Oosonzululwazi abalishumi baqikelele iindlela ezintsha zobuchule betekhnoloji yeeseli zePV kule minyaka mihlanu izayo, kwinqaku elivulekileyo lokufikelela iseli.
Nangona amandla e-PV afakiweyo kwihlabathi jikelele adlula i-terawatt eyi-1 (i-1,000 GW), igalelo lelanga ekuveliseni umbane kwihlabathi lihlala lincinci, abaphandi bathi, kwi-5% ukuya kwi-6%. Ngokunikwa "imfuno engxamisekileyo" yokuthumela i-PV kwisikali se-terawatt ezininzi kule minyaka ingamashumi amabini izayo ukunciphisa ukukhutshwa kwegesi yegreenhouse, "ubuchule bePV obutsha buthatha ungxamiseko kunye nefuthe elitsha."
Uphando oluqhubekayo olukhokelela "kwinkqubela phambili encinci" ekusebenzeni, ukuthembeka kunye nokusebenza kakuhle "kuya kuba neempembelelo ezinkulu zexesha elizayo kwi-multi-TW isikali," abaphandi bathi, beqaphela ezi zinto zidibanisa ukwenza "isiphakamiso sexabiso esinyanzelisayo" sokuveliswa kwamandla e-PV.
Ngelixa i-crystalline silicon PV yayinesabelo semakethi esingama-95% ngo-2022, “kwikamva le-terawatt-scale” kunye ne “PV kuyo yonke indawo,” bathe ubuchwephesha obuninzi bunokuhambelana, okanye zidityanisiwe.
Itekhnoloji ye-silicon ye-PV eyaziwa ngokuba yi-TOPCon (i-tunnel oxide passivating contact), enesabelo semarike ye-23%, iya "koyisa" ukuveliswa kwe-PERC (i-emitter egqithisiweyo kunye neseli yangasemva) i-PV ngo-2025 kwaye "inokwenzeka ukuba ibe yiteknoloji yokukhetha ukuveliswa kweeseli ezintsha e-US," inqaku liqikelela.
Iiseli ze-Crystalline silicon ze-PV zisondela kwi-single-junction yethiyori ephezulu ye-29.4%, batsho.
Uphando lusafuneka, bayaqaphela, ukuphuhlisa ubushushu obuphezulu, indawo ekhethiweyo yokudlula abafowunelwa kumacala omabini eseli ye-PV ("advanced TOPCon"), ukuphucula ukungafihli kunye nokuhanjiswa kwe-heterojunction technology (HJT) abafowunelwa ("i-HJT ephuculweyo"), kunye nokudibanisa i-HJT yamva nje okanye i-TOPCon itekhnoloji enokuthi ifikelele kwi-interview ye-interface enokufikelela kwi-interactive I-28% inokwenzeka ngokukhawuleza ngo-2025. "
Nangona kunjalo njengoko umda wethiyori usondela, "iindlela ezininzi zokuwohloka, ezibizwa ngokuba yi-Carrier-induced degradation, kunye neziphene eziguquguqukayo ziyatyhilwa," abaphandi batsho.
Ishishini "lisebenzela ukunciphisa okanye ukuphelisa" ukusetyenziswa kwezinto ezinqabileyo ezifana nesilivere yokwenziwa kwemigca yegridi kunye ne-indium esetyenziswa kwi-transparent conductive oxides, ababhali bathi. Iinkampani ezininzi ze-PV kunye neelebhu zophando zibhengeze uyilo lweseli ye-HJT ye-PV ngokunciphisa ukusetyenziswa kwe-indium "okanye i-indium-free" iiseli ze-HJT.
Umthombo ovela pv imagazini
Ukuziphendulela: Ulwazi oluchazwe ngasentla lunikezelwa yimagazini ye-pv ngaphandle kwe-Cooig.com. I-Cooig.com ayenzi lumelo kunye neziqinisekiso malunga nomgangatho kunye nokuthembeka komthengisi kunye neemveliso.
