Ubuchwepheshe bephaneli yelanga obusebenza kahle kakhulu

Isidingo samandla avuselelekayo besilokhu sikhula ngenxa yokukhathazeka okukhulayo mayelana nezindaba zemvelo kanye nesidingo sezinketho zamandla esimeme. Ubuchwepheshe bephaneli yelanga sebuphenduke inketho ethandwayo yokusebenzisa amandla elanga amaningi ukuze kukhiqizwe ugesi. Njengoba umhlaba uqhubeka nokutshala amandla elanga, ukufuna ubuchwepheshe obusebenza kahle kakhulu bephaneli yelanga kuya ngokuya kubaluleke kakhulu. Kulesi sihloko, sizohlola izinhlobo ezahlukene zobuchwepheshe bephaneli yelanga kanye nezinketho ezisebenza kahle kakhulu ezitholakalayo namuhla.

Ubuchwepheshe bephaneli yelanga buhlanganisa izinto ezihlukahlukene kanye nemiklamo, kodwa izinhlobo zephaneli yelanga ezivame kakhulu zihlanganisa amaphaneli elanga e-monocrystalline, i-polycrystalline, nefilimu encane. Uhlobo ngalunye lunezinzuzo zalo kanye nokubi lwalo, futhi ukusebenza kahle kwamaphaneli kungase kuhluke ngokusekelwe ezicini ezifana nezindleko, izidingo zokufakwa, nokusebenza ngaphansi kwezimo ezihlukene zemvelo.

Amaphaneli elanga e-Monocrystallinezenziwe ngesakhiwo se-crystal esisodwa esiqhubekayo, esibanika ukubukeka okufanayo nokusebenza kahle okuphezulu. Lawa maphaneli aziwa ngokubukeka kwawo okumnyama okunesitayela namandla aphezulu. Ngakolunye uhlangothi, amaphaneli elanga e-Polycrystalline enziwe ngamakristalu e-silicon amaningi, awenza afane kancane ngokubukeka futhi angasebenzi kahle kakhulu kunamaphaneli e-monocrystalline. Amaphaneli elanga enziwe ngefilimu emincane enziwe ngokufaka izingqimba ezincane zezinto ze-photovoltaic ku-substrate, futhi nakuba engasebenzi kahle kunamaphaneli e-crystalline, aguquguqukayo futhi alula, okwenza afanelekele izinhlelo zokusebenza ezithile.

Sekuyisikhathi eside ama-solar panels e-Monocrystalline ebhekwa njengendlela ephumelela kakhulu ngokusebenza kahle. Lawa maphaneli anezilinganiso eziphakeme zokusebenza kahle futhi ayakwazi ukuguqula ukukhanya kwelanga kube ugesi uma kuqhathaniswa namaphaneli e-polycrystalline kanye nefilimu encane. Lokhu kusho ukuthi indawo encane iphaneli ye-monocrystalline iyadingeka ukuze kukhiqizwe inani elifanayo likagesi njengendawo enkulu ye-polycrystalline noma iphaneli yefilimu encane. Ngenxa yalokhu, amaphaneli e-silicon e-monocrystalline avame ukuthandwa ukufakwa kwezindawo zokuhlala nezokuhweba ezinendawo elinganiselwe.

Kodwa-ke, imboni yelanga ihlale ishintsha, futhi kuvela ubuchwepheshe obusha obubekela inselele ukubusa okungokwesiko kwamaphaneli e-monocrystalline. Obunye ubuchwepheshe obunjalo ukuthuthukiswa kwe-PERC (emitter passivated kanye neseli yangemuva) amaseli elanga, okuhloswe ngayo ukwandisa ukusebenza kahle kwamaphaneli elanga e-monocrystalline kanye ne-polycrystalline. Ngokungeza ungqimba lwe-passivation endaweni engemuva yeseli yelanga, ubuchwepheshe be-PERC bunciphisa ukuhlangana kabusha kwama-electron futhi kwandisa ukusebenza kahle kweseli. Le ntuthuko ivumele amaphaneli e-monocrystalline kanye ne-polycrystalline ukuthi asebenze kahle kakhulu, okuwenza aqhudelane kakhulu namaphaneli amafilimu amancane.

Enye intuthuko ethembisayo kubuchwepheshe bephaneli yelanga ukusetshenziswa kwamaphaneli elanga ahlukene kabili, athwebula ukukhanya kwelanga kuzo zombili izindawo ezingaphambili nezingemuva zephaneli. Amaphaneli anezinhlangothi ezimbili asebenzisa ukukhanya kwelanga okuvela phansi noma ezindaweni eziseduze ukuze akhiqize ugesi owengeziwe uma kuqhathaniswa namaphaneli avamile anohlangothi olulodwa. Ubuchwepheshe bunamandla okuqhubeka nokuthuthukisa ukusebenza kahle kwamaphaneli elanga, ikakhulukazi ezindaweni ezine-albedo ephezulu noma izindawo ezikhanyayo.

Ngaphezu kwalezi ntuthuko, abacwaningi bahlola izinto ezintsha kanye nemiklamo yamaphaneli elanga, njengamaseli elanga e-perovskite namaseli elanga ahlanganisa ama-multijunction, anamandla okudlula ukusebenza kahle kwamaphaneli elanga asekelwe ku-silicon. Amaseli elanga e-Perovskite, ikakhulukazi, abonisa isithembiso esihle kuzilungiselelo zaselabhorethri, ezinye ze-prototypes zifeza ukusebenza kahle okungaphezu kwama-25%. Nakuba ukuthengiswa kwalezi zobuchwepheshe kusesesigabeni sokucwaninga nokuthuthukiswa, banamandla okuguqula imboni yelanga futhi benze amandla elanga ancintisane kakhulu kunemithombo yamandla evamile.

Kafushane, ukusesha ubuchwepheshe bephaneli yelanga obusebenza kahle kakhulu kuyaqhubeka, ngokuthuthuka kobuchwepheshe be-PERC, amaphaneli akabili, nezinto ezisafufusa ezinikeza amathuba amasha okuthuthukisa ukusebenza kahle kwamaphaneli elanga. Nakuba amaphaneli e-silicon e-monocrystalline sekuyisikhathi eside ebhekwa njengenketho ephumelela kakhulu, ukusungula izinto ezintsha ngokushesha embonini yelanga kuyinselele ezinkambisweni zendabuko futhi kuvula umnyango wamathuba amasha. Njengoba umhlaba uqhubeka nokuguqukela kumandla avuselelekayo, intuthuko yobuchwepheshe bephaneli yelanga izodlala indima ebalulekile ekuqhubekiseni ukwamukelwa kwamandla elanga kanye nokunciphisa ukuthembela kwethu emafutheni ezinto ezimbiwa phansi.

Uma unentshisekelo kumaphaneli elanga e-monocrystalline, wamukelekile ukuthintana nenkampani yelanga yaseChina iRadiance Radiance ukuzethola isaphulelo.
