I-Gallium arsenide (GaAs) Ⅲ ~ V ibhetri edibeneyo esebenza kakuhle ukuya kuthi ga kwi-28%, izinto ezidibeneyo zeGaAs zinendawo efanelekileyo kakhulu yebhendi ye-optical, kunye nokusebenza kakuhle kokufunxa, ukumelana okunamandla kwimitha, ukungachukumisi ubushushu, ezifanelekileyo ekwenzeni ibhetri ye-single-junction esebenza kakuhle. Nangona kunjalo, ixabiso lezinto zeGaAs alibizi kakhulu, ngaloo ndlela lithintela ukuthandwa kweebhetri zeGaAs kakhulu.
Ibhetri yefilimu ebhityileyo yeCopper indium selenide (i-CIS ngamafutshane) ifanelekile ekuguqulweni kwe-photoelectric, akukho kwehla kwe-photoelectric, ukusebenza kakuhle kokuguqulwa kunye ne-polysilicon, njengoko kunjalo ngamaxabiso aphantsi, ukusebenza kakuhle kunye nokulula kwenkqubo kunye nezinye izibonelelo, ziya kuba yindlela ebalulekileyo yophuhliso lwexesha elizayo lweeseli zelanga. Ingxaki kuphela ngumthombo wezinto, ngenxa yokuba i-indium kunye ne-selenium zizinto ezinqabileyo, ngoko ke, uphuhliso lweebhetri ezinjalo luza kuthintelwa.
(3) iiseli zelanga zepolymer eziphilayo
Iipolymers zendalo endaweni yezinto ezingaphiliyo yindlela yophando yokwenziwa kweeseli zelanga. Njengoko izinto eziphilayo zinokuguquguquka okuhle, kulula ukuzenza, uluhlu olubanzi lwemithombo yezinto eziphathekayo, iindleko eziphantsi kunye nezinye izibonelelo, ngoko ke ukusetyenziswa okukhulu kwamandla elanga, ukubonelela ngombane ongabizi kubaluleke kakhulu. Nangona kunjalo, izinto eziphilayo zokulungiselela uphando lweeseli zelanga zisandula ukuqalisa, nokuba bubomi benkonzo, okanye ukusebenza kakuhle kwebhetri akunakuthelekiswa nezinto ezingaphiliyo, ngakumbi iibhetri zesilicon, nokuba ingaphuhliswa ibe yintsingiselo esebenzayo yemveliso, kodwa ikwafanele ihlolwe kuphando olongezelelweyo.
(4) iiseli zelanga ezi-nanocrystalline (iiseli zelanga eziveliswa yidayi)
Iiseli zelanga zeNano Ti02, amandla eekhemikhali ezikristale, ziphuhlisiwe ngokutsha, ngexabiso eliphantsi kunye nenkqubo elula kunye nokusebenza okuzinzileyo. Ukusebenza kwayo kwe-photovoltaic kuzinziswe ngaphezulu kwe-10%, iindleko zemveliso yi-1/5 ~ 1/10 kuphela yeeseli zelanga zesilicon, ixesha lokuphila linokufikelela kwiminyaka engaphezu kwama-20. Nangona kunjalo, ekubeni uphando nophuhliso lweeseli ezinjalo lusandula ukuqala, kuqikelelwa ukuba ziya kuza kancinci kwimarike kungekudala.
