Lisele tsa photovoltaic li ne li sebelisoa haholo-holo sebakeng, sesole le masimo a mang a photon ea pele - Lilemong tse 20 tse fetileng, litšenyehelo tsa lisele tsa photovoltaic li oele ka mokhoa o tsotehang ho ntšetsa pele sebaka sa lehaha jump photovoltaic ka mefuta e mengata ea likopo tsa lefats'e. Qetellong ea 2019, kakaretso hlomamisa bokgoni ba letsatsi PV lefatšeng ka bophara fihla 616GW, 'me ho lebeletsoe ho fihla 50% ea matla a lefats'e ka bophara matla a ho hlahisa matla ka 2050. Ka lebaka la photovoltaic semiconductor lintho tse bonahalang ka absorption ea leseli haholo-holo le hlaha ka microns tse seng kae ho makholo a microns botenya ba lintho tse bonahalang le bohlokoa haholo holim'a semicondu seleng ea thekenoloji, ka lebaka la semicondu semiconductor ea bohlokoa haholo. e na le lisebelisoa tse ngata tse fapaneng ha ho etsoa motlakase oa letsatsi.
Lisele tsa photovoltaic tse tsoetseng pele li oela likarolong tse peli tse kholo: lisele tsa letsatsi tsa crystalline silicon le lisele tse tšesaane tsa letsatsi la filimi. Theknoloji ea morao-rao ea crystalline silicon cell cell e kenyelletsa theknoloji ea passivated emitter le backside cell (PERC), theknoloji ea heterojunction (HJT), theknoloji ea emitter backside full diffusion (PERT), le thekenoloji ea tunneled oxide passivated contact (Topcon). Mesebetsi ea lifilimi tse tšesaane ka liseleng tsa silicon tsa crystalline haholo-holo li kenyelletsa ho feta, ho fokotsa ho bonahatsa, P / N doping, le conductivity. Litheknoloji tse ka sehloohong tsa betri ea filimi e tšesaane li kenyelletsa cadmium telluride, copper indium gallium selenide, le chalcogenide. Lifilimi tse tšesaane li sebelisoa haholo e le lera le monyang khanya, lera la conductive, joalo-joalo ho tsona. Ho lokisoa ha lifilimi tse tšesaane liseleng tsa photovoltaic hangata ho sebelisoa mefuteng e fapaneng ea theknoloji ea ho roala vacuum.
