Photovoltaics - What is it?The wordThe word "Photovoltaics (PV)" consists of two parts: "photo" meaning light and "voltaic" meaning electricity. "Photovoltaics" means the generation of electricity from light. The Process of Generating Energy from LightSemi-conductor materials can be adapted to release electrons - the negatively charged particles which form the basis of electricity. All PV cells have two layers of semi-conductors - one positively charged and one negatively charged. When light shines on the semi-conductor, the electric field across the junction between these two layers causes electricity to flow. This generates DC current which can be converted into AC using an inverter. The Technique
The PV Modules
- generating DC current which can be converted to AC current using an inverter - a PV-system does not need bright sunlight - it still can generate electricity on cloudy days |
