Gukoresha Laser muri batteri yizuba Gukora

Muri Gicurasi 2022, CCTV yatangaje ko amakuru aheruka gutangwa n’ikigo cy’igihugu gishinzwe ingufu agaragaza ko kugeza ubu, imishinga y’amashanyarazi y’amashanyarazi irimo kubakwa ari miliyoni 121 kilowat, kandi bikaba biteganijwe ko amashanyarazi y’amashanyarazi ya buri mwaka azahuzwa na gride. na miliyoni 108 kilowatts, yiyongereyeho 95.9% mu mwaka ushize.

Kwiyongera kwubushobozi bwa PV kwisi kwashyizweho byihutishije ikoreshwa rya tekinoroji yo gutunganya laser mu nganda zifotora.Gukomeza kunoza tekinoroji yo gutunganya laser byanatezimbere ikoreshwa ryingufu za Photovoltaque.Dukurikije imibare ifatika, isoko mpuzamahanga yubushobozi bwa PV yashyizwe ku isi igera kuri 130GW muri 2020, isenya amateka mashya.Mu gihe ubushobozi bwa PV bwashyizweho ku isi bugeze ku rwego rwo hejuru, nk’igihugu kinini cy’ibicuruzwa byose, Ubushinwa bwa PV bwashyizeho uburyo bwo kuzamuka.Kuva mu mwaka wa 2010, umusaruro w'ingirabuzimafatizo zifotora mu Bushinwa warenze 50% by'umusaruro rusange ku isi, ibyo bikaba byumvikana.Kurenga kimwe cya kabiri cyinganda zifotora kwisi zirakorwa kandi zoherezwa hanze.

Nibikoresho byinganda, laser nubuhanga bwingenzi mu nganda zifotora.Laser irashobora kwegeranya ingufu nyinshi mukarere gato kambukiranya hanyuma ikayirekura, igatezimbere cyane imikorere yo gukoresha ingufu, kuburyo ishobora guca ibikoresho bikomeye.Gukora bateri nibyingenzi mubikorwa byo gufotora.Utugingo ngengabuzima twa Silicon tugira uruhare runini mu kubyara ingufu za Photovoltaque, yaba selile silicon silicon cyangwa selile silicon selile.Muri sisitemu ya kirisiti ya kirisiti, isukuye cyane ya kirisiti / polycristal yaciwe muri wafer ya silicon ya bateri, kandi laser ikoreshwa mugukata neza, gushushanya, no kwandika, hanyuma ugakurikirana ingirabuzimafatizo.

01 Umuti wa batiri wo kuvura

Ikintu cyingenzi cyogutezimbere imikorere yizuba ni ukugabanya gutakaza ingufu binyuze mumashanyarazi, mubisanzwe mugukata no gutambutsa impande za chipiki.Inzira gakondo ikoresha plasma kugirango ivure inkombe, ariko imiti ikoreshwa ikoreshwa ihenze kandi yangiza ibidukikije.Lazeri ifite ingufu nyinshi nimbaraga nyinshi zirashobora kwihuta kunyura kumpera ya selile no kwirinda gutakaza ingufu nyinshi.Hamwe na lazeri yashizweho na groove, gutakaza ingufu ziterwa numuyoboro wizuba uturuka kumirasire yizuba biragabanuka cyane, kuva 10-15% byigihombo cyatewe nuburyo gakondo bwo guterwa imiti bugera kuri 2-3% byigihombo cyatewe nikoranabuhanga rya laser. .

02 Tegura kandi Wandike

Gutegura wafer ya silicon na laser nuburyo busanzwe bwo kumurongo wo gusudira byikora byizuba byizuba.Guhuza imirasire y'izuba murubu buryo bigabanya ikiguzi cyo kubika kandi bigatuma imirongo ya batiri ya buri module iringaniye kandi yoroheje.

03 Gukata no kwandika

Kugeza ubu, birateye imbere gukoresha laser mugushushanya no guca wafer ya silicon.Ifite imikoreshereze ihanitse, isubiramo ryukuri, imikorere ihamye, umuvuduko wihuse, imikorere yoroshye no kuyitaho neza.

04 Ikimenyetso cya wafering

Ikoreshwa ridasanzwe rya laser mu nganda za silicon Photovoltaic ni ukuranga silikoni itagize ingaruka ku mikorere yayo.Ibirango bya Wafer bifasha ababikora gukurikirana urumuri rwizuba kandi bakemeza neza.

