Asayansi aku Spain ochokera ku Institute of Materials Science and Technology (ICMS) ku Seville otukuka Selo ya dzuwa yosakanizidwa yochokera ku perovskite, yomwe imatha kusintha nthawi imodzi kuwala kwa dzuwa ndi mphamvu ya madontho amvula omwe akugwa kukhala magetsi. Ukadaulowu umaphatikiza mphamvu yachilengedwe ya photovoltaic pa kuwala kwa dzuwa ndi mphamvu ya triboelectric pa madontho amvula. Kwenikweni, ndi yankho loyenera nyengo yonse.
Lingaliro loyambira ndi losavuta: kupanga chipangizo chogwira ntchito zambiri chomwe chimagwira ntchito bwino kwambiri nyengo zosiyanasiyana, makamaka m'madera omwe mvula imagwa pafupipafupi. Kapangidwe ka selo kamagwiritsa ntchito gawo la perovskite kuti lipange mphamvu ya dzuwa, pamwamba pake pali gawo laling'ono la polymer lopangidwa ndi fluorinated la CFₓ, lomwe lili ndi zinthu zingapo zofunika: kuwonekera bwino kwambiri (kupitirira 90%), kusowa kwa madzi, komanso kuthekera kopanga mphamvu ya triboelectric.
Chitsulo choteteza ichi, chomwe chimayikidwa kutentha kwa chipinda mu vacuum pogwiritsa ntchito plasma spray, chimateteza perovskite yofatsa ku chinyezi pomwe nthawi yomweyo imalola kusonkhanitsa mphamvu kuchokera ku mvula. Dontho la mvula likagunda pamwamba ndi kupatukana, kulekanitsidwa kwa kukhudzana ndi mphamvu kumachitika pakati pa zinthuzo, zomwe zimapangitsa kuti kugunda kwamagetsi kuchitike.
Zitsanzo zoyesera zinawonetsa mphamvu ya photovoltaic ya 17,9%. Gawo la triboelectric la chipangizocho linawonetsa magwiridwe antchito odabwitsa: magetsi otseguka okwana 110 V pa dontho lililonse ndi mphamvu yayikulu yokwana pafupifupi 4 mW/m². Mu hybrid mode, pa theka la kuwala kwa dzuwa (500 W/m²), mphamvu yamagetsi yochepa ya 11,6 mA/m² inapezeka, ndipo mphamvu yapamwamba yochokera ku madontho inali mpaka 12 V. Ofufuzawo adapanganso chiwonetsero momwe selo yosakanikirana idayatsa supercapacitor ndikuyendetsa chingwe cha LED kudzera mu chosinthira.
Ntchitoyi, yomwe ikuchitika ndi mapulojekiti a 3DScavengers ndi Drop Ener mothandizidwa ndi European Research Council ndi Next Generation Fund, ikutsegula chitseko cha mapanelo a dzuwa osinthasintha. Ngakhale kuti kuwala kwa dzuwa kumaperekabe mphamvu yayikulu, mphamvu yowonjezera yochokera ku mvula imafulumizitsa kuyatsa kwa mabatire munyengo yamitambo. Komabe, kukulitsa ukadaulo kupitirira zitsanzo za labotale kumakhalabe kovuta ndipo kumafuna kafukufuku wowonjezereka.
