Ukuthuthukisa ukusebenza kahle kwamaseli elanga ukuze bathole inkululeko emithonjeni yamandla kaphethiloli wezinto ezimbiwa phansi kugxilwe kakhulu ocwaningweni lwamaseli elanga. Ithimba eliholwa isazi sefiziksi uDkt. Felix Lang waseNyuvesi yasePotsdam, kanye noProf. Lei Meng kanye noProf. Yongfang Li ovela e-Chinese Academy of Sciences e-Beijing, lihlanganise ngempumelelo i-perovskite nama-absorber ephilayo ukuze kwakhiwe iseli lelanga le-tandem elifinyelela amazinga okusebenza kahle, njengoba kubikwe kumagazini wesayensi we-Nature.
Le ndlela ihlanganisa inhlanganisela yezinto ezimbili ezimunca ngokukhetha ubude beza beza obufushane namade—ikakhulukazi, izindawo eziluhlaza okwesibhakabhaka/eziluhlaza kanye nebomvu/ebomvu/ebomvu—ngalokho kuthuthukisa ukusetshenziswa kokukhanya kwelanga. Ngokwesiko, izingxenye ezisebenza kahle kakhulu zokumunca okubomvu/kwe-infrared kumaseli elanga zivela ezintweni ezivamile ezifana ne-silicon noma i-CIGS (i-copper indium gallium selenide). Kodwa-ke, lezi zinto ngokuvamile zidinga amazinga okushisa aphezulu okucubungula, okuholela ekugxilweni kwekhabhoni ebalulekile.
Encwadini yabo yakamuva ku-Nature, u-Lang nozakwabo bahlanganisa ubuchwepheshe obubili obuthembisayo be-solar cell: i-perovskite namaseli elanga e-organic, angacutshungulwa emazingeni okushisa aphansi futhi abe nomthelela oncishisiwe we-carbon. Ukuzuza ukusebenza kahle okumangazayo okungama-25.7% ngale nhlanganisela entsha kwaba umsebenzi oyinselele, njengoba kuphawulwe uFelix Lang, owachaza, “Le mpumelelo yenziwe yaba khona kuphela ngokuhlanganisa intuthuko emibili ebalulekile.” Ukuphumelela kokuqala kwaba ukuhlanganiswa kweseli elisha lelanga elibomvu/elibomvu elimunca i-organic ka-Meng no-Li, elinweba amandla alo okumunca liye ebangeni le-infrared. U-Lang wachaza kabanzi, "Nokho, amaseli elanga e-tandem abhekane nemikhawulo ngenxa yongqimba lwe-perovskite, olulahlekelwa kakhulu ukusebenza kahle uma luklanyelwe ukumunca ngokuyinhloko izingxenye eziluhlaza okwesibhakabhaka neziluhlaza zokukhanya kwelanga.
