Teknụzụ mkpuchi mkpuchi na Calcitonite Solar Cells

Na 2009, mgbe calcite mkpa-film mkpụrụ ndụ malitere ịpụta arụmọrụ ntụgharị bụ naanị 3.8%, ma mụbaa ngwa ngwa, Unit 2018, arụmọrụ ụlọ nyocha agafeela 23%. Usoro ihe omimi nke chalcogenide bụ ABX3, ọnọdụ A na-abụkarị ion metal, dị ka Cs + ma ọ bụ Rb +, ma ọ bụ otu na-arụ ọrụ organic. Dị ka (CH3NH3;), [CH (NH2)2]+; Ọnọdụ B na-abụkarị cations divalent, dị ka Pb2+ na Sn2+ ions; Ọnọdụ X na-abụkarị halogen anions, dị ka Br-, I-, Cl-. Site n'ịgbanwe akụkụ nke ogige ndị ahụ, bandwit a machibidoro iwu nke chalcogenide ogige bụ mgbanwe n'etiti 1.2 na 3.1 eV. Ntughari fotovoltaic dị elu nke mkpụrụ ndụ chalcogenide na obere ogologo wavelengths, dabere na sel nwere arụmọrụ ntụgharị pụtara ìhè na ogologo ogologo ogologo, dị ka mkpụrụ ndụ silicon crystalline dị iche iche, nwere ike nweta ngbanwe fotovoltaic nke ihe karịrị 30%, na-emebi site na njedebe nke sel sel kristal effiline. 2020, batrị a kpokọtara enwetalarị arụmọrụ ntụgharị nke 29.15% na ụlọ nyocha Berlin nke Heimholtz, Germany, na chalcogenide-crystalline silicon Stacked cell a na-ahụta dị ka otu n'ime teknụzụ batrị bụ isi nke ọgbọ na-abịa.

A na-enweta oyi akwa ihe nkiri chalcogenide site na usoro ụzọ abụọ: nke mbụ, porous Pbl2, na ihe nkiri CsBr na-edobere n'elu sel heterojunction na-egbuke egbuke site na ikpochapụ, wee kpuchie ya na ngwọta organohalide (FAI, FABr) site na mkpuchi mkpuchi. Ihe ngwọta organic halide na-abanye n'ime oghere nke ihe nkiri inorganic nke vepor na-echekwa ma meghachi omume na crystallizes na 150 degrees Celsius iji mepụta oyi akwa chalcogenide. Ọkpụrụkpụ nke ihe nkiri chalcogenide wee nweta ya bụ 400-500 nm, wee jikọta ya n'usoro ya na cell heterojunction dị n'okpuru iji kwalite mmakọ ugbu a. Ngwongwo njem eletrọn na ihe nkiri chalcogenide bụ LiF na C60, enwetara n'usoro site na ntinye ikuku ọkụ, na-esote ntinye atomic oyi akwa nke akwa mkpuchi, Sn02, na magnetron sputtering nke TCO dị ka oghere n'ihu electrode. Ntụkwasị obi nke cell a gbakọtara dị mma karịa nke chalcogenide otu oyi akwa cell, ma nkwụsi ike nke ihe nkiri chalcogenide n'okpuru mmetụta gburugburu ebe obibi nke mmiri vapor, ìhè, na okpomọkụ ka kwesịrị imeziwanye.
