Vaongorori vakagadzira uye vakaratidza chiedza chitsva chegirini chinotora mafoto detector echisikigo anopenya uye anoenderana nenzira dzekugadzira dzeCMOS. Kuisa mafoto detector matsva aya mumasensa emifananidzo emhando yesilicone hybrid kunogona kubatsira kune akawanda maapplication. Maapplication aya anosanganisira kutarisa kurova kwemoyo zvichibva pachiedza, kuziva zvigunwe uye zvishandiso zvinoona kuvapo kwezvinhu zviri pedyo.
Kunyangwe zvichishandiswa mumafoni kana makamera esainzi, masensa mazhinji ekufungidzira mifananidzo nhasi akavakirwa patekinoroji yeCMOS uye mafoto detector asina kugadzirwa anoshandura masaini echiedza kuita masaini emagetsi. Kunyangwe mafoto detector akagadzirwa nezvinhu zvakasikwa ari kukwezva kutariswa nekuti anogona kubatsira kuvandudza kunzwisisika, kusvika pari zvino zvave zvakaoma kugadzira mafoto detector emhando yepamusoro anoshanda zvakanaka.
Mumwe wevaongorori vakuru Sungjun Park, wekuAjou University muSouth Korea, akati: "Kuisa maphotodetector eorganic mumaCMOS image sensors anogadzirwa akawanda kunoda ma organic light absorbers ari nyore kugadzira pamwero mukuru uye anokwanisa kuona mifananidzo zvakajeka kuti abudise mifananidzo yakapinza padanho repamusoro murima. Takagadzira maphotodiode eorganic akajeka, anonzwa girini anogona kusangana nezvinodiwa izvi."
Vaongorori vanotsanangura nezvechinhu chitsva chinoona mifananidzo yeorganic mumagazini yeOptica. Vakagadzirawo sensor yehybrid RGB imaging nekuisa chinhu chinoona mifananidzo yeorganic chinopinza mifananidzo yeorganic chinopenya pasilicon photodiode ine mafirita matsvuku nebhuruu.
Kyung-Bae Park, mumwe wevatungamiri vechikwata chekutsvagisa kubva kuSamsung Advanced Institute of Technology (SAIT) muSouth Korea, akati: “Nekuda kwekuunzwa kwehybrid organic buffer layer, green-selective organic layer inoshandiswa muma sensors aya emifananidzo inoderedza zvakanyanya kutaurirana pakati pemapikiseli emavara akasiyana, uye dhizaini itsva iyi inogona kuita kuti ma photodiode eorganic anoshanda zvakanyanya ave chikamu chikuru chema modules emifananidzo uye ma photosensors ekushandisa kwakasiyana-siyana.”
Zvimwe zvinoongorora mafoto zveorganic zvinoshanda
Zvizhinji zvezvinhu zvakasikwa hazvina kukodzera kugadzirwa zvakanyanya nekuda kwekunzwa kwazvinoita tembiricha. Hazvigone kutsungirira tembiricha yepamusoro inoshandiswa mushure mekurapwa kana kuti hazvigone kugadzikana kana zvikashandiswa patembiricha dziri pakati nepakati kwenguva yakareba. Kuti vakunde dambudziko iri, masayendisiti akatarisana nekugadzirisa buffer layer ye photodetector kuti vavandudze kugadzikana, kushanda zvakanaka, uye kuonekwa. Kuonekwa kwechinhu ichi chiyero chekuti sensor inogona sei kuona zviratidzo zvisina simba. "Takaunza bath copper line (BCP) : C60 hybrid buffer layer se electron transport layer, iyo inopa organic photodetector hunhu hwakakosha, kusanganisira kushanda zvakanaka uye dark current yakaderera kwazvo, iyo inoderedza ruzha," anodaro Sungjun Park. Photodetector inogona kuiswa pasilicon photodiode ine mafirita matsvuku nebhuruu kugadzira hybrid image sensor.
Vaongorori vanoratidza kuti photodetector itsva inoratidza mwero wekuona wakafanana newema silicon photodiodes echinyakare. Detector iyi yakashanda zvakanaka kwemaawa maviri patembiricha iri pamusoro pe150 °C uye yakaratidza kugadzikana kwenguva refu kwekushanda kwemazuva makumi matatu pa85 °C. Ma photodetector aya anoratidzawo kushanda zvakanaka kwemavara.
Tevere, vanoronga kugadzirisa ma photodetector matsva nema hybrid image sensors kuti zvishandiswe zvakasiyana-siyana, zvakaita se mobile sensors nezvinopfekwa (kusanganisira CMOS image sensors), proximity sensors, uye fingerprint devices dziri pazviratidziro.
