Muna Chivabvu 2022, CCTV yakashuma kuti data ichangoburwa kubva kuNational Energy Administration inoratidza kuti kubva ikozvino, mapurojekiti ekugadzira magetsi emagetsi ari kuvakwa ari 121 miriyoni kilowatts, uye zvinotarisirwa kuti gore negore photovoltaic simba rekugadzira richave richangobva kubatanidzwa kune grid. ne108 miriyoni kilowatts, kuwedzera kwe95.9% kupfuura gore rapfuura.
Kuenderera mberi kwekuwedzera kwepasi rose PV yakaiswa simba kwakawedzera kushandiswa kwelaser processing tekinoroji muindasitiri yephotovoltaic.Iko kuenderera mberi kwekuvandudza kwelaser processing tekinoroji kwakavandudzawo mashandisiro ekushandisa kwe photovoltaic simba.Zvinoenderana nehuwandu hunoenderana, iyo yepasi rose PV itsva yakaiswa yemusika musika yasvika 130GW muna 2020, ichityora nhoroondo nyowani yakakwirira.Nepo iyo yepasi rose PV yakaiswa simba yasvika pakakwirira patsva, senyika hombe yekugadzira-yakatenderedza, yeChina PV yakaiswa simba yakagara ichiramba ichikwira kumusoro.Kubva 2010, kubuda kwe photovoltaic masero muChina kwakapfuura 50% yehuwandu hwepasi rose, inova pfungwa chaiyo.Inopfuura hafu yepasi rose photovoltaic industry inogadzirwa uye inotengeswa kunze.
Sechishandiso cheindasitiri, laser ndiyo yakakosha tekinoroji muindasitiri yephotovoltaic.Laser inogona kuisa simba rakawanda munzvimbo diki yemuchinjikwa uye kuisunungura, ichivandudza zvakanyanya kushanda kwesimba rekushandisa, kuitira kuti ikwanise kucheka zvinhu zvakaoma.Kugadzirwa kwebhatiri kunonyanya kukosha mukugadzirwa kwe photovoltaic.Silicon masero anoita basa rinokosha mukugadzira simba re photovoltaic, ingave crystalline silicon masero kana matete firimu silicon masero.Mune crystalline silicon maseru, yakakwirira-kuchena imwe crystal / polycrystal inochekwa kuita silicon wafers emabhatiri, uye laser inoshandiswa kucheka zvirinani, chimiro, uye munyori, uyezve tambo maseru.
01 Bhatiri kumucheto passivation kurapwa
Chinhu chakakosha pakuvandudza kushanda kwemasero ezuva ndechekudzikisira kurasikirwa kwesimba kuburikidza nemagetsi ekuisa, kazhinji nekuisa uye kupfuudza mipendero yesilicon chips.Maitiro echinyakare anoshandisa plasma kurapa mupendero insulation, asi etching makemikari anoshandiswa anodhura uye anokuvadza nharaunda.Laser ine simba rakawanda uye simba rakakwirira rinogona kukurumidza kupfuudza kumucheto kwesero uye kudzivirira zvakanyanya kurasikirwa kwesimba.Nelaser yakaumbwa groove, kurasikirwa kwesimba kunokonzerwa nekudonha ikozvino kwesolar cell kunodzikiswa zvakanyanya, kubva pa10-15% yekurasikirwa kwakakonzerwa neyakajairwa kemikari etching process kusvika 2-3% yekurasikirwa kunokonzerwa nelaser tekinoroji. .
02 Ronga uye Kunyora
Kuronga silicon wafers nelaser yakajairika online maitiro e otomatiki akatevedzana welding ye solar maseru.Kubatanidza masero ezuva nenzira iyi kunoderedza mari yekuchengetedza uye kunoita kuti tambo dzebhatiri dzemodule imwe neimwe dzive dzakarongeka uye dzakasimba.
03 Kucheka uye kunyora
Parizvino, yakanyanya kumberi kushandisa laser kukwenya uye kucheka silicon wafers.Iyo ine yakakwirira kushandiswa kwechokwadi, yakakwirira kudzokorora kurongeka, kushanda kwakagadzikana, kukurumidza kukurumidza, kushanda kuri nyore uye kugadzirisa kuri nyore.
04 Silicon wafer marking
Iko kunoshamisa kushandiswa kwelaser musilicon photovoltaic indasitiri ndeyekumaka silicon pasina kukanganisa maitiro ayo.Wafer labeling inobatsira vagadziri vatevedzere yavo solar supply cheni uye ive nechokwadi chakagadzikana mhando.
