Irekhodi le-Silicon Fopidepectortector Resoctor: Ukusebenza kwangaphandle kwenqanaba ukuya kuthi ga kwi-132%

I-Silicon emnyamaifotoRekhoda: Ukusebenza kwangaphandle kwexabiso ukuya kwi-132%

Ngokweengxelo zeMidiya, abaphandi kwiYunivesithi yaseAalto baphuhlise isixhobo se-Optoectronic esinendlela yokuphumelela kwi-132%. Oku kungalindelekanga ngokusebenzisa i-Nanostard Slicon, enokuba yinto ephambili yeeseli zelanga kunye nezinyeIifoto. Ukuba isixhobo se-hypothetical i-photovoltaic ineenkqubo ze-100 pesenti, oko kuthetha ukuba yonke i-photon efihla ivelisa i-elektroni, eqokelelwa njengombane kwisekethe.

Kwaye esi sixhobo sitsha singafezekisi kuphela ngepesenti ezili-100 zokusebenza, kodwa ngaphezulu kwe-100 pesenti. I-132% ithetha umndilili we-1.32 yee-elektroniki kwi-Photon. Isebenzisa i-silicon emnyama njengento esebenzayo kwaye ine-cone kunye nokukhanya kwe-Colminar enokufumana ukukhanya kwe-ultraviolet.

Ngokucacileyo awukwazi ukwenza i-0.32 i-elektroni eyongezelelweyo ngaphandle komoya omdaka, emva kwayo yonke loo nto, ifiziksi ithi amandla akanakuzenziwa umoya onqabileyo, ke avela phi ezi zombane?

Yonke le ihla kumgaqo wokusebenza ngokubanzi wezixhobo zefotovoltaic. Xa i-photon yesiganeko esikhanyayo inamathela kwinto esebenzayo, idla ngokuba yi-silicon, inkqonkqoza i-elektroni kwenye yeeatom. Kodwa kwezinye iimeko, i-photon enamandla aphezulu inokunkqonkqoza ii-elektroni ezimbini ngaphandle kokwaphula nayiphi na imithetho yefiziksi.

Alithandabuzeki elokuba le nto ibambelela le phenonon inokuba luncedo kakhulu ekuphuculeni uyilo lweeseli zelanga. Kwiimpahla ezininzi ze-optoe oselula, ukusebenza kakuhle kulahlekile ngeendlela ezininzi, kubandakanya xa iifoto zibonakaliswa kwifowuni okanye i-elektroni ziphinda ziphinde zibuyele kwi-Atom ngaphambi kokuba kuqokelelwe kwisekethe.

Kodwa iqela lika-Aaalto lithi bashenxisile kakhulu le miqobo. I-Silicon emnyama ifumana iifoto ezingakumbi kunezinye izinto, kwaye unxweme oluziintloko kunye nolwakhiwo lwe-Colminar kunye nokunciphisa ukubuyiswa kwe-elektroni kumphezulu wezinto ezibonakalayo.

Ngokubanzi, ezi nkqubela ziye zavumisa ukusebenza kakuhle kwesixhobo sokufikelela kwi-130%. Iziphumo zeqela ziye zangqinwa ngokuzimeleyo kwiZiko leMetrolo yaseJamani, i-PTB (i-PTB (i-PTB (i-PTB (yaseJamani ye-Feeral.

Ngokutsho kwabaphandi, le rekhodi inokuphucula ukusebenza ngokusisiseko nawuphi na umzobo, kubandakanya iiseli zelanga kunye nezinye izilonda ezilula, kwaye umzili omtsha sele esetyenziswa ngokuthengisa.
