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 ho ba matšoao a motlakase.

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. ho li-sensor tsena tsa setšoantšo ho fokotsa haholo crosstalk lipakeng tsa lipikselse tsa mebala e fapaneng, 'me moralo ona o mocha o ka etsa hore li-photodiode tse sebetsang hantle haholo e be karolo e kholo ea li-module tsa litšoantšo le li-photosensor bakeng sa. mefuta e fapaneng ea lisebelisoa. ”
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.

Ho hlola phephetso ena, bo-ramahlale ba tsepamisitse maikutlo ho lokiseng karolo ea "buffer" ea "photodetector" ho ntlafatsa botsitso, ts'ebetso le ho lemoha.

"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.
