Ifoto yumukara Silicon Photodetector Yanditse: Urwego rwo hanze rugera kuri 132%

Umukara SiliconPhotodetetectorInyandiko: Urwego rwo hanze rugera kuri 132%

Nk'uko byatangajwe n'ibitangazamakuru, abashakashatsi kuri kaminuza ya adoteri bateguye igikoresho cya optoelectronic hamwe na quanim yo hanze ya 132%. Ibi ntibishoboka ko byagezweho ukoresheje Silicon yumukara wa silicon, bishobora kuba intambwe ikomeye kubitueli nizindiamafoto. Niba ibikoresho bya pacpothetiltaic bifite uburyo bwo hanze bwa 100 ku ijana, bivuze ko buri fononi ikubita itanga electron, ikakusanywa nkamashanyarazi binyuze mumuzunguruko.

Kandi iki gikoresho gishya ntabwo kugera ku bikorwa 100 ku ijana, ariko birenze 100 ku ijana. 132% bisobanura impuzandengo ya 1,32 electron kuri photon. Ikoresha silicon yumukara nkibikoresho bikora kandi ifite cone na colnuture yubutaka bushobora gukuramo urumuri rwa ultraviolet.

Biragaragara ko udashobora gukora amagorofa 0.32 yo mu kirere, nyuma ya byose, fiziki avuga ko imbaraga zidashobora kurerwa mu kirere cyoroshye, none aya mashanyarazi y'inyongera ava he?

Byose bimanuka kumahame rusange akora ibikoresho bya PhotoVoltaic. Iyo foto ya photon yimyandiro ikubita ibintu bikora, mubisanzwe silicon, ikomanga electron muri imwe muri atome. Ariko mubihe bimwe, foto yingufu nyinshi irashobora gukuramo electron ebyiri utaravamo amategeko ayo ari yo yose ya fiziki.

Ntagushidikanya ko gukoresha iki kintu bishobora gufasha cyane mugutezimbere igishushanyo mbonera cyizuba. Mubikoresho byinshi bya optoelectronic, imikorere yazimiye muburyo butandukanye, harimo mugihe ifoto igaragara kubikoresho cyangwa electrons recombine hamwe na "umwobo" mbere yo gukusanywa numuzunguruko.

Ariko itsinda rya Aalto rivuga ko bakuyeho aha inzitizi. Silicon yumukara ikurura amafoto kurusha ibindi bikoresho, hamwe nibikorwa bya kashe kandi byinkingi na colImnar bigabanya kwizirika kwa electron hejuru yibikoresho.

Muri rusange, izo nyungu zashoboje uburyo bwo hanze bwigikoresho kugirango ugere kuri 130%. Ibisubizo by'ikipe ndetse byigenga byagenzuwe n'ubutegetsi bw'igihugu cy'Ubudage, PTB (Ikigo cy'Ubudage cya Firmsics ya fiziki).

Nk'uko abashakashatsi bavuga ko iyi nyandiko ikora neza ishobora kunoza imikorere muri ahanini Photodetector iyo ari yo yose, harimo selile y'izuba hamwe n'abandi basekuruza bashya, kandi gahunda nshya imaze gukoreshwa mubucuruzi.
