Mphamvu ya dzuwa ikukopa chidwi ngati gwero la mphamvu zamtsogolo m'badwo wotsatira wa zinthu. HPBC ndi imodzi mwa njira zomwe zikuthandizira pakukula kwa ukadaulo wa maselo a dzuwa. Maselo a HPBC ali ndi ubwino wa kapangidwe ka kukhudzana kumbuyo mogwirizana ndi ukadaulo wotulutsa mpweya wosasunthika komanso ukadaulo wolumikizirana wosasunthika kumbuyo (PERC). Kapangidwe kameneka nthawi zambiri kamapanga kukhudzana kosasunthika kumbuyo kwa selo kuti achepetse chitetezo chakutsogolo ndikuwonjezera kuyamwa kwa kuwala.
Selo ya HPBC, dzina lake lonse ndi Hybrid Passivated Back Contact (HPBC), ndipo ndi mbadwo watsopano wa ukadaulo wa maselo a dzuwa omwe amagwira ntchito bwino kwambiri.
Makhalidwe a kapangidwe kake: Maselo a HPBC okhala ndi chotulutsira mpweya chopanda mphamvu ndi cholumikizira cha kumbuyo chopanda mphamvu chophatikizidwa (PERC) pogwiritsa ntchito kapangidwe kake ka kukhudzana kumbuyo, kapangidwe kake nthawi zambiri kamapangidwa kumbuyo kwa cholumikizira cha batri chopanda mphamvu kuti chichepetse mthunzi wakutsogolo, ndikuwonjezera kuyamwa kwa kuwala. Mphamvu ya kusuntha: Gawo la kusuntha la maselo a HPBC limathandiza kuchepetsa kusakanikirana kwa pamwamba ndikuwonjezera voliyumu yotseguka (Voc) ya selo.
Zinthu Zaukadaulo: Ukadaulo wa maselo a HPBC umaphatikiza ukadaulo wa TOPCon ndi IBC kuti usunthire mizere yonse ya gridi yachitsulo ya maselo, yomwe imayang'anira kusonkhanitsa ndi kunyamula zonyamulira, kumbuyo kwa module, zomwe zimapangitsa kuti mbali yakutsogolo ya selo ikhale yopanda kutsekeka kwa mizere ya gridi, motero kumawonjezera kugwiritsa ntchito kuwala komanso mphamvu yosinthira kuwala kwa dzuwa.
Ubwino Waukadaulo: Mabatire a HPBC amadziwika ndi kuyamwa kwamphamvu kwa kuwala, mphamvu yosinthira kwambiri, mphamvu yotumizira yokhazikika, zinthu zokongola, komanso ukadaulo wokhwima komanso wodalirika.
Chitsanzo Chogwiritsira Ntchito: Maselo a HPBC ndi oyenera mwachilengedwe pazochitika za PV zogawidwa, makamaka BIPV (Building Integrated Photovoltaic), zomwe zimatha kuphatikiza bwino kukongola kwa ma module a BC ndi zaluso zomanga.
Batire ya TBC (TOPCon Back Contact) ya TBC, dzina lake lonse ndi batire yophatikizana ya ukadaulo wa TOPCon ndi IBC, yomwe imadziwikanso kuti batire ya POLO-IBC. Makhalidwe ake: Batire ya TBC imagwiritsa ntchito tunnel oxide layer passivation contact (TOPCon) ndikuyiyika pa kapangidwe kake ka contact yakumbuyo. Kapangidwe kake kamagwiritsa ntchito passivation yapamwamba komanso mawonekedwe abwino a ukadaulo wa TOPCon.
Kuthekera kogwira ntchito bwino: Maselo a TBC ali ndi kuthekera kogwira ntchito bwino kwambiri chifukwa cha mphamvu zawo zabwino zosinthira mphamvu komanso kapangidwe kake kolumikizana ndi kumbuyo. Njira yopangira mafakitale: Pakadali pano, njira yaukadaulo wa batri ya TBC ili mu gawo lofufuza la labotale, ndipo pali mavuto ambiri omwe akufunika kuthetsedwa kuti apititse patsogolo njira yopangira mafakitale. M'kanthawi kochepa, njira ya batri ya TBC ili ndi chiyembekezo chachikulu cha chitukuko, chifukwa njira yopangira ya TOPCon ndi yokhwima kuposa njira yopangira ya HJT, mtengo wake ndi wotsika, ndipo mzere wopanga wa TBC umagwirizana pang'ono ndi mzere wopanga wa TOPCon.
Kugwiritsa Ntchito: Maselo a TBC angagwiritsidwe ntchito osati kokha pa substrate ya silicon ya crystalline ya mtundu wa N, komanso pa substrate ya mtundu wa P, yomwe ili ndi kuthekera kwakukulu kowongolera magwiridwe antchito a photoelectric ndikuchepetsa ndalama.
Maselo a dzuwa a HBC (Heterojunction Back Contact) Maselo a HBC, kutanthauza maselo a silicon a crystalline a heterojunction back, ndi kuphatikiza kwa ukadaulo wa heterojunction (HJT) back contact ndi ukadaulo wa cross index (IBC) high-efficiency solar cell.
Kapangidwe kake: Maselo a HBC amagwiritsa ntchito ukadaulo wa heterojunction pamodzi ndi kapangidwe ka back-contact. Kuti akwaniritse bwino kusonkhanitsa chonyamulira, kapangidwe kameneka nthawi zambiri kamapanga heterojunction kumbuyo kwa selo.
Mphamvu Yogwira Ntchito Kwambiri: Maselo a HBC amaonedwa kuti ndi abwino kwambiri pakugwiritsa ntchito maselo a dzuwa chifukwa cha makhalidwe awo abwino kwambiri a heterojunction komanso kapangidwe kake kolumikizana ndi kumbuyo. Maselo a hpbc, tbc, ndi hbc onse akuyimira kupita patsogolo kwa ukadaulo wa maselo a photovoltaic, ndi njira zosiyanasiyana zaukadaulo kuti awonjezere mphamvu ya kusintha kwa photovoltaic kwa maselo. Ponena za mphamvu ya kusintha, maselo a TBC ndi HBC amaposa ukadaulo wakale wa IBC. Maselo a HBC amaphatikiza mphamvu ya pamwamba ya maselo a HJT ndi ubwino wa chitetezo chopanda zitsulo kutsogolo kwa maselo a IBC, ndipo ali ndi ubwino wowirikiza wa mafunde afupiafupi komanso ma voltages ambiri otseguka, ndipo amayimira mphamvu yapamwamba kwambiri ya kusintha kwa photovoltaic kwa maselo a solar a crystalline silicon.
