Tshooj 1 ntawm cov hlwb hnub ci

Cov hlwb 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-hlau-gallium-selenide (CIGS) ua tus sawv cev ntawm cov hlwb nyias zaj duab xis hnub ci.
Raws li kev npaj lub roj teeb siv cov ntaub ntawv sib txawv, cov hlwb hnub ci tuaj yeem muab faib ua pawg hauv qab no.

Cov roj teeb hnub ci silicon muab faib ua peb hom: monocrystalline silicon solar cells, polycrystalline silicon thin-film solar cells thiab amorphous silicon thin-film solar cells.
Cov roj teeb hnub ci monocrystalline silicon muaj qhov ua tau zoo tshaj plaws thiab cov thev naus laus zis laus tshaj plaws. Qhov ua tau zoo tshaj plaws hauv chav kuaj yog 23%, thiab qhov ua tau zoo hauv kev tsim khoom yog 15%, uas tseem tswj hwm hauv cov ntawv thov loj thiab kev tsim khoom lag luam. Txawm li cas los xij, vim yog tus nqi siab ntawm monocrystalline silicon, nws nyuaj rau txo nws cov nqi, txhawm rau txuag cov ntaub ntawv silicon, kev tsim cov yeeb yaj kiab nyias nyias ntau yam thiab cov yeeb yaj kiab nyias nyias amorphous silicon ua lwm txoj hauv kev rau cov roj teeb hnub ci monocrystalline silicon.
Cov roj teeb hnub ci polycrystalline silicon nyias zaj duab xis thiab cov roj teeb hnub ci monocrystalline silicon, tus nqi qis, thaum qhov ua tau zoo dua li cov roj teeb hnub ci amorphous silicon nyias zaj duab xis, qhov ua tau zoo tshaj plaws ntawm nws lub chaw soj nstuam yog 18%, qhov ua tau zoo ntawm kev tsim khoom lag luam yog 10%. Yog li ntawd, cov roj teeb hnub ci polycrystalline silicon nyias zaj duab xis yuav sai sai no tswj hwm kev lag luam roj teeb hnub ci.
Cov roj teeb amorphous silicon nyias zaj duab xis hnub ci yog pheej yig, lub teeb yuag, kev hloov pauv siab, yooj yim rau kev tsim khoom loj, thiab muaj peev xwm loj heev. Txawm li cas los xij, vim nws cov khoom siv ua rau muaj kev poob qis ntawm photoelectric efficiency, kev ruaj khov tsis siab, cuam tshuam ncaj qha rau nws cov kev siv. Yog tias peb tuaj yeem daws qhov teeb meem ruaj khov ntxiv thiab txhim kho qhov hloov pauv, ces cov roj teeb amorphous silicon hnub ci yog qhov tseem ceeb ntawm kev tsim cov roj teeb hnub ci!
(2) Cov roj teeb hnub ci uas muaj ntau yam sib xyaw ua ke
Cov ntaub ntawv ntawm lub roj teeb hnub ci uas muaj ntau yam sib xyaw ua ke rau cov ntsev inorganic, suav nrog cov tshuaj gallium arsenide, cadmium sulfide, cadmium sulfide thiab tooj liab raug kaw selenium zaj duab xis roj teeb.
Cadmium sulfide, cadmium telluride polycrystalline nyias-zaj duab xis hnub ci cell ua haujlwm tau zoo dua li cov tsis-pin silicon nyias-zaj duab xis hnub ci cell, tus nqi qis dua li monocrystalline silicon hnub ci cell, thiab kuj yooj yim rau kev tsim khoom loj, tab sis vim yog cadmium muaj tshuaj lom ntau, yuav ua rau muaj kuab paug loj rau ib puag ncig, yog li nws tsis yog lwm txoj hauv kev zoo tshaj plaws rau lub cev pin ntawm silicon hnub ci cell.
