Complete analysis and understanding of solar energy and its use to optimize energy consumption in buildings

The Sun is the star at the center of the Solar System. It is a nearly perfect ball of hot plasma, heated to incandescence by nuclear fusion reactions in its core. The Sun radiates this energy mainly as light, ultraviolet, and infrared radiation, and is the most important source of energy for life on Earth. As one of the infinite, clean and affordable energy sources, the sun can revolutionize the future of energy and fuel. Solar energy is radiant light and heat from the Sun that is harnessed using a range of technologies such as solar power to generate electricity, solar thermal energy (including solar water heating), and solar architecture. Solar energy is the sun's radiant light and heat harnessed using a range of evolving technologies such as solar heating, photovoltaics, solar thermal energy, solar architecture, molten salt power plants and artificial photosynthesis. Active solar techniques include the use of photovoltaic systems, concentrated solar power, and solar water heating to harness energy. The growth of global energy consumption in the last century, and with it the increase in greenhouse gas emissions, has been accompanied by more and more environmental pollution and irreparable damage to vital resources. In order to reduce the global reliance on finite natural resources and environmentally harmful fuels, many scientific efforts have been made to reduce the cost of producing energy from renewable sources. For example, the attempt to generate electrical energy using sunlight has been made using the inherent property of semiconductors. The first semiconductor-based solar cells with efficiencies of more than ۱۰% were built in the ۱۹۵۰s and ۱۹۶۰s. Currently, ۸۵ to ۹۰% of solar photovoltaic components worldwide are made on the basis of thin silicon crystal tablets. Today, the use of semiconductors has revolutionized the optical and electronics industries. In this article, we have tried to introduce solar energy as one of the new and valuable energies and while introducing the photovoltaic phenomenon, the solar cell is introduced as a tool to benefit from this gift. Then, different types of solar cells have been briefly introduced based on the time of their creation.
