Solar photovoltaic technology refers to the method of converting sunlight directly into electricity through the use of semiconductor devices known as solar cells. It has emerged as one of the most significant innovations in the pursuit of clean, renewable energy and offers a sustainable pathway to reduce dependence on fossil fuels, mitigate environmental degradation, and address climate change. The essence of this technology lies in harnessing the abundant and freely available energy of the sun and transforming it into usable electrical power without causing greenhouse gas emissions or air pollution. Over the last few decades, it has become a cornerstone in discussions concerning energy and environment, symbolizing the transition towards a low-carbon future. The underlying principle of solar photovoltaic technology is based on the photovoltaic effect, a phenomenon first observed in the nineteenth century by Alexandre Edmond Becquerel. The effect describes how certain materials, when exposed to light, generate an electric current. At the heart of a solar cell lies a semiconductor material, most commonly silicon, which is engineered to have a p-n junction.