05 Kubviswa kwemafirimu
Masero ezuva akaonda emufirimu anovimba nevapor deposition uye tekinoroji yekunyora kuti isarudze mamwe maseru kuti iwane magetsi ega.Imwe neimwe dhizaini yefirimu inoda kuiswa nekukurumidza pasina kukanganisa mamwe mativi eiyo substrate girazi nesilicon.Instantaneous ablation inotungamira kukuvadzwa kwedunhu pagirazi nesilicon layer, izvo zvinozotungamira mukutadza kwebhatiri.
Kuti ive nechokwadi chekugadzikana, kunaka uye kufanana kwekuita kwemagetsi ekugadzira pakati pezvikamu, iyo laser beam simba rinofanirwa kunyatsogadziriswa kune yekugadzira workshop.Kana iyo laser simba isingakwanise kusvika kune imwe nhanho, iyo scribing maitiro haigone kupedzwa.Saizvozvowo, danda rinofanira kuchengetedza simba mukati memutsetse wakamanikana uye chengetedza 7 * 24 maawa ekushanda mamiriro mumutsara wegungano.Zvese izvi zvinhu zvinoisa pamberi zvakaomesesa zvinodiwa zvelaser yakatarwa, uye yakaoma yekutarisa michina inofanirwa kushandiswa kuve nechokwadi chepamusoro pekushanda.
Vagadziri vanoshandisa kuyerwa kwesimba kuyera kugadzirisa iyo laser uye kuigadzirisa kuti isangane nezvinodiwa zvekushandisa.Kune epamusoro-simba lasers, kune akawanda akasiyana-siyana ekuyera maturusi emagetsi, uye epamusoro-simba ma detectors anogona kutyora muganho we lasers mumamiriro ezvinhu akakosha;MaLaser anoshandiswa mukucheka girazi kana mamwe maapplication ekuisa anoda kutariswa kune yakanaka hunhu hwedanda, kwete simba.
Kana iyo yakaonda firimu photovoltaic inoshandiswa kudzima zvinhu zvemagetsi, maitiro edanda akakosha kupfuura simba rekutanga.Saizi, chimiro uye simba zvinoita basa rakakosha mukudzivirira kuvuza ikozvino kwemodule bhatiri.Iyo laser beam iyo inobvisa iyo yakaiswa photovoltaic zvinhu pane yakakosha girazi ndiro inodawo kugadziriswa kwakanaka.Seyakanaka yekuonana nzvimbo yekugadzira bhatiri maseketi, danda rinofanira kuzadzisa zviyero zvese.Chete matanda emhando yepamusoro ane yakakwira kudzokororwa anogona kunyatso kudzima dunhu pasina kukuvadza girazi riri pazasi.Muchiitiko ichi, thermoelectric detector inokwanisa kuyera laser beam simba kakawanda inowanzodiwa.
Saizi yelaser beam centre ichakanganisa maitiro ayo ablation uye nzvimbo.Iyo kutenderera (kana ovality) yedanda ichakanganisa mutsara wevanyori wakamisikidzwa pane solar module.Kana iyo cribing isina kuenzana, iyo isingaenderane beam ellipticity inokonzeresa kukanganisa mune solar module.Chimiro chedanda rose chinokanganisawo kushanda kwesilicon doped chimiro.Kune vaongorori, zvakakosha kusarudza laser ine yakanaka mhando, zvisinei nekumhanyisa kumhanya uye mutengo.Nekudaro, pakugadzira, modhi yakakiyiwa lasers inowanzo shandiswa kune mapfupi mapurusi anodiwa evaporation mukugadzira bhatiri.
Zvishandiso zvitsva senge perovskite zvinopa yakachipa uye yakasiyana zvachose yekugadzira maitiro kubva echinyakare crystalline silicon mabhatiri.Imwe yemabhenefiti makuru eperovskite ndeyekuti inogona kuderedza kukanganiswa kwekugadzirisa uye kugadzira kwecrystalline silicon pane zvakatipoteredza uchichengetedza kushanda zvakanaka.Parizvino, iyo vapor deposition yezvinhu zvayo inoshandisawo laser processing tekinoroji.Naizvozvo, muindasitiri yephotovoltaic, laser tekinoroji iri kuwedzera kushandiswa mukuita doping.Photovoltaic lasers inoshandiswa mumhando dzakasiyana dzekugadzira.Mukugadzira crystalline silicon solar masero, laser tekinoroji inoshandiswa kucheka silicon machipisi uye edge insulation.Iyo doping yemupendero webhatiri ndeyekudzivirira pfupi dunhu remberi electrode uye kumashure electrode.Muchishandiso ichi, laser tekinoroji yakapfuura zvachose mamwe maitiro echinyakare.Zvinotendwa kuti kuchave nekuwanda kwekushandisa kwelaser tekinoroji mune yese photovoltaic inoenderana indasitiri mune ramangwana.
