Renewable Energy-Solar PV

1. Use the P/N type semiconducting generate power make the power equipment running 

2. Upon absorbing the photon energy supplied by sunlight, electrons and holes inside semiconducting materials are excited from their current atomic orbital and travel through the cell till they reach an electrode

3. Solar energy can then be generated and stored via photo-thermal conversion (e.g. solar collectors) and photovoltaic conversion (e.g. photovoltaic modules)
