Hom ntawm hnub ci photovoltaic panels
Nyob zoo txhua tus, hnub ci tsim hluav taws xob tseem hu ua photovoltaic zog tsim. Tus nqi nkag mus tam sim no ntau dua li ntawm 15 xyoo dhau los! Tsuas yog siv tus nqi kaum tawm daus las ib watt 15 xyoo dhau los los ua cov tsev neeg ib txwm muaj thiab kev lag luam hauv Suav teb Kuv tsis tuaj yeem hu ncaj qha ~~ Tab sis tom qab National Development and Reform Commission pib lub kilowatt-teev nyiaj pab, tus nqi ntawm photovoltaics tau poob qis, thiab Tuam Tshoj txoj kev lag luam photovoltaic kuj tau pib ua kom muaj kev loj hlob. Nyob rau tib lub sijhawm, kev tsim hluav taws xob photovoltaic kuj tau tsim los rau: cov chaw loj hauv paus hauv paus hauv av, cov chaw faib hluav taws xob me me, thiab cov tsev neeg me uas faib cov chaw siv hluav taws xob. Tau kawg, yam peb paub tshaj plaws yog tsev faib hluav taws xob chaw nres tsheb. Tau kawg, ntau tsev neeg uas tsis tau teeb tsa nws ntawm no kuj tseem pib txav mus! Tab sis nyob rau hauv lub ntsej muag ntawm ntau yam ntawm cov khoom vaj huam sib luag hnub ci thiab hom sib txawv ntawm cov hnub ci vaj huam sib luag, peb yuav xaiv li cas? Cov kws kho mob hauv qab no yuav muab rau koj kev paub txog science:
Ua ntej tshaj plaws, peb xub nkag siab tias tam sim no daim ntawv thov tseem ceeb ntawm cov hnub ci vaj huam sib luag ntawm lub khw tau muab faib ua: 1. Monocrystalline solar panels. 2. Polycrystalline solar panels. 3. Nyias zaj duab xis solar panels. Qhov sib txawv ntawm peb ntawm lawv yog:
1. Monocrystalline silicon
Kev hloov pauv hluav taws xob ua haujlwm tau zoo ntawm monocrystalline silicon solar cells yog li 18%, thiab siab tshaj yog 24%. Qhov no yog qhov ua tau zoo tshaj plaws hloov hluav taws xob hloov pauv ntawm txhua hom hnub ci cell, tab sis tus nqi tsim khoom yog siab heev. Vim tias monocrystalline silicon feem ntau siv cov iav tempered thiab tsis muaj dej Cov kua nplaum tau ntim, yog li nws ruaj thiab muaj lub neej ua haujlwm ntev txog 25 xyoos.
2. Polysilicon
Cov txheej txheem tsim khoom ntawm polycrystalline silicon solar cells zoo ib yam li ntawm monocrystalline silicon solar cells, tab sis kev hloov pauv hluav taws xob ua kom zoo ntawm polycrystalline silicon solar cells yuav tsum tau txo ntau, thiab nws qhov kev hloov pauv photoelectric yog li 16%. Hais txog tus nqi tsim khoom, nws pheej yig dua li monocrystalline silicon solar cells, cov khoom siv tau yooj yim los tsim, kev siv hluav taws xob tau txais kev cawmdim, thiab tag nrho cov nqi tsim khoom qis dua, yog li nws tau tsim hauv qhov loj. Hais txog tus nqi ua tau zoo, monocrystalline silicon solar cells zoo dua me ntsis.
3. Amorphous silicon
Amorphous silicon solar cell yog ib yam tshiab ntawm daim nyias nyias zaj duab xis hnub ci uas tau tshwm sim xyoo 1976. Nws txawv ntawm monocrystalline silicon thiab polycrystalline silicon solar cells. Cov txheej txheem tau yooj yim heev, kev siv cov khoom siv silicon tsawg, thiab kev siv hluav taws xob qis dua. Qhov kom zoo dua yog tias nws tuaj yeem tsim hluav taws xob hauv qhov pom kev qis. Txawm li cas los xij, qhov teeb meem tseem ceeb ntawm amorphous silicon solar cells yog qhov kev hloov pauv hluav taws xob tsawg tsawg, qib thoob ntiaj teb tau nce txog 10%, thiab nws tsis ruaj khov txaus. Raws li lub sijhawm dhau mus, nws txoj kev hloov pauv tau hloov pauv.
