| Description | Fotovoltaïese elektrisiteit (PV) is ’n gratis en skoon bron van hernubare energie wat oplossing bied vir baie sosio-ekonomiese probleme van beide Eerstewêreld- en Derdewêreldgemeenskappe. Grootskaalse invoering van PV word tans aan bande gelê deur die hoë koste van sonselle. Kristallynesilikon-sonselle domineer tans die wereldmark. Hierdie selle bestaan uit plat skywe suiwer Si met ’n p-n-voegvlak en die tegnologie is feitlik reeds vervolmaak met selle wat 'n doeltreffendheid van 24% lewer. Polikristallynesilikon- skywe se doeltreffendheid is effens laer, maar dit is meer koste-effektief. Die oplossing lê egter in die gebruik van dunlagieselle waar die materiaalkoste baie laag is en waar opskaling en massaproduksie ekonomies kompeterend gedoen kan word. PPhotovoltaic electricity (PV) is a free and clean source of renewable energy and presents a solution for many of the socio-economic problems of both first world and third world communities. Large-scale introduction of PV is currently hampered by the high cost of solar cells. At present crystalline silicon solar cells dominate the world market. These cells consist of flat wafers pure Si with a p-n junction and the technology is almost perfected with cell efficiencies of 24%. The efficiency of poly-crystalline wafers is somewhat lower but they are more cost effective. | |
