Ukuqaliswa kweBreif kweCu nanopowders kwisicelo seseli yeSolar:

Iseli yelanga sisixhobo esiguqula amandla elanga abe ngamandla ombane.Umgaqo oyintloko kukusebenzisa umphumo we-photoelectric we-semiconductors.Xa ukukhanya kwelanga kukhanya kwiseli yelanga, imathiriyeli yeseli ifunxa ukukhanya kwesiganeko sobude obuthile, kwaye iifotoni ziyachulumancisa ukuvelisa iperi ye-electron emngxunyeni, emva koko iguqule amandla okukhanya abe ngamandla ombane.Kodwa xa ukukhanya kwelanga kukhanya kwiseli yelanga, ukukhanya kwelanga kuyabonakala, kutsalwe kwaye kudluliselwe.Indlela yokunciphisa ukubonakaliswa kweseli yelanga yokukhanya kwelanga, ukuze kufumaneke iperi ye-electron-hole eyongezelelekileyo eyenziwe ngeefoto kunye nokwandisa ukusebenza kakuhle koguqulo lombane wefoto, ibe ngumba obalulekileyo ekufuneka usonjululwe.
Ngokusebenzisa iinzame eziqhubekayo kunye nophando lwabaphandi bezenzululwazi, indlela yokusebenzisa i-nano-metal particles ukuvelisa i-surface plasmon resonance kunye nokukhanya kwesiganeko phezu kweeseli zelanga ziye zacetywa.I-surface plasmon resonance inokufunxa amandla eefotoni.Xa i-frequency yesiganeko sokukhanya ilingana okanye isondele kwi-oscillation frequency, ukukhanya kwesiganeko kuya kuvalelwa kufuphi ne-plasmon yomhlaba, ngaloo ndlela kwandisa ukufunxwa kokukhanya, ukwenzela ukuba amandla elanga afunyenwe yiseli yelanga inani lilonke liye landa. yona iphucula ukusebenza kwayo okubonakalayo, okubizwa ngokuba yi-surface plasmon yokuphucula iseli yelanga.Ubhedu lwe-Metallic lune-conductivity efanelekileyo ye-thermal, kunye ne-nanofluid egcwele i-nano powder yobhedu (i-Cu nanoparticle) ayinayo kuphela i-conductivity ye-thermal efanelekileyo, kodwa ibonisa nokusebenza okuqinileyo kwi-band yokukhanya ebonakalayo, efanelekileyo kakhulu njengombane ojikelezayo wokusebenza ngokuthe ngqo. abaqokeleli belanga.Ukulungiswa kwe-nanofluids kusisiseko sazo zonke iingxaki ze-nanofluid, ezibandakanya ngokukodwa ukulungiswa kokulawulwa kwee-nanoparticles kunye nokusabalalisa okuzinzile kwe-nanoparticles kwi-fluid yesiseko.
Ezi nkcukacha zingentla zenzelwe ireferensi kuphela.Kwidatha yokwenyani yesicelo, kufuneka ivavanywe ngokwefomula yakho.
