystalline solar cells owing to recent progress in cell performance. However, environmental concerns and open tensions regarding the remaining Cd are prevalent. In contrast, perovskite solar cells are highly efficient for both single and multiple arrays. The industrialization of perovskite solar cells requires consideration of device degradation, hysteresis, and film quality.
