Xyoo 2009, thaum cov hlwb nyias nyias calcite pib tshwm sim, qhov kev hloov pauv zoo tsuas yog 3.8%, thiab nce sai heev, Chav 2018, qhov kev ua haujlwm hauv chav kuaj tau tshaj 23%. Cov mis molecular yooj yim ntawm cov tshuaj chalcogenide yog ABX3, thiab qhov chaw A feem ntau yog cov hlau ion, xws li Cs+ lossis Rb+, lossis cov pab pawg ua haujlwm organic. Xws li (CH3NH3;), [CH (NH2)2]+; Qhov chaw B feem ntau yog cov cations divalent, xws li Pb2+ thiab Sn2+ ions; Qhov chaw X feem ntau yog halogen anions, xws li Br-, I-, Cl-. Los ntawm kev hloov cov khoom ntawm cov tshuaj, qhov bandwidth txwv tsis pub ntawm cov tshuaj chalcogenide tuaj yeem hloov kho tau ntawm 1.2 thiab 3.1 eV. Kev hloov pauv photovoltaic ua haujlwm siab ntawm cov hlwb chalcogenide ntawm cov nthwv dej luv luv, uas tau muab tso rau ntawm cov hlwb uas muaj kev ua tau zoo hloov pauv ntawm cov nthwv dej ntev, xws li cov hlwb crystalline silicon heterogeneous, tuaj yeem tau txais kev hloov pauv photovoltaic ntau dua 30%, hla dhau qhov txwv ntawm kev hloov pauv theoretical ntawm cov hlwb crystalline silicon ntawm 29.4%. Xyoo 2020, lub roj teeb stacked no twb tau ua tiav kev hloov pauv ntawm 29.15% hauv Berlin Laboratory ntawm Heimholtz, Lub Tebchaws Yelemees, thiab chalcogenide-crystalline silicon Stacked cell raug suav hais tias yog ib qho ntawm cov thev naus laus zis roj teeb tseem ceeb ntawm tiam tom ntej.
Cov txheej txheem zaj duab xis chalcogenide tau ua tiav los ntawm ob kauj ruam: thawj zaug, cov zaj duab xis Pbl2 porous, thiab CsBr tau tso rau ntawm qhov chaw ntawm cov hlwb heterojunction nrog cov nplaim fluffy los ntawm kev sib koom ua ke, thiab tom qab ntawd npog nrog cov kua organohalide (FAI, FABr) los ntawm kev sib xyaw ua ke. Cov kua organic halide nkag mus rau hauv cov qhov hws ntawm cov zaj duab xis inorganic uas tau tso pa tawm thiab tom qab ntawd ua rau thiab crystallizes ntawm 150 degrees Celsius los tsim cov txheej txheem zaj duab xis chalcogenide. Qhov tuab ntawm cov zaj duab xis chalcogenide yog li tau txais yog 400-500 nm, thiab nws tau txuas nrog cov hlwb heterojunction hauv qab kom ua kom zoo dua qhov sib phim tam sim no. Cov txheej txheem thauj hluav taws xob ntawm cov zaj duab xis chalcogenide yog LiF thiab C60, tau txais los ntawm kev tso pa thermal, ua raws li cov txheej txheem atomic ntawm cov txheej txheem buffer, Sn02, thiab magnetron sputtering ntawm TCO ua lub electrode pem hauv ntej pob tshab. Qhov kev ntseeg tau ntawm lub cell uas muab sib dhos ua ke no zoo dua li ntawm lub cell ib txheej chalcogenide, tab sis qhov kev ruaj khov ntawm zaj duab xis chalcogenide nyob rau hauv cov kev cuam tshuam ntawm cov dej ua pa, lub teeb, thiab cua sov tseem yuav tsum tau txhim kho.
