2022 igore rizere nematambudziko epasirese.Denda reNew Champions harisati rapera zvachose, uye dambudziko muRussia neUkraine ratevera.Mumamiriro ezvinhu aya akaoma uye asina kusimba epasirese, kudiwa kwesimba rekuchengetedza nyika dzese pasirese kuri kukura zuva nezuva.
Kuti utsungirire nekukura kwesimba gap mune ramangwana, iyo photovoltaic indasitiri yakakwezva kukura kunoputika.Panguva imwecheteyo, mabhizinesi akasiyana siyana arikushingairira kusimudzira chizvarwa chitsva chephotovoltaic cell tekinoroji kubata musika highland.
Tisati taongorora iyo iteration nzira ye cell tekinoroji, isu tinofanirwa kunzwisisa musimboti weiyo photovoltaic simba rekugadzira.
Photovoltaic simba rekugadzira tekinoroji inoshandisa iyo photovoltaic mhedzisiro ye semiconductor interface kushandura zvakananga simba rechiedza kuita simba remagetsi.Nheyo yayo huru ndeye photoelectric effect ye semiconductor: chiitiko chekugona kusiyana pakati peheterogeneous semiconductor kana zvikamu zvakasiyana zve semiconductor uye metal bonding inokonzerwa nechiedza.
Kana mafotoni achivheneka pasimbi, simba rinogona kutorwa neerekitironi musimbi, uye erekitironi inogona kupukunyuka kubva pamusoro pesimbi yova photoelectron.Maatomu eSilicon ane maerekitironi mana ekunze.Kana maatomu ephosphorous ane maerekitironi mashanu ekunze akadonhedzwa musilicon zvinhu, N-mhando silicon wafers anogona kuumbwa;Kana maatomu eboroni ane maerekitironi matatu ekunze akadonhedzwa musilicon zvinhu, P-mhando silicon chip inogona kuumbwa."
Iyo P mhando yebhatiri chip uye N mhando yebhatiri chip inogadzirirwa neP mhando silicon chip uye N mhando silicon chip kuburikidza neakasiyana matekinoroji.
Gore ra2015 risati rasvika, aluminium back field (BSF) bhatiri machipisi akatora musika wese.
Aluminium back field bhatiri ndiyo yakajairika bhatiri nzira: mushure mekugadzirwa kwePN junction yecrystalline silicon photovoltaic cell, dhizaini realuminium firimu rinoiswa pabacklight pamusoro pesilicon chip kugadzirira P + layer, nokudaro kugadzira aluminium kumashure kumunda. , kugadzira yakakwira uye yakaderera junction munda wemagetsi, uye kuvandudza yakavhurika yedunhu voltage.
Nekudaro, iyo irradiation resistance yealuminium back field bhatiri haina kunaka.Panguva imwecheteyo, muganhu wayo wekushandura unoshanda ndeye 20% chete, uye iyo chaiyo yekushandura yakaderera.Kunyangwe mumakore achangopfuura, indasitiri iyi yakavandudza maitiro eBSF bhatiri, asi nekuda kwekumisikidza kwayo, kuvandudzwa hakuna kukura, icho zvakare chikonzero nei ichifanirwa kutsiviwa.
Mushure me2015, chikamu chemusika chePerc bhatiri machipisi chakawedzera nekukurumidza.
Iyo Perc bhatiri chip inokwidziridzwa kubva kune yakajairwa aluminium back field bhatiri chip.Nekubatanidza dielectric passivation layer kuseri kwebhatiri, iyo photoelectric kurasikirwa inobudirira kuderedzwa uye iko kutendeuka kunoshanda kunovandudzwa.
Gore ra2015 raive gore rekutanga rekushandura tekinoroji yemasero ephotovoltaic.Mugore rino, kutengeserana kwePerc tekinoroji kwakapedzwa, uye kuwanda kwekugadzirwa kwemabhatiri kwakapfuura muganhu wekushandura mabhatiri ealuminium back field ne20% kekutanga, kupinda zviri pamutemo padanho rekugadzira ruzhinji.
Kubudirira kwekushandura kunomiririra zvikomborero zvepamusoro zvehupfumi.Mushure mekugadzirwa kwakawanda, chikamu chemusika chePerc bhatiri machipisi chakawedzera nekukurumidza uye chakapinda munhanho yekukura nekukurumidza.Mugove wemusika wakakwira kubva ku10.0% mu2016 kusvika 91.2% muna 2021. Parizvino, yakave iyo huru yebhatiri chip kugadzira tekinoroji mumusika.
Panyaya yekushanda zvakanaka kwekushandura, avhareji yekushandura kugadzirwa kwemabhatiri ePerc muna 2021 ichasvika 23.1%, 0.3% yakakwirira kupfuura iyo muna 2020.
Kubva pamaonero eiyo theoretical muganho kunyatsoita, zvinoenderana nekuverenga kweSolar Energy Research Institute, iyo theoretical muganho kunyatsoshanda kweP-mhando monocrystalline silicon Perc bhatiri i24.5%, iri padyo zvakanyanya neiyo theoretical muganho kushanda parizvino, uye pane zvishoma. nzvimbo yekuvandudza mune ramangwana.
Asi pari zvino, Perc ndiyo inonyanya kushandiswa bhatiri chip tekinoroji.Sekureva kweCPI, panosvika 2022, kugadzirwa kwakawanda kwemabhatiri ePERC kuchasvika 23.3%, huwandu hwekugadzira huchaverengera kupfuura 80%, uye chikamu chemusika chicharamba chiri chekutanga.
Iyo yazvino N-mhando bhatiri ine mabhenefiti ari pachena mukutendeuka kushanda zvakanaka uye ichave iyo huru yechizvarwa chinotevera.
Nheyo yekushanda yeN-mhando yebhatiri chip yakaunzwa kare.Hapana musiyano wakakosha pakati peiyo theoretical hwaro hwemhando mbiri dzebhatiri.Nekudaro, nekuda kwekusiyana kwehunyanzvi hwekuparadzira B uye P muzana ramakore, vanotarisana nematambudziko akasiyana uye tarisiro yebudiriro mukugadzirwa kwemaindasitiri.
Maitiro ekugadzirira erudzi rweP bhatiri ari nyore uye mutengo wakaderera, asi pane imwe gap pakati peP mhando bhatiri uye N mhando bhatiri maererano nekutendeuka kushanda zvakanaka.Maitiro erudzi rweN bhatiri akanyanya kuomarara, asi ane mabhenefiti epamusoro shanduko inoshanda, hapana mwenje attenuation, uye yakanaka isina simba mwenje mhedzisiro.
