The first semiconductor p–n junction solar cells were described in 1941 by Russel Ohl of Bell Laboratories [6].These junctions formed naturally in slowly solidified melts of silicon (Fig. 4).Exploration of their properties led to the understanding of the role of p- and n-type dopants in controlling semiconductor properties and hence to the microelectronics revolution [3], [7].
Det är förhållandevis dyrt att installera solceller (man får betala omkring 16 000 kronor för varje installerad kilowatt), men det finns flera bidrag att utnyttja som gör att kostnaden sjunker. Från och med den 1 januari 2018 kan privatpersoner bland annat sänka kostnaderna med 30 procent med hjälp av ett statligt solcellstöd ...

Fotovoltaisk (PV) kraftgenerering innebär att solljus omvandlas direkt till elektricitet med hjälp av solpaneler. Denna förnybara energikälla är ren och kostnadseffektiv, men den har en betydande begränsning. Den genererar endast ström när solen skiner.
Fotovoltaik är teknik som utnyttjar den fotovoltaiska effekten för direkt omvandling av ljusenergi från solen till elektrisk energi genom så kallade solceller, eller fotovoltaiska celler. På grund av den ökade efterfrågan av koldioxidneutrala energikällor under senare år har tillverkningen av och forskningen kring solceller och fotovoltaiska anläggningar ökat kraftigt.
