Asayansi a Ryazan ochokera ku yunivesite ya Yesenin State adalandira chilolezo chaukadaulo chomwe chingachepetse kwambiri mtengo wopangira ma solar.
Malinga ndi pulofesa wothandizana nawo ku yunivesite Vadim Tregulov, zokutira zomwe zimagwiritsidwa ntchito pano, monga magnetron sputtering, ndizokwera mtengo kwambiri. Dipatimentiyi inapeza njira yogwiritsira ntchito mafilimu ochepa kwambiri a silicon ya porous, opangidwa ndi njira zosavuta za mankhwala kapena electrochemical. Chifukwa cha kugwiritsidwa ntchito kwa chinthu ichi, mtengo wopangira magetsi a dzuwa umachepetsedwa ndi pafupifupi 30%, izi zidzalola kuti apikisane ndi omwe amapanga magetsi a dzuwa ochokera ku China.
“Chimodzi mwa zifukwa zofunika kwambiri zomwe zikulepheretsa kukula kwa mphamvu ya dzuwa ndi kukwera mtengo kwa magetsi a dzuŵa. Ogwira ntchito ku dipatimentiyi ali ndi chilolezo chogwiritsa ntchito mafilimu oonda a porous silicon panthawi imodzi ngati anti-reflection coating ndi wosanjikiza woyamwa kuwala. Kugwiritsiridwa ntchito kwa chinthu ichi, chomwe sichifuna kugwiritsa ntchito zipangizo zamtengo wapatali, kumatithandiza kuchepetsa mtengo wopangira ndi 30% ndikupikisana ndi omwe amapanga magetsi a dzuwa ochokera ku China, "adatero mnzake. pulofesa.
Komabe, yankho ili lili ndi drawback yaikulu. Chowonadi ndi chakuti silicon ya porous imakhala yosakhazikika ndipo imataya katundu wake woyambirira. Chotsatira chake, chitukuko chachikulu cha asayansi ndi cholinga chofuna kupeza njira zothetsera vutoli ndikuonetsetsa kuti katundu wa chinthucho ndi wolimba.
Akuti njira yovomerezeka ingagwiritsidwe ntchito osati pakupanga mafakitale a maselo a dzuwa, komanso kupanga tcheru kwambiri, zowunikira zothamanga kwambiri komanso zowunikira za terahertz.