05 Gukuraho firime

Imirasire y'izuba ntoya yishingikiriza kumyuka yumuyaga hamwe nubuhanga bwo kwandika kugirango uhitemo ibice bimwe kugirango ugere kumashanyarazi.Buri cyiciro cya firime kigomba kubikwa vuba bitagize ingaruka kubindi bice byikirahuri cya substrate na silicon.Kwiyuhagira ako kanya bizatera kwangirika kwizuba kumirahuri na silikoni, bizatera gutsindwa kwa batiri.

Kugirango habeho ituze, ubuziranenge nuburinganire bwimikorere yamashanyarazi hagati yibigize, ingufu za laser beam zigomba guhindurwa neza mumahugurwa yo gukora.Niba imbaraga za laser zidashobora kugera kurwego runaka, inzira yo kwandika ntishobora kurangira.Mu buryo nk'ubwo, urumuri rugomba kugumana imbaraga mu ntera ntoya kandi ikemeza ko amasaha 7 * 24 akora mumurongo winteko.Izi ngingo zose zashyize ahagaragara ibisabwa cyane kubisobanuro bya laser, kandi ibikoresho bigoye byo kugenzura bigomba gukoreshwa kugirango imikorere yimikorere.

Ababikora bakoresha ibipimo byamashanyarazi kugirango bahindure lazeri kandi bayihindure kugirango babone ibisabwa.Kubikoresho byimbaraga nyinshi, hariho ibikoresho byinshi bitandukanye byo gupima ingufu, kandi ibyuma bisohora imbaraga birashobora guca imipaka ya laseri mubihe bidasanzwe;Lazeri ikoreshwa mugukata ibirahuri cyangwa ubundi buryo bwo kubika bisaba kwitondera ibintu byiza biranga urumuri, ntabwo ari imbaraga.

Iyo firime yoroheje ifotora ikoreshwa mugukuraho ibikoresho bya elegitoronike, ibiranga urumuri ni ngombwa kuruta imbaraga zumwimerere.Ingano, imiterere n'imbaraga bigira uruhare runini mukurinda kumeneka ya bateri ya module.Urumuri rwa lazeri rusibanganya ibikoresho byabitswe bifotora kuri plaque yibanze nayo ikenera guhinduka neza.Nka ngingo nziza yo guhuza imiyoboro ya batiri, urumuri rugomba kuba rwujuje ubuziranenge.Gusa ibiti byo murwego rwohejuru hamwe nibisubirwamo byinshi birashobora gukuraho neza uruziga bitangiza ikirahuri hepfo.Muri iki gihe, icyuma gipima ubushyuhe gishobora gupima ingufu za laser beam inshuro nyinshi birasabwa.

Ingano yikigo cya laser kizagira ingaruka kuburyo bwo gukuraho no kuba.Ubuzenguruko (cyangwa ovality) bw'igiti bizagira ingaruka ku murongo w'abanditsi uteganijwe ku zuba.Niba imyandikire idahwanye, elliptike ya beam idahuye bizatera inenge mumirasire y'izuba.Imiterere yibiti byose nayo igira ingaruka kumikorere ya silicon yubatswe.Kubashakashatsi, ni ngombwa guhitamo laser ifite ireme ryiza, utitaye kumuvuduko wo gutunganya nigiciro.Nyamara, kubyara umusaruro, uburyo bwo gufunga lazeri bukoreshwa mubisanzwe bigufi bikenerwa no guhumeka mugukora bateri.

Ibikoresho bishya nka perovskite bitanga uburyo buhendutse kandi butandukanye rwose bwo gukora kuva muri bateri gakondo ya kristaline.Imwe mu nyungu zikomeye za perovskite nuko ishobora kugabanya ingaruka zo gutunganya no gukora silikoni ya kirisiti ku bidukikije mugihe ikomeza gukora neza.Kugeza ubu, imyuka yibikoresho byayo nayo ikoresha tekinoroji yo gutunganya laser.Kubwibyo, mu nganda zifotora, tekinoroji ya laser ikoreshwa cyane mugikorwa cya doping.Lazeri ya Photovoltaque ikoreshwa muburyo butandukanye bwo gukora.Mu gukora ingirabuzimafatizo zikomoka ku mirasire y'izuba ya kirisiti, tekinoroji ya laser ikoreshwa mu guca chipiki ya silicon hamwe no gukingira inkombe.Doping yumupaka wa batiri nugukumira inzitizi ngufi ya electrode yimbere na electrode yinyuma.Muri iyi porogaramu, tekinoroji ya laser yarenze rwose izindi nzira gakondo.Byizerwa ko hazabaho byinshi kandi byinshi byikoranabuhanga rya laser mu nganda zose zijyanye na fotovoltaque.
