Kev xaiv emitter (SE-Selectiveemiter) siv lead ua silicon hnub ci cell, uas yog, cov hlau rooj vag kab (electrode) raug tsis lees paub rau qhov sib cuag silicon, maj mam doped ntawm cov electrodes. Cov qauv zoo li no tuaj yeem txo qhov diffusion txheej sib xyaw, yog li txhim kho cov lus teb luv-yoj ntawm lub teeb, thaum txo qhov kev sib cuag ntawm lub hauv ntej hlau electrode thiab silicon, ua rau luv luv Circuit Court tam sim no, qhib hluav taws xob hluav taws xob, thiab cov khoom ua kom zoo dua, yog li txhim kho kev hloov pauv. Qhov kom zoo dua 1 ntawm cov qauv roj teeb txo cov kev ua haujlwm tsis zoo, txhim kho qhov muab tub lim 2, txo cov neeg nqa khoom Auger sib xyaw, txhim kho cov nyhuv passivation 3, txhim kho lub teeb luv yoj spectral teb, txhim kho luv luv tam sim no thiab qhib hluav taws xob hluav taws xob, luam ntawv phosphopers (Yunnan Normal University) Nta: Cov phosphite yog yooj yim xaiv.

Kuj tseem tuaj yeem ua tiav kev xaiv diffusion hauv ib lub sijhawm. Qhov thib ob, qhov corrosion ntawm diffusion npog txheej (Nanjing Middle Power) Nta: txheej txheej txheej yog silicon oxide lossis silicon nitride, etching slurry yog qhov tseem ceeb rau etch. Nws tseem muaj peev xwm tswj tau silicon oxide zaj duab xis tuab, tsim cov yeeb yaj kiab semi-blocking, pov tseg diffusion.

Nyuaj, slurry printing zog, diffusion uniformity, luam ntawv alignment. Thib peb, cov txheej txheem luam ntawv ncaj qha (Schmid, Centrotherm) Nta: Yuav tsum tau luam tawm cov yam ntxwv ntawm lub npog ntsej muag kom zoo, tiv thaiv hydrofluoric acid yog qhov zoo, tshem tawm yooj yim. Txheej txheem txheej txheem.

Nyuaj, diffusion yog uniform, luam ntawv yog raws nraim. Schmid&39;s Corrosion SE Battery Transfer Key Engineering, Centrothers Laser Eclipse Oxidation Film SE Battery Transfer. Plaub, ntub dej corrosion tsis kam txheej / plasma etching rejection yam ntxwv: ntub txoj kev yuav siv tau nyob rau hauv hydrofluoric acid thiab nitric acid system los yog muaj zog puag rau corrode exposed hnyav diffusion txheej rau hauv ntiav diffusion txheej.

Corrosion-resistant slurry. Plasma qhuav, fluoride ions tsim los ntawm fluoride los yog fluorinated fluoride los yog lwm yam fluoride, thiab lwm yam. Txoj kev qhuav kuj tuaj yeem npog nrog nyiaj muab tshuaj txhuam.

V. LDSE (New South Wales) Nta: Siv laser thiab electroplating, txheej txheem ntau dua, txheej txheem nyuaj. Electroplating muaj ntau yam kev xaiv.

Electroplating nyiaj conductivity yog kwv yees li 10 npaug ntawm cov nyiaj pulp. Muaj peev xwm txuag tau cov khoom muaj txiaj ntsig zoo. Siv npib tsib xee tooj liab nyiaj, los yog npib tsib xee-tooj ​​liab tin qauv, koj tuaj yeem txuag koj cov khoom muaj nqi.

Koj tuaj yeem ua nws nyias heev, lossis lwm yam kev ua haujlwm zoo. Rau, Silicon number case technology (Innovalingt, OTB) Nta: Tsuas yog ntxiv lub tshuab luam ntawv, koj tuaj yeem ua tiav qhov kev txhim kho loj dua. Yooj yim hloov kho raws li cov txheej txheem uas twb muaj lawm.
