Ua hoʻomohala a hōʻike nā kānaka noiʻi i nā mea ʻike kiʻi organik ʻōmaʻomaʻo hou e omo ana i ke kukui ʻōmaʻomaʻo 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 hybrid silicone hiki ke lilo i mea pono no nā noi he nui. ʻO kēia mau noi e pili ana i ka nānā ʻana i ka helu o ka puʻuwai e pili ana i ka mālamalama, ka ʻike ʻana i nā manamana lima a me nā mea hana e ʻike ai i ke alo o nā mea kokoke.
Inā hoʻohana ʻia i loko o nā kelepona akamai a i ʻole nā kāmela ʻepekema, ʻo ka hapa nui o nā mea ʻike kiʻi i kēia lā ua hoʻokumu ʻia ma ka ʻenehana CMOS a me nā mea ʻike kiʻi inorganic e hoʻololi i nā hōʻailona kukui i nā hōʻailona uila. ʻOiai ʻo nā mea ʻike kiʻi i hana ʻia me nā mea organik e huki nei i ka manaʻo no ka mea hiki iā lākou ke kōkua i ka hoʻomaikaʻi ʻana i ka ʻike, ua paʻakikī a hiki i kēia manawa ke hana i nā mea ʻike kiʻi organik hana kiʻekiʻe.
Ua ʻōlelo ʻo Sungjun Park, ke alakaʻi noiʻi, mai ke Kulanui ʻo Ajou ma Kōlea Hema: "ʻO ka hoʻokomo ʻana i nā photodetectors organik i loko o nā mea ʻike kiʻi CMOS i hana nui ʻia e pono ai nā mea hoʻomoʻa kukui organik e maʻalahi ke hana ma kahi pae nui a hiki ke ʻike i ke kiʻi ʻoi e hana i nā kiʻi ʻoi ma nā wikiwiki kiʻi kiʻekiʻe i ka pōʻeleʻele. Ua hoʻomohala mākou i nā photodiodes organik aniani, ʻōmaʻomaʻo-sensitive e hiki ke hoʻokō i kēia mau koi."
Ua wehewehe nā kānaka noiʻi i ka mea ʻike kiʻi organik hou ma ka puke pai ʻo Optica. Ua hana pū lākou i kahi mea ʻike kiʻi RGB hybrid ma ke kau ʻana i kahi mea ʻike kiʻi organik ʻōmaʻomaʻo moakaka ma luna o kahi photodiode silicon me nā kānana ʻulaʻula a me ka uliuli.
Ua ʻōlelo ʻo Kyung-Bae Park, ke alakaʻi hui o ka hui noiʻi mai ka Samsung Advanced Institute of Technology (SAIT) ma Kōlea Hema: "Mahalo i ka hoʻolauna ʻana o kahi papa buffer organic hybrid, ʻo ka papa organik ʻōmaʻomaʻo-selective light-absorbing i hoʻohana ʻia i loko o kēia mau mea ʻike kiʻi e hōʻemi nui i ka crosstalk ma waena o nā pikela kala like ʻole, a hiki i kēia hoʻolālā hou ke hoʻolilo i nā photodiodes organic hana kiʻekiʻe i ʻāpana nui o nā modula kiʻi a me nā photosensors no nā ʻano noi like ʻole."
Nā mea ʻike kiʻi organik hou aku
ʻAʻole kūpono ka hapa nui o nā mea olaola no ka hana nui ʻana ma muli o ko lākou ʻike i ka mahana. ʻAʻole hiki iā lākou ke kū i nā mahana kiʻekiʻe i hoʻohana ʻia no ka mālama ʻana ma hope o ka mālama ʻana a i ʻole lilo i mea paʻa ʻole ke hoʻohana ʻia i nā mahana kūpono no ka manawa lōʻihi. No ka lanakila ʻana i kēia pilikia, ua kālele nā ʻepekema i ka hoʻololi ʻana i ka papa buffer o ka photodetector e hoʻomaikaʻi i ke kūpaʻa, ka pono, a me ka ʻike ʻana. ʻO ka detectability kahi ana o ka maikaʻi o ka hiki i kahi sensor ke ʻike i nā hōʻailona nāwaliwali. "Ua hoʻolauna mākou i kahi laina keleawe ʻauʻau (BCP): C60 hybrid buffer layer ma ke ʻano he papa lawe electron, e hāʻawi ana i ka photodetector organik i nā waiwai kūikawā, me ka ʻoi aku ka maikaʻi a me ke au pouli haʻahaʻa loa, kahi e hōʻemi ai i ka walaʻau," wahi a Sungjun Park. Hiki ke kau ʻia ka photodetector ma kahi photodiode silicon me nā kānana ʻulaʻula a me ka uliuli e hana i kahi sensor kiʻi hybrid.
Ua hōʻike nā kānaka noiʻi ua hōʻike ka photodetector hou i nā helu ʻike e like me nā photodiodes silicon maʻamau. Ua hana paʻa ka mea ʻike no 2 mau hola ma nā mahana ma luna o 150 °C a ua hōʻike i ka paʻa hana lōʻihi no 30 mau lā ma 85 °C. Hōʻike pū kēia mau photodetectors i ka hana kala maikaʻi.
ʻO ka mea aʻe, hoʻolālā lākou e hoʻopilikino i nā photodetectors hou a me nā sensor kiʻi hybrid no nā ʻano noi like ʻole, e like me nā sensor kelepona a me nā mea hiki ke hoʻohana ʻia (me nā sensor kiʻi CMOS), nā sensor kokoke, a me nā mea hana manamana lima ma nā hōʻike.
