2KW 3KW 4KW 5KW Hnub Ci Inverter

GI series 2KW 3KW 4KW 5KW hnub ci inverter

Thaum lub zog ntxiv rau cov silicon ntshiab (xws li nyob rau hauv daim ntawv ntawm tshav kub), nws ua rau ob peb lub electrons tawg tawm ntawm lawv cov ntaub ntawv covalent thiab tawm hauv lub atom. Txhua lub sij hawm ib qho hluav taws xob tawm, ib lub qhov tso tseg. Cov electrons ces yuav mus ncig ntawm lub lattice, nrhiav lwm lub qhov los nyob rau hauv. Cov hluav taws xob no hu ua cov neeg nqa khoom pub dawb, thiab lawv tuaj yeem nqa hluav taws xob tam sim no. Kev sib xyaw cov silicon ntshiab nrog phosphorus atoms tsuas yog siv lub zog me me kom dim ntawm qee qhov "ntau" electron ntawm phosphorus atom (lub sab nraud tsib electrons). Thaum doped nrog phosphorus atoms, qhov tshwm sim silicon Paub tias yog N-hom ("n" txhais tau tias tsis zoo them), tsuas yog ib feem ntawm lub hnub ci cell yog N-hom. Lwm qhov ntawm silicon yog doped nrog boron, thiab sab nraud electron plhaub ntawm boron tsuas muaj peb es tsis txhob ntawm plaub electrons, yog li ntawd P-hom silicon tuaj yeem tau. Tsis muaj cov electrons dawb hauv p-hom silicon.

Perovskite solar cells yog cov hnub ci hnub ci uas siv perovskite organic hlau halide semiconductors ua cov khoom siv teeb pom kev zoo, uas yog, cov dyes hauv dye-sensitized solar cells raug hloov raws li. Hauv cov qauv perovskite no (Daim duab 1), A feem ntau yog ib pawg methylamine, thiab kuj tau tshaj tawm; B feem ntau yog hlau Pb atom, thiab me me ntawm cov hlau Sn kuj tau tshaj tawm; X yog ib qho halogen tib atom xws li Cl, Br, thiab kuv, lossis sib xyaw atoms. Tam sim no nyob rau hauv high-efficiency perovskite hnub ci hlwb, cov khoom siv perovskite feem ntau yog lead iodide methylamine (PbI), uas muaj qhov sib txawv ntawm kwv yees li 1.5 eV.
