2. Components of a photovoltaic system

2.1 Photovoltaic modules

A photovoltaic module consists of photovoltaic cells connected in series and in parallel. Photovoltaic cells are primarily made of silicon (over 97% of the market) and come in the form of wafers measuring 182 to 210 mm on each side, with a thickness of only 110 to 150 µm. These silicon wafers consist of a PN junction for the separation of electrons and holes. They benefit from optical optimization through surface texturing and an anti-reflective coating to capture as much...
