3. PM (Peak Power)
Peak fais fab tuag (PM) yog lub zog siab tshaj plaws uas lub hnub ci vaj huam sib luag tuaj yeem tsim tau raws li cov qauv ntsuas (STC). STC yog hais txog cov txheej txheem uas siv los ntsuas kev ua haujlwm ntawm lub hnub ci vaj huam sib luag, xws li qhov kub thiab txias ntawm 25 degree, irradiance ntawm 1000 W / m2, thiab spectrum ntawm huab cua huab cua 1.5. PM yog ib qho tseem ceeb parameter uas qhia tau hais tias lub zog siab tshaj plaws ntawm lub hnub ci vaj huam sib luag tuaj yeem xa tuaj. Qhov siab dua PM tus nqi, lub zog ntau dua lub hnub ci vaj huam sib luag tuaj yeem tsim tau.
4. Imp (Qhov siab tshaj plaws tam sim no)
Lub zog siab tshaj plaws tam sim no (Imp) yog qhov tam sim no uas lub hnub ci vaj huam sib luag tsim tawm ntawm qhov chaw tso zis siab tshaj plaws. Nws yog ib qho tseem ceeb parameter uas qhia tias qhov siab tshaj plaws tam sim no lub hnub ci vaj huam sib luag tuaj yeem xa tuaj. Imp nyob ntawm ntau yam xws li qhov loj ntawm lub hnub ci vaj huam sib luag, theem ntawm irradiation nws tau txais, thiab qhov kub ntawm lub hnub ci vaj huam sib luag. Qhov siab dua tus nqi Imp, qhov siab dua qhov tam sim no lub hnub ci vaj huam sib luag tuaj yeem tsim tau.
5. Vmp (siab tshaj qhov hluav taws xob voltage)
Qhov siab tshaj plaws lub zog hluav taws xob (Vmp) yog qhov hluav taws xob uas lub hnub ci vaj huam sib luag tsim tawm ntawm qhov hluav taws xob siab tshaj plaws. Nws yog ib qho tseem ceeb parameter uas qhia txog qhov voltage theem ntawm lub hnub ci vaj huam sib luag ua hauj lwm ntawm lub siab tshaj plaws hwj chim tso zis. Vmp nyob ntawm ntau yam xws li qhov loj ntawm lub hnub ci vaj huam sib luag, theem ntawm irradiation nws tau txais, thiab qhov kub ntawm lub hnub ci vaj huam sib luag. Qhov siab dua tus nqi Vmp, qhov siab dua qhov voltage ntawm lub hnub ci vaj huam sib luag tuaj yeem tsim tau.
6. FF (Fill Factor)
Fill factor (FF) yog qhov piv ntawm lub zog siab tshaj plaws uas lub hnub ci vaj huam sib luag tuaj yeem xa mus rau cov khoom ntawm nws qhov qhib-circuit voltage thiab luv-circuit tam sim no. FF yog ib qho tseem ceeb uas qhia txog kev ua haujlwm ntawm lub hnub ci vaj huam sib luag. Qhov siab dua tus nqi FF, qhov ua tau zoo dua lub hnub ci vaj huam sib luag yog hloov lub hnub ci rau hauv hluav taws xob.
7. Kev ua haujlwm zoo (Efficiency)
Efficiency () yog qhov piv ntawm cov hluav taws xob hluav taws xob tso tawm ntawm lub hnub ci vaj huam sib luag rau lub hnub ci zog tawm tswv yim. Nws yog ib qho tseem ceeb parameter uas qhia tag nrho cov efficiency ntawm lub hnub ci vaj huam sib luag. Qhov siab dua tus nqi ua haujlwm, qhov ua tau zoo dua lub hnub ci vaj huam sib luag yog hloov lub hnub ci rau hauv hluav taws xob hluav taws xob.
Hauv kev xaus, lub hnub ci vaj huam sib luag yog tsim los ua haujlwm nyob rau hauv ntau yam kev mob, thiab lawv cov kev ua tau zoo raug soj ntsuam raws li ntau yam kev ua haujlwm. Cov tsis muaj xws li ISC, VOC, PM, Imp, Vmp, FF, thiab efficiency. Cov kev ntsuas no qhia txog kev ua haujlwm ntawm lub hnub ci vaj huam sib luag hauv kev tsim hluav taws xob hluav taws xob los ntawm lub hnub ci. Los ntawm kev nkag siab txog cov kev txwv no, peb tuaj yeem xaiv lub hnub ci zoo tshaj plaws rau peb daim ntawv thov tshwj xeeb thiab tsim kom muaj lub hnub ci zog zoo.
