Kugwiritsa ntchito Laser pakupanga ma solar batter Production

Mu May 2022, CCTV inanena kuti zaposachedwa kwambiri kuchokera ku National Energy Administration zikuwonetsa kuti kuyambira pano, mapulojekiti opanga magetsi a photovoltaic omwe akumangidwa ndi ma kilowatts miliyoni 121, ndipo akuyembekezeka kuti mphamvu yamagetsi yapachaka ya photovoltaic ingolumikizidwa kumene ndi grid. ndi 108 miliyoni kilowatts, chiwonjezeko cha 95.9% kuposa chaka chatha.

Kuwonjezeka kosalekeza kwa mphamvu ya PV yapadziko lonse lapansi kwathandizira kugwiritsa ntchito luso la laser processing makampani opanga photovoltaic.Kuwongolera kosalekeza kwaukadaulo wa laser processing kwathandiziranso kugwiritsa ntchito mphamvu ya photovoltaic.Malinga ndi ziwerengero zoyenera, msika wapadziko lonse wa PV watsopano woyikirapo wafika pa 130GW mu 2020, ndikuphwanya mbiri yatsopano.Pomwe mphamvu yoyika PV yapadziko lonse lapansi yafika pachimake chatsopano, ngati dziko lalikulu lopanga zinthu zonse, mphamvu yaku China yoyika PV yakhala ikukwera.Kuyambira 2010, kutulutsa kwa ma cell a photovoltaic ku China kwadutsa 50% ya kuchuluka kwapadziko lonse lapansi, zomwe ndi lingaliro lenileni.Zoposa theka la mafakitale a photovoltaic padziko lonse lapansi amapangidwa ndikutumizidwa kunja.

Monga chida cha mafakitale, laser ndiukadaulo wofunikira mumakampani a photovoltaic.Laser imatha kuyika mphamvu zambiri pamalo ang'onoang'ono a mtanda ndikuwumasula, kuwongolera kwambiri mphamvu yogwiritsira ntchito mphamvu, kuti athe kudula zida zolimba.Kupanga batri ndikofunikira kwambiri pakupanga kwa photovoltaic.Maselo a silicon amagwira ntchito yofunika kwambiri pakupanga mphamvu ya photovoltaic, kaya ndi maselo a crystalline silicon kapena maselo owonda kwambiri a silicon.M'maselo a crystalline silicon, high-purity single crystal / polycrystal imadulidwa muzitsulo za silicon pamabatire, ndipo laser imagwiritsidwa ntchito podula bwino, mawonekedwe, ndi kulemba, ndiyeno amangirira maselo.

01 Battery m'mphepete passivation chithandizo

Chofunikira kwambiri pakuwongolera magwiridwe antchito a ma cell a solar ndikuchepetsa kutayika kwa mphamvu kudzera pakutchinjiriza kwamagetsi, nthawi zambiri pomangirira ndi kudutsa m'mphepete mwa tchipisi ta silicon.Njira yachikhalidwe imagwiritsa ntchito madzi a m'magazi kuti azitha kutchinjiriza m'mphepete, koma mankhwala omwe amagwiritsidwa ntchito ndi okwera mtengo komanso owononga chilengedwe.Laser yokhala ndi mphamvu zambiri komanso mphamvu yayikulu imatha kudutsa m'mphepete mwa selo ndikuletsa kutaya mphamvu kwambiri.Ndi laser yopangidwa ndi groove, kutayika kwa mphamvu komwe kumachitika chifukwa cha kutayikira kwa cell ya solar kumachepetsedwa kwambiri, kuchokera ku 10-15% ya kutayika komwe kumachitika chifukwa cha njira yachikhalidwe yopangira mankhwala mpaka 2-3% ya kutayika komwe kumachitika chifukwa chaukadaulo wa laser. .

02 Konzani ndi Kulemba

Kukonza zowotcherera za silicon ndi laser ndi njira wamba yapaintaneti yowotcherera ma cell a solar.Kugwirizanitsa maselo a dzuwa motere kumachepetsa mtengo wosungirako ndipo kumapangitsa kuti zingwe za batri za module iliyonse zikhale zadongosolo komanso zowonjezereka.

03 Kudula ndi kulemba

Pakadali pano, ndizotsogola kwambiri kugwiritsa ntchito laser kukanda ndikudula zowotcha za silicon.Ili ndi kulondola kwakukulu kogwiritsa ntchito, kubwereza kubwerezabwereza, kugwira ntchito kosasunthika, kuthamanga kwachangu, ntchito yosavuta komanso kukonza bwino.

04 Chizindikiro cha siliconndi

Kugwiritsa ntchito modabwitsa kwa laser mumakampani a silicon photovoltaic ndikuyika chizindikiro cha silicon popanda kukhudza mayendedwe ake.Kulemba zilembo za Wafer kumathandiza opanga kutsata mayendedwe awo a solar ndikuwonetsetsa kuti zinthu zili bwino.

