Solar power is today the fastest-growing renewable energy source in Europe as well as globally. At the heart of this technology is photovoltaic energy.
Simply put, this is the process of turning sunlight directly into electricity using photovoltaic cells. These cells are made of semiconductor materials, like silicon, which exhibit the photovoltaic effect. The magic of solar power happens when these materials generate an electric current upon exposure to light.
Solar energy itself is not a new concept. It dates back centuries, with ancient civilisations harnessing the sun’s energy. Modern advancements, such as increased efficiency and large-scale solar parks, highlight its potential. Understanding the physics behind photovoltaic energy, from solar irradiance to the photovoltaic effect, reveals the intricate process of generating clean electricity. Despite challenges like seasonal variability, innovative solutions are paving the way for a sustainable future.
But first let’s deep dive into the history of solar power to appreciating its significance today.
