Bafuputsi ba thehile le ho bonts'a li-photodetectors tse ncha tse tala tse monyang pepenene tse nang le kutloelo-bohloko le tse tsamaellanang le mekhoa ea tlhahiso ea CMOS. Ho kenyelletsa li-photodetectors tsena tse ncha ho li-sensor tsa setšoantšo sa silicone tse nyalisitsoeng ho ka ba molemo bakeng sa lits'ebetso tse ngata. Lisebelisoa tsena li kenyelletsa tlhahlobo e thehiloeng ho sekhahla sa pelo, ho lemoha menoana le lisebelisoa tse lemohang boteng ba lintho tse haufi.
Ebang li sebelisoa ho li-smartphones kapa lik'hamera tsa saense, boholo ba li-sensor tsa litšoantšo kajeno li thehiloe ho theknoloji ea CMOS le li-inorganic photodetectors tse fetolelang mats'oao a leseli hore e be matšoao a motlakase. Leha li-photodetectors tse entsoeng ka thepa ea tlhaho li hohela tlhokomelo hobane li ka thusa ho ntlafatsa kutloisiso, ho bonahetse ho le thata ho etsa li-photodetectors tse sebetsang hantle haholo.
Mofuputsi-'moho le eena Sungjun Park, oa Univesithi ea Ajou Korea Boroa, o itse: "Ho kenyelletsa li-photodetectors tsa tlhaho ka har'a li-sensors tsa litšoantšo tsa CMOS tse entsoeng ka bongata ho hloka lisebelisoa tse monyang khanya tse bonolo ho li etsa ka tekanyo e kholo le tse khonang ho lemoha litšoantšo tse hlakileng ho hlahisa litšoantšo tse bohale. ka litekanyetso tse phahameng tsa foreimi lefifing. Re thehile li-photodiode tse bonaletsang, tse nang le kutloelo-bohloko tse tala tse ka fihlelang litlhoko tsena. ”
Bafuputsi ba hlalosa setšoantšo se secha sa organic photodetector koranteng ea Optica. Ba boetse ba thehile sensara ea ho nahana ea RGB e nyalisitsoeng ka ho phahamisa "photodetector" ea botala bo bonaletsang holim'a silicon photodiode e nang le lifilimi tse khubelu le tse putsoa.
Kyung-Bae Park, moetapele-'moho le moeta-pele oa sehlopha sa lipatlisiso ho tsoa Samsung Advanced Institute of Technology (SAIT) Korea Boroa, o itse: "Ka lebaka la ho hlahisoa ha lebasetere la organic buffer layer, lera le khethang botala le monyang khanya le sebelisitsoeng. lisensara tsena tsa litšoantšo li fokotsa haholo puisano pakeng tsa lipikselse tse fapaneng tsa mebala, ’me moralo ona o mocha o ka etsa hore li-photodiode tse sebetsang hantle haholo e be karolo e ka sehloohong ea li-module tsa ho nka litšoantšo le li-photosensor bakeng sa likopo tse fapaneng.”
Lisebelisoa tse ling tse sebetsang tsa organic photodetectors
Lisebelisoa tse ngata tsa manyolo ha li tšoanelehe bakeng sa tlhahiso ea bongata ka lebaka la kutloisiso ea tsona ho mocheso. E ka 'na ea sitoa ho mamella mocheso o phahameng o sebelisoang bakeng sa phekolo ea morao-rao kapa ea fetoha e sa tsitsang ha e sebelisoa ka mocheso o itekanetseng ka nako e telele. Ho hlola phephetso ena, bo-ramahlale ba tsepamisitse maikutlo ho lokiseng karolo ea "buffer" ea "photodetector" ho ntlafatsa botsitso, ts'ebetso le ho lemoha. Detectability ke tekanyo ea hore na sensor e khona ho bona matšoao a fokolang hakae. "Re hlahisitse bath copper line (BCP) : C60 hybrid buffer layer e le lera la lipalangoang tsa elektronike, e fanang ka lisebelisoa tse ikhethang tsa organic photodetector, ho kenyeletsoa ts'ebetso e phahameng le hona joale e lefifi, e fokotsang lerata," ho bolela Sungjun Park. Photodetector e ka behoa holim'a silicon photodiode e nang le li-filters tse khubelu le tse putsoa ho etsa sensor ea setšoantšo sa lebasetere.
Bafuputsi ba bonts'a hore photodetector e ncha e bonts'a litekanyetso tsa ho lemoha tse bapisoang le tsa silicon photodiodes tse tloaelehileng.
