Raws li txoj kev npaj "ob lub carbon", Tuam Tshoj txoj kev lag luam photovoltaic (PV) tau ua tiav kev tsim kho tshiab zoo kawg nkaus, txhawb kev tsim cov thev naus laus zis cell ua haujlwm tau zoo thiab ntau yam kev siv. Xyoo 2024, lub PV sector tab tom pom kev nce ntxiv hauv cov thev naus laus zis tshiab xws li HJT, BC, thiab perovskite, qhia txog lub sijhawm tshiab ntawm kev nce qib thev naus laus zis.
HJT Tshuab
Cov thev naus laus zis Heterojunction (HJT) muaj kev ua haujlwm zoo heev, kev tsim hluav taws xob bifacial, cov coefficients kub qis, thiab txo qhov puas tsuaj. Nyob rau hauv xyoo tas los no, kev tshawb pom tshiab hauv cov ntaub ntawv upstream tau txo cov nqi ntau heev. Piv txwv li, KEEs 'kev muab khoom ruaj khov ntawm cov nyiaj-coated tooj liab paste tau daws cov teeb meem nqi, thaum cov thawj coj hauv kev lag luam siv cov thev naus laus zis patented xws li 0BB cells thiab ultra-thin silicon wafers rau kev tsim khoom loj. Cov kws tshuaj ntsuam xyuas kwv yees tias HJT txoj kev loj hlob yuav rov kho dua tshiab kev lag luam PV, tsav tsheb txhim kho peev xwm thiab txhawb nqa nws qhov kev sib tw thoob ntiaj teb.
BC Tshuab
Cov hlwb Back Contact (BC) raug suav hais tias yog qhov zoo tshaj plaws ntawm kev ua haujlwm ntawm crystalline silicon. Lawv txoj kev tsim qauv pem hauv ntej uas tsis muaj grid ua rau ob qho tib si zoo nkauj thiab lub zog tso zis. BC thev naus laus zis sib koom ua ke nrog lwm hom hlwb xws li TOPCon thiab HJT, ua rau muaj kev ua haujlwm zoo dua. Cov thawj coj hauv kev lag luam xws li LONGi thiab Aiko tau tsim cov khoom BC, nrog cov kws tshaj lij kwv yees tias BC feem ntawm kev lag luam yuav ncav cuag 30-40%. Cov thev naus laus zis no tau npaj los txhawb kev siv ntau yam thiab kev loj hlob ntawm kev lag luam ruaj khov.
Kev Siv Tshuab Perovskite
Perovskite tau txais kev qhuas ua tus thawj coj ntawm cov thev naus laus zis PV tiam thib peb, khav txog kev ua haujlwm zoo, kev ua haujlwm zoo hauv qhov kaj tsawg, thiab cov txheej txheem yooj yim. Nws cov qauv tandem cog lus tias yuav ua rau muaj kev hloov pauv ntau dua 45%. Cov kev tshawb pom tshiab hauv kev ruaj khov yog ib qho tseem ceeb. Los ntawm xyoo 2027, perovskite xav tias yuav ua tiav kev tsim khoom loj, qhib lub peev xwm thoob plaws cov lag luam xws li IoT, EVs, thiab aerospace, thaum ua kom nrawm hloov mus rau lub zog rov ua dua tshiab.
Cov thev naus laus zis siab heev no sawv cev rau yav tom ntej zoo rau kev lag luam PV, muab cov kev tshiab rau kev txhim kho kom ruaj khov thiab zoo.
