Rau qhov tseem ceeb rau kev txo nqi photovoltaic thiab nce efficiency
Kev loj hlob ntawm kev tshawb fawb thiab thev naus laus zis tsis tuaj yeem ua yam tsis muaj kev pab ntawm lub zog. Tshwj xeeb tshaj yog nyob rau niaj hnub no' txoj kev loj hlob sai ntawm kev tshawb fawb thiab thev naus laus zis, kev tsim lub zog tauj dua tshiab tau dhau los ua kev pom zoo thoob ntiaj teb. Lub koom haum International Renewable Energy Agency (IRENA), nyob rau hauv kev pom ntawm kev txhim kho lub zog tauj dua tshiab, ntseeg hais tias qhov kev faib ua feem ntawm lub zog tauj dua tshiab hauv xyoo 2050 yuav ncav cuag 90%. Nrog rau kev txhim kho cov thev naus laus zis tshiab hauv kev lag luam photovoltaic, photovoltaic cell modules, kev tsim khoom, cov nqi teev, cov nqi raw khoom, thiab cov nqi tswj tau hloov mus rau qhov sib txawv. Ntawm lawv, kev tsim hluav taws xob tsim hluav taws xob ntawm photovoltaic modules tau nce los ntawm ib tus lej mus rau ntau dua 20%, thiab kev ua haujlwm ntawm kev sib npaug kuj tau raug txhim kho tas li, thiab tus nqi ntawm cov khoom siv hluav taws xob photovoltaic thiab cov nqi hluav taws xob tsis yog silicon tau poob. mus rau qhov sib txawv.
Tsav los ntawm lub teb chaws "cov pa roj carbon ncov thiab cov pa roj carbon nruab nrab", cov tuam txhab yuav ua li cas thiaj li txo tau tus nqi, nce kev ua tau zoo, thiab kev siv hluav taws xob zoo, pab photovoltaics ua lub zog loj thiab tsim lub ntiaj teb ntsuab thiab ntse?
Nyob rau hauv lub xyoo pua 21st, kev lag luam photovoltaic tau nkag mus rau lub sijhawm ntawm parity ntawm daim phiaj. Yog tias cov tuam txhab photovoltaic xav kom txo cov nqi ntxiv thiab ua kom muaj txiaj ntsig zoo, txo cov nqi photovoltaic thiab nce lub zog tsim hluav taws xob, ua kom cov tuam txhab photovoltaic uas twb muaj lawm, lawv yuav tsum tau them nyiaj rau kev ua haujlwm thiab kev saib xyuas cov nqi, kev tsim hluav taws xob puv sijhawm, thiab kev ua haujlwm siab. . Rau lub ntsiab lus tseem ceeb yog inverters, cov khoom siv ua haujlwm siab, cov roj teeb ua haujlwm siab, thiab cov nqi siv hluav taws xob.
Kev ua haujlwm thiab kev saib xyuas tus nqi
Kev ua haujlwm ntse thiab kev saib xyuas yog qhov tsim nyog los ua kom muaj kev tsim hluav taws xob zoo thiab txo cov nqi zog ntawm lub chaw nres tsheb fais fab, yog li txhawb kev txo cov nqi hluav taws xob. Sij hawm ntawm lub neej tag nrho lub zog tsim
Nrog rau kev tsim kho tshiab ntawm thev naus laus zis thiab txheej txheem, kev ua tiav ntawm cov khoom siv thiab kev sib koom ua ke tuaj yeem txuas ntxiv lub neej kev pabcuam rau 30 xyoo lossis ntau dua; Ntawm qhov tod tes, lub teeb tsis tshua muaj teb ntawm heterojunction thiab perovskite yuav ua rau cov sijhawm ua haujlwm tau zoo.
High efficiency inverter
High-efficiency inverters ua los ntawm cov ntaub ntawv xws li silicon carbide (SiC) thiab gallium nitride (GaN) tuaj yeem txo qhov tsis ua haujlwm ntawm cov khoom siv hluav taws xob, txo cov ntim thiab txuag nqi kev teeb tsa, thiab tseem tuaj yeem txo qhov loj ntawm lub inverter tshav kub dab dej (Vim GaN. thiab SiC muaj thermal conductivity zoo heev).
Cov khoom siv tau zoo
Muab ob npaug rau ob lub khob iav los yog cov khoom ntim tshiab tuaj yeem ua kom muaj zog ntxiv. High efficiency roj teeb Passivated emitter thiab rov qab cell technology roj teeb (PERC) Heterojunction roj teeb (HJT) Interdigital Back Contact Battery (IBC) Copper indium gallium selenide roj teeb (CIGS) Perovskite roj teeb (PSC) Silicon-based laminated roj teeb
Tus nqi system
Kev ntsuas xws li thinning ntawm cov pob zeb diamond hlau, qhov loj me, thiab txo qhov kev siv hluav taws xob ntawm lub drawbar yuav txo cov khoom siv thiab lub zog ntawm cov khoom.
Lub roj teeb efficiency tau hloov ntawm 20% mus rau 30%. Thaum txo tus nqi ib watt, nws kuj dilutes tus nqi ntawm cov av thiab cov nqi uas tsis yog cov khoom siv xws li cog kev tsim kho, kev txhawb nqa, khoom siv hluav taws xob, thiab cov nqi tswj.
Nyob rau hauv xyoo tas los no, lub xeev tau ua tiav cov phiaj xwm sib luag thiab cov phiaj xwm sib tw rau kev lag luam photovoltaic. Tsuas yog los ntawm kev txo cov nqi thiab nce kev ua tau zoo tuaj yeem ua cov tuam txhab photovoltaic muaj kev sib tw thiab sawv tawm ntawm ntau lub tuam txhab. Nrog rau kev xav tau ntawm lub zog tauj dua tshiab hauv ntau lub teb chaws, photovoltaics, uas yog qhov tseem ceeb hauv kev txhim kho lub zog tshiab, yog qhov tseeb tias kev lag luam photovoltaic yuav nce ntxiv rau yav tom ntej thiab dhau los ua txoj hauv kev tseem ceeb kom ua tiav" dual carbon" lub hom phiaj.
