Silicon solar cell

Silicon solar cells tau muab faib ua monocrystalline silicon solar cells, polycrystalline silicon nyias zaj duab xis hnub ci hlwb thiab amorphous silicon nyias zaj duab xis hnub ci.

Monocrystalline silicon solar cells muaj kev hloov pauv siab tshaj plaws thiab cov cuab yeej paub tab tshaj plaws. Kev hloov pauv siab tshaj plaws yog 24.7% hauv chav kuaj thiab 15% hauv kev tsim khoom loj (raws li xyoo 2011, 18%). Hauv kev siv loj thiab kev tsim khoom lag luam tseem muaj txoj haujlwm tseem ceeb, tab sis vim yog tus nqi siab ntawm monocrystalline silicon, nws yog qhov nyuaj los txo nws cov nqi, txhawm rau txuag cov ntaub ntawv silicon, kev txhim kho polycrystalline silicon zaj duab xis thiab amorphous silicon zaj duab xis. ua lwm txoj rau monocrystalline silicon solar cells.

Piv nrog monocrystalline silicon, polycrystalline silicon nyias zaj duab xis hnub ci hlwb muaj tus nqi qis thiab kev ua haujlwm siab dua li amorphous silicon nyias zaj duab xis hlwb, nrog rau qhov kev sim siab tshaj plaws ntawm kev hloov pauv ntawm 18% thiab kev lag luam nplai ntau lawm conversion efficiency ntawm 10% (raws li ntawm 2011, 17%). Yog li ntawd, polycrystalline silicon nyias-zaj duab xis hlwb 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 hauv qhov hnyav, siab hauv kev hloov dua siab tshiab, yooj yim rau cov khoom loj loj, thiab muaj peev xwm zoo. Txawm li cas los xij, vim tias qhov txo qis ntawm photoelectric efficiency tshwm sim los ntawm nws cov khoom, qhov kev ruaj ntseg tsis siab, uas cuam tshuam ncaj qha rau nws daim ntawv thov. Yog tias qhov teeb meem kev ruaj ntseg tuaj yeem daws tau ntxiv thiab qhov hloov pauv tau tuaj yeem txhim kho, ces amorphous silicon solar cells yog undoubtedly ib qho ntawm cov khoom tseem ceeb ntawm lub hnub ci.
