Ngakhale kuti mapanelo adzuwa amadalira kuwala kwa dzuwa kuti apange magetsi, kutentha kumatha kuchepetsa mphamvu ya ma cell a dzuwa. Gulu la ofufuza ochokera ku South Korea lapeza yankho lodabwitsa: mafuta a nsomba.
Pofuna kuteteza ma cell a dzuwa kuti asatenthedwe, ofufuza apanga makina otenthetsera a photovoltaic omwe amagwiritsa ntchito zamadzimadzi kusefa kutentha ndi kuwala kochulukirapo. Pochotsa kuwala kwa ultraviolet komwe kumatha kutenthetsa ma cell a solar, zosefera zamadzimadzi zimatha kusunga ma cell adzuwa kukhala ozizira ndikusunga kutentha kuti zigwiritsidwe ntchito mtsogolo.
Makina otenthetsera a photovoltaic amatha kugwiritsa ntchito madzi kapena nanoparticle monga zosefera zamadzimadzi. Vuto ndiloti njira zamadzi ndi nanoparticle sizimasefa bwino kwambiri kuwala kwa ultraviolet.
"Decoupled photovoltaic matenthedwe machitidwe ntchito zosefera madzi kuti kuyamwa wavelengths osagwira ntchito monga ultraviolet, zooneka ndi pafupi-infuraredi cheza. Komabe, madzi, wotchuka fyuluta, sangathe kuyamwa cheza ultraviolet bwino, kuchepetsa dongosolo ntchito,"- Korea Maritime University (KMOU) . Gulu la ofufuza ochokera ku CleanTechnica linafotokoza.
Gulu la KMOU lapeza kuti mafuta a nsomba ndi abwino kwambiri pakusefa kuwala kochulukirapo. Ngakhale kuti njira zambiri zochepetsera madzi zimagwira ntchito pa 79.3%, mafuta a nsomba opangidwa ndi gulu la KMOU adapeza 84.4%. Poyerekeza, gululo lidayeza cell ya solar yomwe imagwira ntchito pa 18% komanso makina otenthetsera adzuwa omwe amagwira ntchito pa 70.9%.
"Zosefera za emulsion za "[mafuta a nsomba] zimagwira bwino ntchito ya ultraviolet, yowoneka ndi pafupi ndi infrared wavelengths zomwe sizikuthandizira kupanga mphamvu za photovoltaic modules ndikuzisintha kukhala mphamvu zotentha," lipoti la gululo likutero.
Makina otentha a photovoltaic amatha kupereka kutentha ndi magetsi. "Dongosolo lofunsidwa limatha kugwira ntchito pazifukwa zina komanso zachilengedwe. Mwachitsanzo, m'chilimwe, madzi amadzimadzi amadzimadzi amatha kudumphira kuti apititse patsogolo mphamvu zamagetsi, ndipo m'nyengo yozizira, fyuluta yamadzimadzi imatha kugwira mphamvu yotentha yotentha," gulu la KMOU likutero.
Pamene kufunikira kwa mphamvu zowonjezereka kukukula, ofufuza akugwira ntchito mwakhama kuti mphamvu za dzuwa zikhale zotsika mtengo, zokhazikika komanso zogwira mtima. Ma cell a solar a perovskite olimba kwambiri ndi okwera mtengo komanso otsika mtengo, ndipo ma nanoparticles a silicon amatha kusintha kuwala kocheperako kukhala kopatsa mphamvu kwambiri. Zomwe gulu la KMOU lapeza zikuyimira sitepe lina lakutsogolo popanga mphamvu zamagetsi kukhala zotsika mtengo.
Lowani m'makalata athu aulere kuti mulandire zosintha zamlungu ndi mlungu pazatsopano zatsopano zomwe zikusintha miyoyo yathu ndikupulumutsa dziko lapansi.
