Solar Panel and Types , overview of solar adsorption cooling technology

A solar cell is an electronic device which directly converts sunlight into electricity. Light shining on the solar cell produces both a current and a voltage to generate electric power. This process requires firstly, a material in which the absorption of light raises an electron to a higher energy state, and secondly, the movement of this higher energy electron from the solar cell into an external circuit. The electron then dissipates its energy in the external circuit and returns to the solar cell. A variety of materials and processes can potentially satisfy the requirements for photovoltaic energy conversion, but in practice nearly all photovoltaic energy conversion uses semiconductor materials in the form of a p-n junction. With regard to the development of sustainable energy, such as solar energy, in this article we will Study types of solar cells and their applications.[۳]The increasing demand for electricity generated from main grids has necessitated the use of multiple microgrids, which serve as subsystems of the utility power. More recently, solar farms are being utilized for electricity generation, since solar irradiation is a green and sustainable renewable energy source. This energy source has witnessed high global growth figures, as more countries explore this alternative power source in the fourth industrial revolution. Solar panels are exposed to high temperatures due to the heat absorbed from the sun and this heat negatively impact its thermal control that lags its power generation. The excessive heat absorbed from the sun limits energy generated by the solar cells. Colling of solar panels is essential, especially on concentrated Photovoltaic (PV) systems. The paper focuses on an optimization option of an automated water spraying method that has effectively addressed a major gap experienced by the solar panel under hot weather conditions. The Introduction of a microcontroller-based thermal control water spraying system using an Arduino board was found to improve the efficiency of the solar cells. In the study, a solar collector cooling algorithm was designed and developed using a thermal control feedback system, which increased the efficiency of the solar panel array by ۱۶.۶۵%. [۵] he solar panel uses solar energy which is a renewable energy source, therefore, it is used in most commercial and non-commercial applications.
