Izinzuzo kanye nokungalungi kwamaseli elanga anefilimu emincane

Amaseli elanga acwebezelayo asetshenziswa kakhulu ezindaweni zokugcina izithombo zezolimo ze-photovoltaic kanye nezindawo ze-photovoltaic ezidinga ukudluliswa kokukhanya. Ingabe uyazi ukuthi yiziphi izinzuzo kanye nokubi amaseli mncane-film elanga? Mingaki iminyaka le solar panel enefilimu elincanyana?

Njengamanje, amangqamuzana elanga akhona ayifilimu emincane emincane ahlanganisa ikakhulukazi: amaseli elanga e-cadmium telluride amancane-ifilimu, i-copper indium gallium selenide amaseli elanga amancane efilimu, kanye namaseli elanga elanga amorphous silicon thin-film.

1. Izinzuzo zamaseli elanga anefilimu elincanyana

(1) Inani lokukhanya kwelanga elinezinga eliphezulu lokumunca.

I-GaAs ingeyezinto ze-semiconductor ezihlanganisiwe ze-III-V, futhi igebe layo lamandla lingu-1.4eV, okuyinani nje lezinga eliphezulu lokumunca ukukhanya kwelanga, elifaneleka kakhulu ukumataniswa ne-solar spectrum.

(2) Ukumelana nokushisa okuphezulu.

Ngaphansi kwesimo esingu-250 ° C, ukusebenza kokuguqulwa kwesithombe sikagesi kusekuhle kakhulu, futhi ukusebenza kahle kwayo okuphezulu kakhulu kokuguqulwa kwesithombe sikagesi cishe kungama-30%, okulungele ngokukhethekile izinga lokushisa eliphezulu lokugxilisa amaseli elanga efilimu emincane.

(3) Izindleko eziphansi.

Ukusebenzisa ama-wafers e-silicon njengama-substrates, indlela ye-heteroepitaxial yobuchwepheshe be-MOCVD iyindlela ethembisayo yokunciphisa izindleko zamaseli e-GaAs.

2. Ukungalungi kwamangqamuzana elanga anefilimu elincane

(1) Ukonakala kalula.

Indlela yokukhula yamangqamuzana elanga anefilimu emincane inquma ukuthi amangqamuzana elanga anefilimu elincanyana athambekele ekubeni ne-deliquescent, ngakho-ke ukumelana namanzi kwezinto eziqukethe i-fluorine edingekayo ukuze kuhlanganiswe amangqamuzana elanga anefilimu elincanyana cishe kunamandla izikhathi ezingu-9 kunamaseli e-silicon e-crystalline.

(2) Ukuncipha kwesithombe.

Ukuncishiswa kwamaseli elanga acwebile kucishe kube ngu-30%.

(3) Ukusebenza kahle kokuguqulwa kwamaseli elanga anefilimu elincanyana kuphansi.

Ngenxa yokusebenza kahle kakhulu kokuguqulwa kwamaseli elanga elanga, iningi lawo livela emikhiqizweni ye-elekthronikhi emincane futhi eguquguqukayo.

(4) I-Cadmium telluride entweni yokukhiqiza iwubuthi.

I-Cadmium iwubuthi obuyingozi obunqwabelana ochungechungeni lokudla njenge-mercury, okuphambene nomqondo wokuhambisana nemvelo, ukuphepha nokungabi nobuthi. Izikhungo eziningi namalabhorethri zifuna ezinye izindlela ezivumelana nemvelo, ezisebenza kahle kakhulu, futhi abakhiqizi belanga bahlola izindlela zokubuyisa nokuphinda basebenzise izinto eziqukethe i-cadmium ukuze baxazulule izinkinga zemvelo.
