Solar cells hom tshooj 1

Hnub ci hnub ci tau tsim los rau tiam thib peb, uas thawj tiam yog monocrystalline silicon hnub ci hlwb, tiam thib ob yog amorphous silicon thiab polycrystalline silicon hnub ci hlwb, thiab tiam thib peb yog tooj liab-steel-gallium-selenide (CIGS) ua tus sawv cev ntawm nyias zaj duab xis compound solar cells.
Raws li kev npaj cov roj teeb uas siv cov khoom sib txawv, lub hnub ci tuaj yeem muab faib ua pawg hauv qab no.

Silicon solar cells tau muab faib ua monocrystalline silicon hnub ci hlwb, polycrystalline silicon nyias zaj duab xis hnub ci thiab amorphous silicon nyias-zaj duab xis hnub ci ntawm peb hom.
Monocrystalline silicon solar cells muaj kev hloov pauv siab tshaj plaws thiab cov cuab yeej paub tab tshaj plaws. Qhov kev hloov pauv siab tshaj plaws hauv chav kuaj yog 23% nplai, thiab qhov ua tau zoo hauv kev tsim khoom yog 15%, uas tseem yog tus thawj coj hauv kev siv loj thiab kev tsim khoom. Txawm li cas los xij, vim yog tus nqi siab ntawm monocrystalline silicon, nws yog ib qho nyuaj rau txo nws cov nqi, thiaj li yuav txuag tau cov ntaub ntawv silicon, kev txhim kho ntau yam khoom silicon nyias zaj duab xis thiab amorphous silicon nyias zaj duab xis ua lwm txoj hauv kev rau monocrystalline silicon solar cells.
Polycrystalline silicon nyias zaj duab xis hnub ci hlwb thiab monocrystalline silicon hnub ci hlwb, tus nqi yog tsawg, thaum lub efficiency yog siab tshaj amorphous silicon nyias-zaj duab xis hnub ci hlwb, lub siab tshaj plaws conversion efficiency ntawm nws lub chaw soj nstuam yog 18%, lub conversion efficiency ntawm industrial-scale ntau lawm yog 10%. Yog li ntawd, polycrystalline silicon nyias zaj duab xis hnub ci cell yuav sai sai no dominate lub hnub ci cell lag luam.
Amorphous silicon nyias zaj duab xis hnub ci hlwb yog tus nqi qis, lub teeb yuag, kev hloov pauv siab, yooj yim rau huab hwm coj ntau lawm, muaj peev xwm zoo. Txawm li cas los xij, txwv tsis pub los ntawm nws cov khoom siv-induced photoelectric efficiency poob qis, stability tsis siab, ncaj qha cuam tshuam rau nws cov tswv yim siv. Yog tias peb tuaj yeem daws qhov teeb meem kev ruaj ntseg ntxiv thiab txhim kho tus nqi hloov pauv, ces amorphous silicon solar cells yog undoubtedly lub ntsiab kev loj hlob ntawm lub hnub ci hlwb ntawm cov khoom!
(2) Multi-compound nyias zaj duab xis solar cells
Multi-compound nyias zaj duab xis hnub ci cell cov ntaub ntawv rau inorganic ntsev, xws li gallium arsenide tebchaw, cadmium sulfide, cadmium sulfide thiab tooj liab kaw selenium nyias zaj duab xis roj teeb.
Cadmium sulfide, cadmium telluride polycrystalline thin-film solar cell efficiency yog siab dua cov uas tsis yog-pin silicon nyias zaj duab xis hnub ci hlwb, tus nqi qis dua monocrystalline silicon hnub ci hlwb, thiab kuj yog ib qho yooj yim rau loj-scale ntau lawm, tab sis vim cadmium muaj ib tug siab toxicity, yuav ua rau mob loj pollution ntawm lub ntiaj teb no lub tswv yim ntawm solar hlwb.
