Hoʻomaikaʻi ka mālama ʻana i ka Vitamin C i ke kūpaʻa ʻana o nā cell solar inverted

Ua ʻimi kahi hui o nā mea noiʻi mai ke Kulanui o Southern Denmark (SDU) e hoʻohālikelike i nā holomua i hana ʻia i ka hoʻololi ʻana i ka mana no nā cell solar organik (OPV) i hana ʻia memea ʻae ʻole-fullerene (NFA)nā mea me ka hoʻomaikaʻi kūpaʻa.

Ua koho ka hui i ka ʻakika ascorbic, i ʻike mau ʻia ʻo ka huaʻa C, a ua hoʻohana ʻia ia ma ke ʻano he papa passivation ma waena o kahi zinc oxide (ZnO) electron transport layer (ETL) a me ka papa photoactive o loko o nā pūnaewele NFA OPV i hana ʻia me kahi waihona mea hoʻohuli a me kahi. polimer semiconducting (PBDB-T:IT-4F).

Ua kūkulu ka poʻe ʻepekema i ke kelepona me kahi papa indium tin oxide (ITO), ka ZnO ETL, ka papa vitamina C, ka PBDB-T: IT-4F absorber, kahi molybdenum oxide (MoOx) papa koho koho, a me kahi kālā (Ag). ) pili metala.

Ua ʻike ka hui e hoʻopuka ka ascorbic acid i kahi hopena photostabilizing, e hōʻike ana i ka hana antioxidant e hoʻohaʻahaʻa i nā kaʻina degradative e puka mai ana mai ka ʻike ʻana i ka oxygen, ka māmā a me ka wela. ʻO nā ho'āʻo, e like me ka ultraviolet-visible absorption, impedance spectroscopy, light-dependent voltage a me nā ana o kēia manawa, ua hōʻike pū ʻia e hōʻemi ka huaora C i ka photobleaching o nā molekala NFA a hoʻopaʻa i ka hoʻohui hou ʻana, ʻike ʻia ka noiʻi.

Ua hōʻike kā lākou hōʻike ʻana, ma hope o 96 mau hola o ka hoʻoneʻe ʻana i ka photodegradation ma lalo o 1 Sun, ua paʻa nā mea hoʻopili i loaʻa i ka vitamin C interlayer i ka 62% o kā lākou kumu waiwai, me nā mea kuhikuhi e mālama wale ana i 36%.

Ua hōʻike pū ʻia nā hopena ʻaʻole i hiki mai ka loaʻa ʻana o ke kūpaʻa ma ke kumu kūʻai o ka pono. Ua loaʻa i ka mea hoʻokūkū ka mana hoʻololi mana o 9.97 %, he 0.69 V ka wehe ʻana, kahi pōkole pōkole o kēia manawa o 21.57 mA/cm2, a me kahi mea hoʻopiha piha o 66%. ʻO nā mea kuhikuhi i loaʻa ʻole ka huaora C, hōʻike ʻia he 9.85 % ka maikaʻi, kahi puʻupuʻu hāmama o 0.68V, kahi manawa pōkole o 21.02 mA/cm2, a me kahi helu hoʻopiha o 68%.

Ke nīnau ʻia e pili ana i ka hiki ke kūʻai aku a me ka scalability, ʻo Vida Engmann ke poʻo i kahi hui ma kaKikowaena no nā kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻiʻoniʻoni a me nā mea ikehu kiʻiʻoniʻoni lahilahi (SDU CAPE), i haʻi aku i ka pv magazine, "ʻO kā mākou mau mea hana i kēia hoʻokolohua ʻo 2.8 mm2 a me 6.6 mm2, akā hiki ke hoʻonui ʻia i kā mākou roll-to-roll lab ma SDU CAPE kahi mākou e hana mau ai i nā modula OPV."

Ua hoʻokūpaʻa ʻo ia e hiki ke hoʻonui ʻia ke ʻano hana, e kuhikuhi ana i ka papa interfacial he "hui kūʻai ʻole i hiki ke hoʻoheheʻe ʻia i nā solvents maʻamau, no laila hiki ke hoʻohana ʻia i loko o kahi kaʻina hana ʻōwili e like me ke koena o nā papa" he kelepona OPV.

ʻIke ʻo Engmann i ka hiki ke hoʻohui i nā mea hoʻohui ma mua o OPV i nā ʻenehana kelepona o nā hanauna ʻekolu, e like me ka perovskite solar cell a me ka dye-sensitized solar cell (DSSC). "ʻO nā ʻenehana semiconductor-based organik/hybrid, e like me DSSC a me perovskite solar cell, loaʻa nā pilikia paʻa like me nā cell solar organik, no laila aia kahi manawa kūpono e hiki ai iā lākou ke kōkua i ka hoʻoponopono ʻana i nā pilikia paʻa i kēia mau ʻenehana pū kekahi," wahi āna.

Ua hōʻike ʻia ke kelepona ma ka pepa "Huaola C no ke Kiʻi-Stable Non-fullerene-acceptor-Based Organic Solar Cells,” i hoopukaia maACS i hoʻohana ʻia i nā mea i hoʻohana ʻia.ʻO ka mea kākau mua o ka pepa ʻo SDU CAPE's Sambathkumar Balasubramanian. Ua komo ka hui i nā mea noiʻi mai SDU a me Rey Juan Carlos University.

Ke nānā nei i mua he hoʻolālā ka hui no ka noiʻi hou ʻana i nā ala hoʻokūpaʻa me ka hoʻohana ʻana i nā antioxidants kūlohelohe. "I ka wā e hiki mai ana, e hoʻomau mākou i ka noiʻi ʻana ma kēia ʻaoʻao," wahi a Engmann e pili ana i ka noiʻi hoʻohiki ʻana i kahi papa hou o nā antioxidants.
