Ua hoʻohana nui ʻia nā cell photovoltaic ma ka lewa, ka pūʻali koa a me nā ʻoihana ʻē aʻe i ka wā mua o ka photon - I nā makahiki he 20 i hala iho nei, ua hāʻule nui ke kumukūʻai o nā cell photovoltaic e hoʻolaha i ka lele ʻana o ka lewa photovoltaic ma kahi ākea o nā noi honua. I ka hopena o 2019, ua hōʻea ka nui o ka mana i hoʻokomo ʻia o ka PV solar ma ka honua holoʻokoʻa i 616GW, a manaʻo ʻia e hiki i ka 50% o ka nui o ka mana hana mana o ka honua ma ka makahiki 2050. Ma muli o ka mea semiconductor photovoltaic ma ka omo ʻana o ka mālamalama e kū nui ana ma kekahi mau microns a i nā haneli o microns ka mānoanoa a me ka hana ʻana o ka ʻili o ka mea semiconductor o ke kelepona, no laila he ākea ka nui o nā noi o ka ʻenehana kiʻiʻoniʻoni vacuum i ka hana ʻana i ka uila solar.
ʻO nā cell photovoltaic ʻoihana i hāʻule i ʻelua mau māhele nui: nā cell solar silicon crystalline a me nā cell solar film lahilahi. ʻO nā ʻenehana cell silicon crystalline hou loa e komo pū ana me ka ʻenehana passivated emitter a me backside cell (PERC), ka ʻenehana heterojunction (HJT), ka ʻenehana passivated emitter backside full diffusion (PERT), a me ka ʻenehana cell tunneled oxide passivated contact (Topcon). ʻO nā hana o nā kiʻiʻoniʻoni lahilahi i loko o nā cell silicon crystalline e komo pū ana me ka passivation, ka hoʻemi ʻana i ka reflection, P/N doping, a me ka conductivity. ʻO nā ʻenehana pākahiko thin-film nui e komo pū ana me ka cadmium telluride, copper indium gallium selenide, a me ka chalcogenide. Hoʻohana nui ʻia nā kiʻiʻoniʻoni lahilahi ma ke ʻano he papa omo mālamalama, papa conductive, a me nā mea ʻē aʻe i loko o lākou. ʻO ka hoʻomākaukau ʻana o nā kiʻiʻoniʻoni lahilahi i loko o nā cell photovoltaic e hoʻohana pinepine ʻia i nā ʻano ʻenehana uhi vacuum like ʻole.
