I-Photovoltaics inezinkambu ezimbili ezinkulu zokusetshenziswa: i-crystalline silicon kanye namafilimu amancane. Izinga lokuguqulwa kwamaseli elanga e-crystalline silicon liphezulu kakhulu, kodwa inqubo yokukhiqiza ingcolile, efanelekela kuphela izindawo zokukhanya okuqinile futhi ayikwazi ukukhiqiza ugesi ngaphansi kokukhanya okubuthakathaka. Amaseli elanga e-thin film, uma eqhathaniswa namanye amaseli elanga njenge-crystalline silicon, anezinzuzo eziningi njengezindleko zokukhiqiza eziphansi, ukusetshenziswa kwezinto eziluhlaza okuphansi, kanye nokusebenza kahle kokukhanya okubuthakathaka, okwenza kube lula ukufeza ukuhlanganiswa kwezakhiwo ze-thin film photovoltaic. Uma kuthathwa ibhethri le-Cadmium telluride thin film, ibhethri le-copper indium gallium selenium thin film kanye nefilimu encane ye-DLC njengezibonelo, ukusetshenziswa kwefilimu encane embonini ye-photovoltaic kwethulwa kafushane.
Amabhethri efilimu encane ye-Cadmium telluride (CdTe) anezinzuzo zokubekwa okulula, i-optical absorption coefficient ephezulu kanye nokusebenza okuzinzile. Ezisetshenzisweni zokukhiqiza ezisebenzayo, izingxenye zefilimu encane ye-CdTe ku-CdTe zizovalwa phakathi kwezingcezu ezimbili zengilazi, futhi ngeke kube nokukhishwa kwezimbiza zensimbi esindayo ekushiseni kwegumbi. Ngakho-ke, ubuchwepheshe bebhethri lefilimu encane ye-CdTe bunezinzuzo ezihlukile ekwakheni ukuhlanganiswa kwe-photovoltaic. Isibonelo, udonga lwekhethini le-photovoltaic lwesisekelo sobuhle bomdanso se-National Grand Theater, izindonga zemyuziyamu ye-photovoltaic, kanye nophahla lokukhanyisa lwesakhiwo konke kufezwa kusetshenziswa izingxenye zefilimu encane ye-CdTe.
Ubuchwepheshe be-copper steel selenium (CIGS) thin film solar cell kanye nezinto zokwakha zinamathuba amaningi okuthuthukiswa, futhi ukusebenza kwayo kuzinzile, okwenza kube uhlobo olusetshenziswa kakhulu lwebhethri le-thin film emkhakheni wokwakha. Ukusebenza kahle kwe-CIGS kwezimboni zamamojula amakhulu e-photovoltaic kuphezulu kakhulu, okwamanje cishe kusondela ekusebenzeni kahle kokuguqulwa kwamamojula e-crystalline silicon photovoltaic. Ngaphezu kwalokho, amabhethri e-CIGS thin film angenziwa amaseli e-photovoltaic aguquguqukayo.
Amafilimu amancane e-DLC nawo anezinhlelo zokusebenza eziningi emkhakheni we-photovoltaic
Ifilimu encane ye-DLC, njengefilimu yokuvikela evikela ukukhanya kwe-infrared yamadivayisi optical e-Ge, ZnS, ZnSe, kanye ne-GaAs, isifinyelele ezingeni elisebenzayo. Amafilimu amancane e-DLC nawo anesikhala esithile sokusetshenziswa kuma-laser anamandla aphezulu, futhi angasetshenziswa njengezinto zefasitela zama-laser anamandla aphezulu ngokusekelwe emkhawulweni wawo womonakalo ophezulu. Ifilimu ye-DLC nayo inemakethe ebanzi yokusetshenziswa kanye namathuba empilweni yansuku zonke, njengengilazi yewashi, amalensi engilazi yamehlo, izibonisi zekhompyutha, amafasitela emoto, kanye namafilimu okuvikela okuhlobisa esibukweni sangemuva.
