Kuvandudza kushanda kwemasero ezuva kuti uwane rusununguko kubva kune fossil mafuta emagetsi masosi ndiyo inonyanya kutariswa mukutsvaga kwesolar cell. Chikwata chinotungamirwa nenyanzvi yefizikisi Dr. Felix Lang kubva kuYunivhesiti yePotsdam, pamwe chete naProf. Lei Meng naProf Yongfang Li vanobva kuChinese Academy of Sciences muBeijing, vakabudirira kubatanidza perovskite nemasikirini emagetsi kuti vagadzire tandem solar cell inowana rekodhi rekodhi, sezvakataurwa mumagazini yesainzi Nature.
Iyi nzira inosanganisira kusanganiswa kwezvinhu zviviri zvinosarudza kutora mafupi uye marefu marefu-kunyanya, yebhuruu / yegirini uye tsvuku / infrared nzvimbo dze spectrum-zvichidaro optimize kushandiswa kwezuva. Sechinyakare, iyo inonyanya kushanda tsvuku / infrared inonwisa zvikamu mumasero ezuva zvakabva kune zvakajairwa zvinhu zvakaita sesilicon kana CIGS (copper indium gallium selenide). Nekudaro, izvi zvigadzirwa zvinowanzoda yakanyanya kupisa tembiricha, zvichikonzera yakakosha kabhoni tsoka.
Muchinyorwa chavo chechangobva kuitika muNature, Lang nevamwe vake vanosanganisa maviri anovimbisa solar cell tekinoroji: perovskite uye organic solar masero, anogona kugadziriswa pakudzika kwakadzika uye ane yakaderedzwa kabhoni. Kuwana kushanda kunoshamisa kwe25.7% nemusanganiswa mutsva uyu raive basa rakaoma, sezvakataurwa naFelix Lang, uyo akatsanangura, "Budiriro iyi yakagoneswa chete nekubatanidza kufambira mberi kuviri kwakakosha." Kubudirira kwekutanga kwaive kuumbwa kwetsva tsvuku/infrared inotora organic solar cell naMeng naLi, iyo inowedzera kugona kwayo kunyura mukati meiyo infrared renji. Lang akaenderera mberi achiti, "Zvisinei, tandem solar masero akatarisana nemiganhu nekuda kweiyo perovskite layer, iyo inorasikirwa nekurasika kwakanyanya kana yakagadzirirwa kutora zvakanyanya zvikamu zvebhuruu negirinhi zvesolar spectrum.
