I te tīmatanga o te ao photon, i whakamahia nuitia ngā pūtau photovoltaic i te wāhi mokowā, i te ope taua me ētahi atu mara – I ngā tau 20 kua pahure ake nei, kua tino heke te utu o ngā pūtau photovoltaic hei whakatairanga i te peke ana mokowā photovoltaic i roto i te whānuitanga o ngā tono o te ao. I te mutunga o te tau 2019, kua eke te katoa o te kaha tāuta o te PV solar puta noa i te ao ki te 616GW, ā, e matapaetia ana ka eke ki te 50% o te katoa o te kaha whakaputa hiko o te ao i te tau 2050. Nā te mea ko te rauemi semiconductor photovoltaic te nuinga o te wā ka mimiti i te mārama i roto i te whānuitanga matotoru o te torutoru microns ki te rau microns me te mahi mata o te rauemi semiconductor he mea tino nui, nō reira he whānuitia ngā tono o te hangarau kiriata angiangi korehau i roto i te hanga hiko solar.
E rua ngā wāhanga matua o ngā pūtau photovoltaic ahumahi: ngā pūtau solar silicon crystalline me ngā pūtau solar kiriata angiangi. Ko ngā hangarau pūtau silicon crystalline hou ko te hangarau passivated emitter and backside cell (PERC), te hangarau heterojunction (HJT), te hangarau passivated emitter backside full diffusion (PERT), me te hangarau pūtau tunneled oxide passivated contact (Topcon). Ko ngā mahi a ngā kiriata angiangi i roto i ngā pūtau silicon crystalline ko te passivation, te whakaiti whakaata, te doping P/N, me te kawe hiko. Ko ngā hangarau pākahiko kiriata angiangi matua ko te cadmium telluride, te copper indium gallium selenide, me te chalcogenide. Ko ngā kiriata angiangi te nuinga o te wā e whakamahia ana hei paparanga mimiti mārama, hei paparanga kawe hiko, me ētahi atu i roto i a rātou. Ko te whakarite i ngā kiriata angiangi i roto i ngā pūtau photovoltaic he mea whakamahi pinepine i roto i ngā momo hangarau paninga korehau.
