Qhov kev faib ua feem ntawm dual-iav modules tau nce xyoo los ntawm xyoo. Raws li CPIA cov ntaub ntawv, kev lag luam sib faib ntawm ib sab iav photovoltaic modules hauv kuv lub teb chaws xyoo 2020 yog kwv yees li 70%, thiab kev lag luam feem ntawm ob sab iav photovoltaic modules yog kwv yees li 30%. Vim yog qhov zoo ntawm kev hloov pauv ntawm photoelectric siab thiab qeeb qis ntawm ob chav iav modules, nws xav tias ob chav iav modules yuav maj mam dhau los ua lub ntsiab ntawm kev lag luam thaum lub sij hawm" 14th Tsib Xyoo Plan" lub sij hawm, uas kuj txhais tau hais tias qhov kev thov rau photovoltaic iav yuav nce ho.
Qhov kev faib ua feem ntawm qhov loj-loj silicon wafers tau maj mam nce. Tam sim no, muaj ntau qhov ntau thiab tsawg ntawm silicon wafer nyob rau hauv kev ua lag luam, feem ntau me dua 166mm, 166mm, 182mm, 210mm, thiab lwm yam. Raws li CPIA cov ntaub ntawv, silicon wafers me dua 166mm yuav yog lub lag luam loj hauv xyoo 2020. Txawm li cas los xij, txij li qhov loj-loj silicon wafers tuaj yeem txo cov nqi tsim khoom ntawm silicon wafers, nws xav tias silicon wafers yuav loj hlob mus rau qhov loj me nyob rau hauv lub neej yav tom ntej, thiab qhov loj ntawm silicon wafers loj, yuav tsum tau photovoltaic ntau iav.
Qhov tsawg-thickness photovoltaic iav yuav yog yav tom ntej sib. Tam sim no, lub thickness ntawm cov iav photovoltaic ntawm kev ua lag luam tau muab faib ua tsawg dua 2.5mm, 2.8mm, 3.2mm thiab lwm yam. Raws li CPIA cov ntaub ntawv, kev lag luam sib koom ntawm 3.2 hli photovoltaic iav modules yog qhov siab tshaj plaws hauv xyoo 2020, kwv yees li 70%, thaum lub lag luam feem ntawm photovoltaic iav yog tsawg dua 2.5 hli, uas yog siv rau ob chav iav modules, tsawg dua 30. %. Lub thickness ntawm 2.5 hli photovoltaic iav muaj ntau yam zoo, nrog rau lub teeb transmittance siab, uas tuaj yeem txhim kho photoelectric conversion efficiency, thiab lub teeb yuag, uas tuaj yeem txo cov nqi tsheb thauj mus los thiab kev teeb tsa. Nws cia siab tias yuav dhau los ua tus qauv tseem ceeb yav tom ntej.
