3 Brief history Antoine Becquerel first described the photovoltaic effect in 1839, and Albert Einstein explained the mechanisms in 1912 When a material is exposed to sunlight, exposed atoms release electrons The «free» Electrons create a continuous low voltage In the 1950s teams of Bell Laboratories manufactured the first crystalline silicon cell First commercial applications with space programs A real interest born from the second oil shock (early 1980) for terrestrial energetic applications In 1963 the first cells are installed in Japan Today, photovoltaic cells are present in various applications 3

4 Some examples of applications General public applications (few watts) Installation in the residential (1 to 5 kw) Installations in buildings (few 100 kw) Solar Farms (few megawatt) 4

5 Current generation A cell 70 mm A photovoltaic cell is made from a slice of silicon N doped zone 300 m P doped zone Photons A slice of silicon The silicon is doped with impurities. This creates an area with excess electrons (N zone) and a deficit of electrons or holes (P zone) The energy of photons from the sun will release electrons The electrons will recombine with holes through the external circuit to balance the junction : A direct electrical current is generated 5

6 The main manufacturing technologies Mono crystalline silicon cells ( M-Si ) Higher efficiency Quite high manufacturing costs Poly crystalline silicon cells ( P-Si ) Widely used Cheaper than mono crystalline Thin film or amorphous silicon cells ( a-si ) Lower efficiency but better than crystalline on diffuse radiation Cheaper than polycrystalline Suitable to large building projects, roof or cladding systems Flexible and lightweight 6
