Vatsvagiri kubva kuM.V. Lomonosov Moscow State University (MSU) vakaronga tekinoroji nyowani ichabatsira kuvandudza kushanda kwemasolar panels.
Masayendisiti anga achiedza ne perovskite solar masero. Perovskite iminerari isingawanzo kuwanikwa paPasi penyika, calcium titanate. Kubva pakusikwa kwekutanga kweprototype ye perovskite solar cell muna 2009, zvigadzirwa zvakadaro zvakaratidza kukurumidza kuwedzera kwekushanda: kukosha uku kunodarika 25%.
Kuti uwedzere kuwedzera kushanda, zvinorongedzerwa kuumba mutsara pamusoro pechigadziko chinopinza chiedza. Isu tiri kutaura nezve chimiro chealternating protrusions uye grooves: nekuda kweizvi, mwenje unonyatso kupararira pane zvisiri izvo uye zviri nani kunyudzwa, izvo zvinoita kuti zvikwanise kuwedzera kushanda zvakanaka.
Nyanzvi dzeMoscow State University dzakagadzira nzira itsva yekugadzira "finned" masero ezuva. Iyo tekinoroji inosanganisira kushandiswa kwemethyl ammonium polyiodides: makomisheni akadaro ari munzvimbo yemvura pane tembiricha yekamuri uye anoita zvakanyanya nesimbi inotungamira. Aya maficha anoita kuti zvive nyore kuumba perovskite light-absorbing layer ine yakapihwa pamusoro microstructure, pane kuigadzirisa mushure mekugadzirwa, sezvinoitwa kakawanda.
"Maitiro atakagadzira anobva pane chiitiko chekukura kwekristaro munzvimbo yakaganhurirwa. Kuti uwane perovskite layer ine imwe nzvimbo yekuzorora, madonhwe akati wandei e reactive polyiodides akaiswa pamusoro pefirimu resimbi lead uye akatsikirirwa nechitambi chine zororo rakapihwa, "vanotsanangura kudaro.
Iyo tekinoroji yakarongwa inobvumira kwete kungoita nyore, asiwo kukurumidza kusikwa kwe "finned" masero ezuva. Zvinotora chaizvo maminetsi mashoma kuumba zororo rinodiwa.
