Iiphaneli zelanga ze-HJT: Ukukhokela ikamva lamandla elanga
Khawuthelekelele ihlabathi apho iiphaneli zelanga zinokubamba phantse yonke imisebe yelanga, ziyiguqule ibe ngamandla acocekileyo, ahlaziyekayo ngokusebenza kakuhle okungenakuthelekiswa nanto. Wamkelekile kwixesha leTekhnoloji yeHeterojunction (HJT), inkqubela phambili entsha ebeka imigangatho emitsha kwishishini le-photovoltaic (PV). Ngesakhiwo sayo esahlukileyo kunye nokusebenza kwayo okugqwesileyo, i-HJT ayisiyonto intsha nje yetekhnoloji kodwa sisibane sethemba lekamva elizinzileyo.
Umlingo Ongasemva KweTekhnoloji ye-HJT
I-HJT, isifinyezo seTheknoloji yeHeterojunction, simangalisa kakhulu kumhlaba wamandla elanga. Ngokungafaniyo neephaneli zelanga zemveli ezixhomekeke kuhlobo olunye lwesilicon, iiphaneli ze-HJT zisebenzisa indibaniselwano enobuchule yeeleya zesilicon, nganye idlala indima ebalulekileyo ekusebenziseni amandla elanga.
1. Umaleko Ophezulu: I-Amorphous Silicon – I-Light Catcher
Khawuthelekelele ifilimu ethambileyo nebhityileyo yesilicon ebamba ukukhanya kwelanga okokuqala, iqala utshintsho olumangalisayo lokukhanya lube ngumbane.
2. Umaleko oPhakathi: I-Crystalline Silicon – I-Powerhouse
Ngaphantsi komaleko ongaphezulu kukho i-crystalline silicon, i-absorber yokukhanya eqinileyo nesebenzayo. Olu maleko luphakathi kwephaneli ye-HJT, apho uninzi lokukhanya luguqulwa lube ngamandla ombane.
3. Umaleko Osezantsi: I-Amorphous Silicon – I-Photon Hunter
Njengoko ukukhanya kudlula kwiileya eziphezulu, naziphi na iiphoton eziseleyo zibanjwa lulwaleko olusezantsi lwesilicon engenasimo. Oku kuqinisekisa ukuba akukho msebe wokukhanya ochithakalayo, nto leyo ekhulisa imveliso yamandla.
Indlela iiphaneli zelanga ze-HJT ezisebenza ngayo ngomlingo wazo
Uyilo oluneeleya ezininzi lweephaneli ze-HJT lufana ne-symphony yokukhanya kunye ne-silicon. Xa ilanga libetha iphaneli, umaleko ophezulu we-silicon engenasimo ufunxa ukukhanya okuthile, uvelise itshaja yokuqala yombane. Umaleko we-silicon ophakathi wekristale uthatha indawo, uguqula ubukhulu bokukhanya bube ngamandla ombane. Ekugqibeleni, umaleko we-silicon ongenasimo osezantsi ubamba ii-photon eziseleyo, utyhalela ukusebenza kakuhle kwephaneli kwiindawo ezintsha.
Ukusebenza kakuhle: Ilitye Eliqaqambileyo leePaneli ze-HJT
Iiphaneli ze-HJT zezona zibalaseleyo kwihlabathi lelanga, ziqhayisa ngobuchule bokuguqula obunomona kwiiteknoloji zemveli. Ngelixa iiphaneli ze-PERC zilawula ukusebenza kakuhle malunga ne-20%, kwaye iiphaneli ze-TOPCon zinyuka ziye kuthi ga kwi-23%, iiphaneli ze-HJT zilawula kakuhle ngobuchule obucalanye obuyi-26-27%. Nangona kunjalo, eyona nto iphambili yiphaneli ye-HJT enezimo ezimbini, eqaqamba ngobuchule obungaphezulu kwe-30%. Oku kwenza i-HJT ibe yeyona teknoloji isebenzayo ngoku ekhanyisa ishishini le-PV.
Iimpawu Ezikhethekileyo Zeephaneli Zelanga ze-HJT
1. Indlela elula yokuvelisa
Ukwenza iiphaneli ze-HJT yinto elula, ebandakanya amanyathelo amane angaphantsi kokuveliswa kweephaneli zelanga zemveli. Oku akukhawulezisi nje kuphela inkqubo yokwenziwa kodwa kunciphisa neendleko.
2. Ukusebenza kakuhle kokuguqula okungalinganiyo
Ngenxa yesakhiwo sayo se-silicon esinee-multilayer, iiphaneli ze-HJT zibonelela ngokufunxwa kokukhanya okuphezulu kunye nokuguqulwa kwamandla, zidlula kakhulu ubuchwepheshe be-PERC kunye ne-TOPCon.
3. Ummangaliso Omacala Ambini
Iiphaneli ze-HJT zibalasele kwiisetingi ezimbini, apho omabini amacala ephaneli asebenza khona. Olu kukhanya lumacala mabini luvumela ukukhutshwa kwamandla amakhulu ukusuka kwindawo enye, okwenza i-intshi nganye ibalwe.
4. Iqhawe lobushushu
Iiphaneli ze-HJT ziyachuma kwiindawo ezinobushushu obuphezulu, zigcina ukusebenza kwazo okuphezulu nokuba i-mercury inyuka. Oku kuzenza zilungele iindawo ezinelanga nezishushu apho ezinye iiphaneli zinokuwohloka khona.
Uhambo lweMarike lwe-HJT kunye neXesha elizayo
Nangona isebenza kakuhle, iteknoloji ye-HJT okwangoku ithatha indawo encinci kwimarike. I-TOPCon inesabelo esikhulu semarike se-70%, ngelixa i-HJT ine-5% kuphela. Ixabiso eliphezulu leephaneli ze-HJT, ukusuka kwi-$0.13 ukuya kwi-$0.20 nge-watt, xa kuthelekiswa ne-$0.10 nge-watt engabizi kakhulu kwiimodyuli ze-P-type kunye ne-N-type, yinto ephambili. Nangona kunjalo, ikamva liqaqambile kwi-HJT njengoko ukuqhubela phambili kuqhubeka nokunciphisa iindleko, okwenza obu buchwepheshe bufikeleleke lula.
Ikamva Likhanya Ngokuqaqambileyo nge-HJT
Iiphaneli zelanga ze-HJT azikho nje inyathelo eliya phambili; zinyathelo elikhulu kwishishini le-photovoltaic. Ngemveliso yazo elula, ukusebenza kakuhle okuphezulu, kunye nokusebenza okuphezulu phantsi kweemeko ezahlukeneyo, iiphaneli ze-HJT zikulungele ukuba ngumgangatho wegolide kumandla elanga. Njengoko ihlabathi liqhubeka nokwamkela amandla ahlaziyekayo, itekhnoloji ye-HJT ikulungele ukukhokela umbane ukuya kwikamva eliqaqambileyo nelizinzileyo.
Ngoko ke, kwixesha elizayo xa uziva ilanga lifudumele, khumbula i-symphony engathethiyo yeephaneli ze-HJT, iguqula ukukhanya kube ngamandla anika amandla ubomi bethu. Kuyo yonke imisebe, kukho isithembiso sekamva eliluhlaza ngakumbi, kwaye i-HJT ilapha ukuze yenze eso sithembiso sibe yinyani.
