Ua hoʻomohala a hōʻike ka poʻe noiʻi i nā kukui ʻōmaʻomaʻo hou e hoʻomoʻi ana i nā photodetectors kūlohelohe i ʻike nui ʻia a kūpono hoʻi me nā ʻano hana CMOS. ʻO ka hoʻokomo ʻana i kēia mau mea ʻike kiʻi hou i loko o nā mea ʻike kiʻi kiʻi silicone hiki ke hoʻohana i nā noi he nui. Aia kēia mau noi i ka nānā ʻana i ka puʻuwai māmā, ka ʻike manamana lima a me nā mea e ʻike ai i ka hele ʻana o nā mea kokoke.
Inā hoʻohana ʻia i nā smartphones a i ʻole nā kiʻi ʻepekema, ʻo ka hapa nui o nā mea ʻike kiʻi i kēia lā e hoʻokumu ʻia i ka ʻenehana CMOS a me nā mea nānā kiʻi inorganic e hoʻololi i nā hōʻailona māmā i nā hōʻailona uila. ʻOiai ʻo nā kiʻi ʻike kiʻi i hana ʻia i nā mea olaola e huki nei i ka manaʻo no ka mea hiki iā lākou ke kōkua i ka hoʻomaikaʻi ʻana i ka naʻau, ua paʻakikī kēia i ka hana ʻana i nā mea nānā kiʻi kūlohelohe kiʻekiʻe.
ʻO ka mea noiʻi alakaʻi ʻo Sungjun Park, mai ke Kulanui ʻo Ajou ma South Korea, i ʻōlelo: "ʻO ka hoʻokomo ʻana i nā mea nānā kiʻi organik i loko o nā mea ʻike kiʻi CMOS i hana nui ʻia e pono ai nā mea hoʻoheheʻe kukui kūlohelohe i maʻalahi ke hana ʻia ma ke ʻano nui a hiki ke ʻike i nā kiʻi ʻike e hana i nā kiʻi ʻoi. i nā kiʻekiʻe kiʻekiʻe i ka pōʻeleʻele. Ua hoʻomohala mākou i nā photodiodes kūlohelohe ʻōmaʻomaʻo a hiki ke hoʻokō i kēia mau koi.
Hōʻike nā mea noiʻi i ka photodetector organik hou i loko o ka puke pai Optica. Ua hana pū lākou i kahi ʻano kiʻi kiʻi RGB hybrid ma o ka hoʻopili ʻana i kahi ʻōmaʻomaʻo ʻōmaʻomaʻo e hoʻomoe ana i ka photodetector organik ma luna o kahi photodiode silicon me nā kānana ʻulaʻula a polū.
Ua ʻōlelo ʻo Kyung-Bae Park, ke alakaʻi hui o ka hui noiʻi mai ka Samsung Advanced Institute of Technology (SAIT) ma South Korea: "Mahalo i ka hoʻokomo ʻia ʻana o kahi papa hoʻopulapula hybrid hybrid, ʻo ka ʻōmaʻomaʻo koho ʻōmaʻomaʻo e hoʻohana ʻia ana ka ʻāpana organik. i kēia mau mea ʻike kiʻi e hōʻemi nui i ke kamaʻilio ʻana ma waena o nā pika kala like ʻole, a hiki i kēia hoʻolālā hou ke hoʻolilo i nā photodiodes organik kiʻekiʻe i mea nui o nā modules kiʻi a me nā photosensors no nā noi like ʻole.
ʻOi aku ka pono o nā mea nānā kiʻi organik
ʻAʻole kūpono ka hapa nui o nā mea kūlohelohe no ka hana nui ma muli o ko lākou ʻike i ka mahana. ʻAʻole hiki iā lākou ke pale i nā wela kiʻekiʻe i hoʻohana ʻia no ka mālama ʻana a i ʻole e lilo i paʻa ke hoʻohana ʻia i nā mahana haʻahaʻa no nā manawa lōʻihi. No ka lanakila ʻana i kēia pilikia, ua kālele ka poʻe ʻepekema i ka hoʻololi ʻana i ka papa pale o ka photodetector e hoʻomaikaʻi i ke kūpaʻa, ka pono, a me ka ʻike. ʻO ka detectability kahi ana o ka maikaʻi o ka ʻike ʻana i nā hōʻailona nāwaliwali. "Ua hoʻokomo mākou i kahi laina keleawe ʻauʻau (BCP): C60 hybrid buffer layer ma ke ʻano he electron transport layer, e hāʻawi ana i ka mea ʻike photodetector i nā waiwai kūikawā, me ka ʻoi aku ka maikaʻi a me ka haʻahaʻa haʻahaʻa o ka pōʻeleʻele, e hōʻemi ana i ka walaʻau," wahi a Sungjun Park. Hiki ke kau ʻia ke kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi me nā kānana ʻulaʻula a polū e hana i kahi ʻike kiʻi hybrid.
Hōʻike nā mea noiʻi e hōʻike ana ke kiʻi kiʻi kiʻi hou i nā helu ʻike e like me nā kiʻi kiʻi kiʻi maʻamau. Hoʻohana paʻa ka mea ʻike no 2 mau hola ma nā mahana ma luna o 150 °C a hōʻike i ka paʻa o ka hana lōʻihi no 30 mau lā ma 85 °C. Hōʻike kēia mau mea nānā kiʻi i ka hana kala maikaʻi.
Ma hope aʻe, hoʻolālā lākou e hana i nā mea nānā kiʻi hou a me nā mea ʻike kiʻi hybrid no nā ʻano noi like ʻole, e like me nā mea kelepona a me nā mea hiki ke hoʻohana ʻia (me nā kiʻi kiʻi CMOS), nā mea ʻike pili, a me nā mea manamana lima ma nā hōʻike.
