Maererano nevefizikiki sangano network munguva pfupi yapfuura yakashuma kuti vatsvakurudzi veFinnish vakagadzira nhema silicon photodetector ine yekunze quantum kunyatsoshanda kwe130%, inova kekutanga kuti kushanda kwe photovoltaic device kunodarika muganhu wezvinyorwa zve100%, izvo zvinotarisirwa zvikuru. kunatsiridza mashandiro emagetsi ekuona mapikicha, uye michina iyi inoshandiswa zvakanyanya mumotokari, nharembozha, smart wachi nemidziyo yekurapa.
Photodetector inzwa inokwanisa kuyera chiedza kana rimwe simba remagetsi, kushandura mafotoni kuita magetsi emagetsi, uye mafotoni akabatwa anoumba electron-hole pairs.Iyo photodetector inosanganisira photodiode uye phototransistor, nezvimwewo. Quantum kunyatsoshanda kunoshandiswa kutsanangura chikamu chemazana emafotoni anogamuchirwa nemudziyo wakadai se photodetector mu electron-hole pair, kureva kuti, quantum performance yakaenzana nenhamba ye photogenerated electrons yakakamurwa ne. nhamba yemafotoni echiitiko.
Kana chiitiko chephoton chichigadzira erekitironi kudunhu rekunze, iyo yekunze quantum kunyatsoshanda kwechigadzirwa i100% (yaimbofungidzirwa kuti ndiyo muganhu wedzidziso).Muchidzidzo chazvino, iyo nhema silicon photodetector yaive nehunyanzvi hwekusvika 130 muzana, zvinoreva kuti chiitiko chimwe chete chephoton chinoburitsa maerekitironi 1.3.
Sekureva kwevaongorori veAalto University, chombo chakavanzika kuseri kwekubudirira kukuru uku ndiko kubhadharisa-mutakuri wekuwedzera maitiro anoitika mukati meyakasarudzika nanostructure yedema silicon photodetector, iyo inokonzereswa neakakwira-simba mafoto.Kare, masayendisiti akange asina kukwanisa kuona chiitiko mumidziyo chaiyo nekuti kuvepo kwemagetsi uye kurasikirwa kwemaziso kwakaderedza huwandu hwemaerekitironi akaunganidzwa."Midziyo yedu yakaitwa nanostructured haina recombination uye haina kurasikirwa kwekufungidzira, saka tinokwanisa kuunganidza zvese zvakawandisa zvinotakura zvinotakura," akatsanangura mutungamiri wekudzidza Purofesa Hera Severn.
Kushanda uku kwakasimbiswa neInstitute of Physical Technology yeGerman National Metrology Society (PTB), iyo yakanyatso kurongeka uye yakavimbika sevhisi yekuyera muEurope.
Vatsvagiri vanocherekedza kuti kuita rekodhi uku kunoreva kuti masayendisiti anogona kuvandudza zvakanyanya mashandiro emagetsi ekuona mafoto.
"Madhigirii edu akaunza kufarira kwakawanda, kunyanya munzvimbo dzebiotechnology uye indasitiri yekuongorora maitiro," akadaro Dr. Mikko Juntuna, CEO weElfysInc, kambani yeAalto University.Zvinonzi vatanga kugadzira michina yakadaro kuti ishandiswe pakutengeserana.
