Txoj haujlwm tseem ceeb ntawm tes tau tsim hluav taws xob. Kev siv hluav taws xob hauv hluav taws xob tseem ceeb hauv kev ua lag luam yog crystalline silicon solar cell thiab nyias zaj duab xis solar cell. Ob leeg muaj lawv tus kheej zoo thiab qhov tsis zoo. Crystal silicon solar cells muaj cov cuab yeej siv qis dua, tab sis kev noj thiab khoom siv ntawm tus nqi yog siab, lub hnub ci vaj huam sib luag tab sis cov duab hluav taws xob photoelectric hloov dua siab tshiab kuj tseem siab, hnub ci vaj huam sib luag uas yog ntau dua haum rau lub zog tsim hluav taws xob hauv qab tshav ntuj; nyias-zaj duab xis hlwb hnub ci muaj cov cuab yeej siv khoom kim tus nqi, tab sis haus thiab roj teeb Tus nqi qis heev, tab sis cov duab hluav taws xob txuag hluav taws xob ntau dua li ib nrab ntawm cov ntawd ntawm cov khoom siv ua hluav taws xob silicon cell, lub hnub ci vaj huam sib luag tab sis lub teeb muaj zog tsawg heev, thiab nws tuaj yeem tsim hluav taws xob nyob rau hauv kev teeb pom kev zoo tib yam, lub hnub ci vaj huam sib luag xws li lub hnub ci cell ntawm lub tshuab xam zauv.
EVA ua haujlwm raws li saum toj no, hnub ci vaj huam sib luag tsuas yog ua ke thiab encapsulating lub zog hluav taws xob lub ntsiab lub cev thiab lub nraub qaum. Kev ua haujlwm rov qab, ntim, rwb thaiv tsev, hnub ci vaj huam sib luag tiv thaiv dej (feem ntau TPT, TPE thiab lwm yam khoom siv yuav tsum tiv taus kev laus, hnub ci vaj huam sib luag feem ntau cov tuam txhab ua lag luam muaj 25 xyoo lav, tempered iav, txhuas hlau feem ntau tsis muaj teeb meem, hnub ci vaj huam sib luag qhov tseem ceeb lus dag hauv seb puas muaj lub nraub qaum thiab silicone tuaj yeem ua tau raws li qhov yuav tsum tau ua.)
