Maselo a Photovoltaic ankagwiritsidwa ntchito makamaka mumlengalenga, asilikali ndi madera ena oyambirira photon - M'zaka zapitazi za 20, mtengo wa maselo a photovoltaic wagwa kwambiri kulimbikitsa mlengalenga phanga kulumpha photovoltaic mu ntchito zosiyanasiyana padziko lonse. Kumapeto kwa 2019, okwana anaika mphamvu ya dzuwa PV padziko lonse anafika 616GW, ndipo akuyembekezeka kufika 50% ya dziko okwana mphamvu m'badwo ndi 2050. Chifukwa photovoltaic semiconductor zakuthupi pa mayamwidwe kuwala makamaka imapezeka mu ma microns mazana mazana microns makulidwe a zinthu ndi semicondu filimu makulidwe a zinthu zofunika kwambiri ndi semicondu filimu yopyapyala. ali ndi ntchito zosiyanasiyana popanga magetsi a dzuwa.
Maselo a photovoltaic opangidwa ndi mafakitale amagwera m'magulu awiri akuluakulu: maselo a crystalline silicon solar cell ndi mafilimu ochepa kwambiri a dzuwa. Matekinoloje apamwamba kwambiri a crystalline silicon cell cell amaphatikiza ukadaulo wa passivated emitter ndi backside cell (PERC), ukadaulo wa heterojunction (HJT), ukadaulo wa passivated emitter backside full diffusion (PERT), ndi ukadaulo wa tunneled oxide passivated contact (Topcon). Ntchito zamakanema oonda m'maselo a silicon crystalline makamaka amaphatikiza kukhudzika, kuchepetsa kuwunikira, P/N doping, ndi conductivity. Tekinoloje yayikulu ya batri yamakanema amaphatikizapo cadmium telluride, copper indium gallium selenide, ndi chalcogenide. Mafilimu woonda amagwiritsidwa ntchito ngati wosanjikiza wopepuka, wosanjikiza, ndi zina. Kukonzekera kwa mafilimu oonda m'maselo a photovoltaic amagwiritsidwa ntchito nthawi zambiri mumitundu yosiyanasiyana ya teknoloji yokutira vacuum.
