Izazinzulu ziyaqhubeka nokutyhalaiiphaneli zelangaukuba isebenze ngakumbi, kwaye kukho irekhodi elitsha lokunika ingxelo: Iseli entsha yelanga ifezekisa ukusebenza kakuhle kweepesenti ze-39.5 phantsi kweemeko eziqhelekileyo zokukhanya kwelanga eli-1.
I-1-sun mark yindlela nje esemgangathweni yokulinganisa isixa esimiselweyo sokukhanya kwelanga, ngoku phantse i-40% yemitha yemitha inokuguqulwa ibe ngumbane. Ingxelo yangaphambili yolu hloboiphaneli yelangaimathiriyeli ibiyi-39.2% esebenzayo.
Kukho iintlobo ezininzi zeeseli zelanga ezijikelezileyo kunokuba unokucinga.Uhlobo olusetyenziswe apha ziiseli zelanga ze-triple-junction III-V tandem, eziqhele ukubekwa kwiisathelayithi kunye neziphekepheke, nangona zikwanamandla amakhulu kumhlaba oqinileyo.
"Iiseli ezitsha zisebenza kakuhle kwaye zilula ukuyila, kwaye zinokuba luncedo kwiintlobo ezahlukeneyo zezicelo, ezifana nezicelo ezinyanzeliswayo okanye ukukhutshwa kwendawo ephantsi," watsho i-physicist Myles Steiner weNational Renewable Energy Laboratory..”NREL) eColorado.
Ngokumalunga nokusebenza kakuhle kweeseli zelanga, inxalenye ye "triple junction" ye-equation ibalulekile.Iqhina ngalinye ligxininiswe kwindawo ethile yoluhlu lwe-solar spectral, oku kuthetha ukuba ukukhanya okuncinci kulahlekile kwaye kungasetyenziswanga.
Ukusebenza kuphuculwe ngakumbi ngokusebenzisa oko kubizwa ngokuba yi-teknoloji ebizwa ngokuba yi "quantum well".Ifiziksi emva kwabo inzima kakhulu, kodwa ingcamango jikelele kukuba izinto zikhethwe ngononophelo kwaye ziphuculwe, kwaye zincinci kangangoko kunokwenzeka.Oku kuchaphazela i-gap band, Ubuncinci bomthamo wamandla ofunekayo ukonwabisa ii-electron kwaye uvumele umsinga ukuba uqukuqele.
Kule meko, udibaniso oluthathu lubandakanya i-gallium indium phosphide (GaInP), i-gallium arsenide (i-GaAs) kunye ne-quantum eyongezelelweyo yokusebenza kakuhle, kunye ne-gallium indium arsenide (GaInAs).
"Into ephambili kukuba ngelixa i-GaAs iyinto ebalaseleyo kwaye isetyenziswa ngokuqhelekileyo kwiiseli ze-III-V ezininzi, ayinayo i-bandgap echanekileyo yeeseli ezidibeneyo ezintathu, oku kuthetha ukuba i-photocurrent phakathi kweeseli ezintathu Ibhalansi ayilunganga, ” yatsho ingcali yefiziksi yakwaNREL uRyan France.
"Apha, sitshintshe umsantsa webhendi ngokusebenzisa amaqula e-quantum, ngelixa sigcina umgangatho obalaseleyo wezinto eziphathekayo, ovumela esi sixhobo kunye nezinye iinkqubo ezinokuthi zibekho."
Olunye uphuculo olongeziweyo kule seli yamva nje lubandakanya ukwanda kokukhanya okufunxayo ngaphandle kokulahleka kombane ohambelanayo.Iindlela ezininzi zobugcisa zenziwe ukunciphisa izithintelo.
Le yeyona ndlela iphezulu yelanga eli-1 kuyo nayiphi naiphaneli yelangaiseli kwirekhodi, nangona siye sabona impumelelo ephezulu ukusuka kwimitha yelanga ebukhali ngakumbi.Ngelixa kuya kuthatha ixesha lokuba itekhnoloji ihambe ukusuka kwilebhu ukuya kweyona mveliso, uphuculo olunokubakho lunika umdla.
Iiseli ziphinde zirekhode i-34.2 yeepesenti esebenzayo yendawo, eyona nto kufuneka iphumelele xa isetyenziswe kwi-orbit.
"Njengoko ezi zezona zisebenza kakuhle kakhulu iiseli zelanga ze-1 ngexesha lokubhala, ezi seli nazo zibeka umgangatho omtsha wokufezekiswa kokufezekiswa kwazo zonke iteknoloji ye-photovoltaic," abaphandi babhala kwiphepha labo elipapashwe.
