ʻOiai ke hilinaʻi nei nā panela lā i ka lā e hoʻohua ai i ka uila, hiki i ka wela ke hoʻemi maoli i ka pono o nā cell solar. Ua loaʻa i kahi hui o nā mea noiʻi mai South Korea kahi hopena kamahaʻo: ʻaila iʻa.
No ka pale ʻana i ka wela o ka lā, ua kūkulu nā mea noiʻi i nā ʻōnaehana wela photovoltaic decoupled e hoʻohana ana i nā wai e kānana i ka wela a me ka māmā. Ma ka hoʻopau ʻana i ke kukui ultraviolet hiki ke hoʻomāhuahua i nā pūnaewele lā, hiki i nā kānana wai ke mālama i ka maʻalili o ka lā i ka wā e mālama ai i ka wela no ka hoʻohana ʻana ma hope.
Hoʻohana maʻamau nā ʻōnaehana wela photovoltaic decoupled i ka wai a i ʻole nā ​​mea nanoparticle e like me nā kānana wai. ʻO ka pilikia, ʻaʻole kānana maikaʻi loa ka wai a me ka nanoparticle i nā hihi ultraviolet.
"Hoʻohana nā ʻōnaehana thermal photovoltaic i hoʻokaʻawale ʻia i nā kānana wai e hoʻomoʻa i nā hawewe kūpono ʻole e like me nā kukui ultraviolet, ʻike ʻia a kokoke i ka infrared. Akā naʻe, ʻaʻole hiki i ka wai, kahi kānana kaulana, ke komo pono i nā kukui ultraviolet, e kaupalena ana i ka hana o ka ʻōnaehana, "- Korea Maritime University (KMOU) . Ua wehewehe kekahi hui o nā mea noiʻi mai CleanTechnica.
Ua ʻike ka hui KMOU he maikaʻi loa ka ʻaila iʻa i ke kānana ʻana i nā kukui keu. ʻOiai ʻo ka hapa nui o nā ʻōnaehana hoʻokaʻawale wai ma ka 79.3% ka maikaʻi, ʻo ka ʻōnaehana ʻaila iʻa i hoʻomohala ʻia e ka hui KMOU ua loaʻa iā 84.4% ka maikaʻi. No ka hoʻohālikelike ʻana, ua ana ka hui i kahi cell solar off-grid e hana ana ma 18% pono a me kahi ʻōnaehana wela solar off-grid e hana ana ma 70.9% pono.
"ʻO nā kānana emulsion [ʻaila iʻa] e hoʻopili pono i nā nalu ultraviolet, ʻike ʻia a kokoke i ka infrared ʻaʻole kōkua i ka hana ʻana i ka ikehu o nā modula photovoltaic a hoʻololi iā lākou i ka ikehu wela," wahi a ka hui.
Hiki i nā ʻōnaehana wela photovoltaic decoupled ke hāʻawi i ka wela a me ka uila. "Hiki i ka ʻōnaehana i manaʻo ʻia ke hana ma lalo o kekahi mau koi a me nā kūlana kaiapuni. No ka laʻana, i ke kauwela, hiki ke kāpae ʻia ka wai i loko o ka kānana wai e hoʻonui i ka hana mana, a i ka hoʻoilo, hiki i ka kānana wai ke hopu i ka ikehu wela no ka hoʻomehana ʻana, "hōʻike ka hui KMOU.
Ke ulu nei ka noi no ka ikehu hou, ke hana luhi nei nā mea noiʻi e hoʻolilo i ka ikehu o ka lā i ʻoi aku ka maʻalahi, hoʻomau a maikaʻi. Hiki ke hoʻololi i nā kukui uila haʻahaʻa i nā kukui uila kiʻekiʻe. Hōʻike ka ʻike a ka hui KMOU i kahi ʻanuʻu ʻē aʻe i mua o ka hoʻonui ʻana i ka pono o ka ikehu.
E hoʻopaʻa inoa no kā mākou nūpepa manuahi e loaʻa i nā mea hou i kēlā me kēia pule e pili ana i nā mea hou e hoʻomaikaʻi nei i ko mākou ola a mālama i ka honua.
