fotovoltaisen

The term "fotovoltaisen" refers to photovoltaic technology, a method of converting light energy directly into electrical energy. This conversion is achieved through the photovoltaic effect, a physical and chemical phenomenon. When photons, the elementary particles of light, strike a semiconductor material, they can excite electrons, causing them to break free from their atoms. This liberation of electrons creates an electric current.

Photovoltaic cells, often called solar cells, are the fundamental building blocks of photovoltaic systems. These cells are typically made from semiconductor materials like silicon, which is treated with impurities to create a p-n junction. This junction is crucial for directing the flow of freed electrons, thus generating a direct current (DC). Multiple solar cells are then connected together to form a solar panel or module, which can then be further assembled into larger photovoltaic arrays.

The primary application of photovoltaic technology is in solar power generation. Photovoltaic power stations, ranging from small rooftop installations to large utility-scale solar farms, harness sunlight to produce electricity. This electricity can be used directly, stored in batteries, or fed into the electrical grid. Photovoltaic technology plays a significant role in renewable energy portfolios worldwide, contributing to efforts to reduce reliance on fossil fuels and mitigate climate change.
