Teknụzụ mkpuchi na mkpụrụ ndụ anyanwụ Calcitonite

Na 2009, mgbe mkpụrụ ndụ ihe nkiri calcite malitere ịpụta na ntụgharị ahụ bụ naanị 3.8%, ma mụbaa ngwa ngwa, Unit 2018, arụmọrụ ụlọ nyocha agafeela 23%. Usoro molekul bụ isi nke ihe mejupụtara chalcogenide bụ ABX3, ọnọdụ A na-abụkarị ion ígwè, dị ka Cs+ ma ọ bụ Rb+, ma ọ bụ otu ọrụ organic. Dịka (CH3NH3;), [CH (NH2)2]+; Ọnọdụ B na-abụkarị cations divalent, dị ka ions Pb2+ na Sn2+; ọnọdụ X na-abụkarị halogen anions, dị ka Br-, I-, Cl-. Site na ịgbanwe ihe ndị mejupụtara ihe mejupụtara, a na-agbanwe bandwidth amachibidoro nke ihe mejupụtara chalcogenide n'etiti 1.2 na 3.1 eV. Mgbanwe fotovoltaic dị elu nke mkpụrụ ndụ chalcogenide na ogologo ebili mmiri dị mkpụmkpụ, nke a na-etinye n'ime mkpụrụ ndụ nwere arụmọrụ mgbanwe dị egwu na ogologo ebili mmiri dị ogologo, dị ka mkpụrụ ndụ silicon kristal dị iche iche, nwere ike nweta arụmọrụ mgbanwe fotovoltaic nke karịrị 30%, na-agafe oke arụmọrụ mgbanwe echiche nke mkpụrụ ndụ silicon kristal nke 29.4%. 2020, batrị a gbakọtara agwakọta enwetalarị arụmọrụ mgbanwe nke 29.15% na Berlin Laboratory nke Heimholtz, Germany, a na-ewerekwa chalcogenide-crystalline silicon stacked cell dị ka otu n'ime teknụzụ batrị kachasị mkpa nke ọgbọ na-abịa.

E ji usoro nzọụkwụ abụọ chọpụta oyi akwa ihe nkiri chalcogenide: nke mbụ, a na-etinye ihe nkiri Pbl2 na CsBr dị larịị n'elu mkpụrụ ndụ heterojunction nwere elu dị nro site na co-evaporation, wee kpuchie ya na ngwọta organohalide (FAI, FABr) site na mkpuchi spin-coating. Ngwọta halide organic na-abanye n'ime oghere nke ihe nkiri inorganic nke vapor-deposited wee meghachi omume ma na-agbanwe na ogo Celsius 150 iji mepụta oyi akwa ihe nkiri chalcogenide. Ọkpụrụkpụ nke ihe nkiri chalcogenide e si otú a nweta bụ 400-500 nm, e jikọtara ya na sel heterojunction dị n'okpuru iji mee ka ndakọrịta ugbu a dịkwuo mma. Ibe mbufe elektrọn na ihe nkiri chalcogenide bụ LiF na C60, nke a na-enweta n'usoro site na nkwụnye okpomọkụ vapor, nke a na-esote ntinye akwa atomic nke oyi akwa buffer, Sn02, na ntinye magnetron nke TCO dị ka elektrọd ihu doro anya. Ntụkwasị obi nke mkpụrụ ndụ a gbakọtara agwakọta ka mma karịa nke mkpụrụ ndụ chalcogenide nke nwere otu oyi akwa, mana ọ ka dị mkpa ka eme ka nkwụsi ike nke ihe nkiri chalcogenide dị mma n'okpuru mmetụta gburugburu ebe obibi nke uzuoku mmiri, ìhè, na okpomọkụ.
