Vatsvagiri vakagadzira uye vakaratidza mwenje mutsva wegirinhi unotora pachena organic photodetectors ayo ane hanya zvakanyanya uye anoenderana neCMOS nzira dzekugadzira. Kubatanidza aya mafotodetectors matsva musilicone hybrid image sensors kunogona kubatsira kune akawanda maapplication. Aya maapplication anosanganisira light-based heart rate monitoring, kucherechedzwa kweminwe uye zvishandiso zvinoona kuvepo kwezvinhu zviri pedyo.
Ingave ichishandiswa mumafoni efoni kana esainzi makamera, mazhinji ekufungidzira ma sensors nhasi akavakirwa paCMOS tekinoroji uye inorganic photodetectors inoshandura masaini masaini kuita masaini emagetsi. Kunyangwe mafotodetectors akagadzirwa neorganic zvinhu ari kukwezva kutarisisa nekuti anogona kubatsira kuvandudza kunzwisiswa, kusvika parizvino zvaratidza kunetsa kugadzira yakakwirira-performance organic photodetectors.
Co-lead muongorori Sungjun Park, wekuAjou University kuSouth Korea, akati: "Kuisa maoga fotodetectors mumisikirwo yemifananidzo yeCMOS inogadzirwa zvakanyanya kunoda maorganic light absorbers ayo ari nyore kugadzira pamwero mukuru uye anokwanisa kucherechedzwa nemufananidzo wakajeka kugadzira mifananidzo yakapinza. pakakwirira furemu mitengo murima. Isu takagadzira akajeka, akasvibira-sensitive organic photodiodes anogona kuita izvi zvinodiwa. "
Vatsvagiri vanotsanangura iyo nyowani organic photodetector mujenari Optica. Ivo zvakare vakagadzira iyo yakasanganiswa RGB yekufungidzira sensor nekusimudzira yakajeka yegirini inonwisa organic photodetector pane silicon photodiode ine tsvuku uye bhuruu mafirita.
Kyung-Bae Park, mutungamiriri wechikwata chekutsvagisa kubva kuSamsung Advanced Institute of Technology (SAIT) muSouth Korea, akati: “Tinotenda nekuunzwa kwehybrid organic buffer layer, iyo green-selective light-absorbing organic layer yakashandiswa. mune aya ma sensors emifananidzo anoderedza zvakanyanya crosstalk pakati pemapikisi emavara akasiyana, uye dhizaini nyowani iyi inogona kuita yakakwira-performance organic photodiodes chikamu chikuru chekufungidzira mamodule uye mafotosensor kune akasiyana maapplication. ”
Zvimwe zvinoshanda organic photodetectors
Mazhinji organic zvinhu hazvina kukodzera kugadzirwa kwakawanda nekuda kwekunzwa kwavo kune tembiricha. Ivo vangave havakwanise kumirisana nekupisa kwakanyanya kunoshandiswa mushure mekurapa kana kuve isina kugadzikana kana ichishandiswa pamhepo tembiricha kwenguva yakareba. Kukunda dambudziko iri, masayendisiti akatarisana nekugadzirisa iyo buffer layer yephotodetector kuti ivandudze kugadzikana, kushanda nesimba, uye kuona. Detectability chiyero chekuti sei sensor inogona kuona isina simba masaini. "Takaunza tambo yekugezesa yemhangura (BCP): C60 hybrid buffer layer seye electron transport layer, iyo inopa organic photodetector yakakosha zvivakwa, zvinosanganisira kugona kwepamusoro uye kuderera kwakanyanya kwakasviba, izvo zvinoderedza ruzha," inodaro Sungjun Park. Iyo photodetector inogona kuiswa pasilicon photodiode ine tsvuku uye yebhuruu mafirita kugadzira iyo yakasanganiswa mufananidzo sensor.
Vatsvagiri vanoratidza kuti iyo nyowani photodetector inoratidza mareti ekuona anofananidzwa neaya akajairwa silicon photodiodes. Iyo detector yakashanda zvakatsiga kwemaawa maviri patembiricha iri pamusoro pe150 °C uye yakaratidza kugadzikana kwekushanda kwenguva refu kwemazuva makumi matatu pa85 °C. Aya mafotodetectors anoratidzawo kuita kwakanaka kwemavara.
Tevere, ivo vanoronga kugadzirisa nyowani mafotodetectors uye mahybrid image sensors kune akasiyana maapplication, senge nharembozha uye inopfekwa sensors (kusanganisira CMOS mifananidzo ma sensors), ma sensors epedyo, uye zvigunwe zvemunwe pazviratidziro.
