Hnub ci Photovoltaic iav txheej txheem

Hnub ci photovoltaic iav yog ib hom iav uas siv los tsim cov hnub ci vaj huam sib luag. Nws yog tsim tshwj xeeb los hloov lub hnub ci rau hauv hluav taws xob thiab yog ib qho tseem ceeb ntawm lub hnub ci hluav taws xob tsim hluav taws xob. Kev tsim cov iav photovoltaic suav nrog ntau theem, los ntawm kev npaj cov khoom siv raw mus rau qhov kawg ntawm cov iav panels.

Thawj kauj ruam hauv kev tsim cov iav photovoltaic yog kev npaj cov khoom siv raw. Cov khoom xyaw tseem ceeb siv hauv kev tsim cov iav photovoltaic yog silica xuab zeb, dej qab zib tshauv, thiab limestone. Cov ntaub ntawv no yog tov nyob rau hauv txoj cai proportions thiab melted nyob rau hauv high kub nyob rau hauv lub cub tawg. Cov iav melted ces txias maj mam los tsim ib qho chaw tiaj tus, du nto uas tsis muaj impurities.

Tom qab lub khob npaj, nws yog ces coated nrog ib tug nyias txheej ntawm semiconductor khoom. Cov khoom no feem ntau yog ua los ntawm silicon thiab yog lub luag haujlwm rau hloov lub hnub ci rau hauv hluav taws xob. Cov khoom siv semiconductor yog siv rau iav nto siv cov txheej txheem hu ua "chemical vapor deposition" (CVD).

Thaum cov txheej txheem semiconductor tau thov, lub iav yog coated nrog ib txheej conductive. Cov txheej no feem ntau yog ua los ntawm cov hlau, xws li txhuas lossis nyiaj, thiab ua haujlwm rau cov hluav taws xob tsim los ntawm txheej semiconductor. Cov txheej txheem conductive yog siv los ntawm kev siv cov txheej txheem hu ua "sputtering," uas cuam tshuam nrog kev siv cov khoom siv hluav taws xob siab kom tso cov hlau mus rau qhov chaw ntawm lub khob.

Thaum kawg, cov iav tiav yog txiav thiab sib sau ua ke rau hauv cov hnub ci vaj huam sib luag. Cov panels raug kuaj xyuas kom ntseeg tau tias lawv ua tau raws li cov qauv tsim nyog rau kev ua tau zoo, ua haujlwm ntev, thiab kev nyab xeeb. Tom qab ntawd cov panels tau ntim thiab xa mus rau cov neeg siv khoom thoob plaws ntiaj teb.

Hauv kev xaus, kev tsim cov hnub ci photovoltaic iav suav nrog cov thev naus laus zis thev naus laus zis thiab kev tswj hwm kev ntsuas zoo. Nrog rau qhov kev thov rau lub zog tauj dua tshiab tau nce siab, lub hnub ci kev lag luam yuav tsum tau loj hlob ntxiv, muab cov hauv kev tshiab rau kev tsim kho tshiab thiab kev nce qib ntawm kev siv thev naus laus zis. Raws li peb txuas ntxiv mus rau txoj hauv kev ntawm lub zog ruaj khov, kev tsim cov iav photovoltaic yuav ua lub luag haujlwm tseem ceeb hauv kev hloov mus rau kev huv huv, muaj kev nyab xeeb dua yav tom ntej.