05 Kutulutsidwa kwa mafilimu

Maselo owoneka bwino a solar amadalira ukadaulo wa nthunzi ndi ukadaulo wolembera kuti achepetse zigawo zina kuti akwaniritse kudzipatula kwamagetsi.Gawo lirilonse la filimuyo liyenera kuikidwa mofulumira popanda kukhudza zigawo zina za galasi la gawo lapansi ndi silicon.Kutulutsa nthawi yomweyo kumabweretsa kuwonongeka kwa dera pamagalasi ndi silicon, zomwe zingayambitse kulephera kwa batri.

Pofuna kuonetsetsa kuti kukhazikika, khalidwe ndi kufanana kwa mphamvu zopangira mphamvu pakati pa zigawo zikuluzikulu, mphamvu ya laser laser iyenera kusinthidwa mosamala pa msonkhano wopanga.Ngati mphamvu ya laser sichitha kufika pamlingo wina, kulemba sikungatheke.Mofananamo, mtengowo uyenera kusunga mphamvu mkati mwa njira yopapatiza ndikuwonetsetsa kuti 7 * 24 maola ogwira ntchito pamzere wa msonkhano.Zinthu zonsezi zimayika patsogolo zofunikira kwambiri pamafotokozedwe a laser, ndipo zida zowunikira zovuta ziyenera kugwiritsidwa ntchito kuwonetsetsa kuti zikuyenda bwino.

Opanga amagwiritsa ntchito kuyeza kwamphamvu kwa mtengo kuti asinthe makina a laser ndikuwongolera kuti akwaniritse zofunikira.Kwa ma lasers amphamvu kwambiri, pali zida zambiri zoyezera mphamvu zosiyanasiyana, ndipo zowunikira zamphamvu zimatha kuswa malire a ma laser pamikhalidwe yapadera;Ma laser omwe amagwiritsidwa ntchito podula magalasi kapena ntchito zina zoyikapo amafunikira chidwi ndi mawonekedwe abwino a mtengo, osati mphamvu.

Pamene filimu yopyapyala ya photovoltaic imagwiritsidwa ntchito kuwononga zipangizo zamagetsi, zizindikiro za mtengo ndizofunika kwambiri kuposa mphamvu zoyambirira.Kukula, mawonekedwe ndi mphamvu zimagwira ntchito yofunika kwambiri poletsa kutayikira kwa batire ya module.Mtengo wa laser womwe umayatsa zinthu zoyikidwa pagalasi pagalasi umafunikanso kusintha bwino.Monga malo abwino olumikizirana popanga mabwalo a batri, mtengowo uyenera kukwaniritsa miyezo yonse.Ma matabwa apamwamba okha omwe ali ndi kubwereza kwambiri amatha kuwongolera dera popanda kuwononga galasi lomwe lili pansipa.Pankhaniyi, chowunikira cha thermoelectric chomwe chimatha kuyeza mphamvu ya laser mobwerezabwereza chimafunika.

Kukula kwa malo a laser beam kumakhudza momwe amachitira komanso malo ake.Kuzungulira (kapena ovality) kwa mtengowo kudzakhudza mzere wa mlembi womwe ukuwonetsedwa pa module ya dzuwa.Ngati kulembera sikuli kofanana, kusagwirizana kwa ellipticity kumayambitsa zolakwika mu module ya solar.Maonekedwe a mtengo wonse amakhudzanso mphamvu ya kapangidwe ka silicon doped.Kwa ofufuza, ndikofunikira kusankha laser yokhala ndi khalidwe labwino, mosasamala kanthu za liwiro la kukonza ndi mtengo.Komabe, popanga, ma laser otsekeka amachitidwe nthawi zambiri amagwiritsidwa ntchito ngati ma pulse afupiafupi omwe amafunikira kuti atuluke popanga batire.

Zida zatsopano monga perovskite zimapereka njira yotsika mtengo komanso yosiyana kwambiri ndi mabatire a crystalline silicon.Ubwino umodzi waukulu wa perovskite ndikuti ukhoza kuchepetsa kukhudzidwa kwa kukonza ndi kupanga silicon ya crystalline pa chilengedwe ndikusunga bwino.Pakali pano, nthunzi mafunsidwe zipangizo zake amagwiritsanso laser processing luso.Chifukwa chake, mumakampani a photovoltaic, ukadaulo wa laser umagwiritsidwa ntchito kwambiri popanga doping.Ma laser a Photovoltaic amagwiritsidwa ntchito munjira zosiyanasiyana zopanga.Popanga ma crystalline silicon solar cell, ukadaulo wa laser umagwiritsidwa ntchito podula tchipisi ta silicon ndi kutchinjiriza m'mphepete.Doping ya m'mphepete mwa batire ndikuletsa kufupi kwa ma elekitirodi akutsogolo ndi ma elekitirodi akumbuyo.Pogwiritsa ntchito izi, ukadaulo wa laser waposa njira zina zachikhalidwe.Zimakhulupirira kuti padzakhala zowonjezereka zogwiritsira ntchito teknoloji ya laser mu makampani onse okhudzana ndi photovoltaic m'tsogolomu.
