Hnub ci hlwb feem ntau suav nrog crystalline silicon cells thiab nyias -film cells, thiab lawv cov yam ntxwv txiav txim siab lawv cov xwm txheej tsis tuaj yeem hloov pauv hauv cov ntawv thov sib txawv.
This solar cell uses high-purity monocrystalline silicon rods as raw materials, with a purity requirement of 99.999 percent . In order to reduce production costs, solar-grade monocrystalline silicon rods are used for ground-based solar cells, and the material performance indicators have been relaxed. Some can also use the head and tail materials and waste monocrystalline silicon materials processed by semiconductor devices to be redrawn into monocrystalline silicon rods dedicated to solar cells. The single-crystal silicon rod is cut into slices, and the thickness of the slices is generally about 175 μm. The silicon wafer is formed, polished, cleaned and other processes to make the raw silicon wafer to be processed.
Kev suav fais fab ntawm Monocrystalline Silicon Solar Cells
Lub hnub ci hluav taws xob AC lub zog tsim hluav taws xob yog tsim los ntawm cov hnub ci vaj huam sib luag, cov tswj hwm, inverters thiab roj teeb; lub hnub ci DC lub zog tsim hluav taws xob tsis suav nrog lub inverter. Txhawm rau ua kom lub hnub ci hluav taws xob tsim hluav taws xob los muab lub zog txaus rau lub nra, nws yog ib qho tsim nyog yuav tsum xaiv txhua yam raws li lub zog ntawm cov khoom siv hluav taws xob. Siv 100W tso zis hluav taws xob thiab siv nws li 6 teev hauv ib hnub ua piv txwv los qhia txog txoj kev suav:
1. Ua ntej, xam cov watt- teev noj ib hnub (suav nrog qhov poob ntawm lub inverter): yog tias qhov kev hloov pauv ntawm lub inverter yog 90 feem pua, ces thaum lub zog tso zis yog 100W, lub zog tso zis yuav tsum yog 100W / 90 feem pua =111W; yog tias nws siv 5 teev ib hnub twg, kev siv hluav taws xob yog 111W5 teev=555Wh.
2. Xam lub hnub ci vaj huam sib luag: xam raws li lub hnub ci hnub ci lub sij hawm ntawm 6 teev, thiab xav txog qhov kev them nqi thiab qhov poob thaum lub sij hawm them nqi, cov zis hluav taws xob ntawm lub hnub ci vaj huam sib luag yuav tsum yog 555Wh / 6h / 70 feem pua =130 W. 70 feem pua ntawm cov uas yog lub zog tiag tiag siv los ntawm lub hnub ci vaj huam sib luag thaum lub sijhawm them nyiaj.
Test tej yam kev mob rau monocrystalline silicon solar cells
1. Txij li thaum lub zog tso zis ntawm lub hnub ci modules nyob ntawm cov yam ntxwv xws li hnub ci irradiance thiab hnub ci ntawm lub hnub ci kub, qhov ntsuas ntawm lub hnub ci cell modules yog ua raws li tus qauv (STC), uas txhais tau tias: huab cua zoo AM1.5, lub teeb siv 1000W / m2, kub 25 degree.
2. Nyob rau hauv cov xwm txheej no, lub siab tshaj plaws lub zog tso tawm los ntawm lub hnub ci cell module hu ua lub zog siab kawg. Feem ntau, lub zog siab tshaj plaws ntawm lub module feem ntau yog ntsuas los ntawm lub hnub ci simulator. Lub ntsiab yam tseem ceeb uas cuam tshuam rau kev ua tau zoo ntawm lub hnub ci modules yog load impedance, hnub ci siv, kub, duab ntxoov ntxoo thiab lwm yam.
Monocrystalline silicon solar cells yog cov hnub ci hnub ci uas siv siab -purity monocrystalline silicon rods ua raw cov ntaub ntawv thiab tam sim no yog qhov ceev tshaj plaws hnub ci hlwb. Nws cov qauv thiab cov txheej txheem ntau lawm tau ua tiav, thiab cov khoom tau siv dav hauv qhov chaw thiab hauv av.
