Kwiminyaka yakutshanje, ishishini le-photovoltaic laseTshayina lisebenzise ngokupheleleyo isiseko salo sobuchwepheshe kunye nezibonelelo ezixhasayo kwimizi-mveliso ukuphuhlisa ngokukhawuleza, ngokuthe ngcembe ukufumana iingenelo zokhuphiswano lwamazwe ngamazwe kunye nokuhlanganisa ngokuqhubekayo, kwaye sele bephethe ikhonkco loshishino olupheleleyo lwe-photovoltaic emhlabeni.
Kwikhonkco loshishino lwe-photovoltaic, izixhobo eziluhlaza ezinyukayo zibandakanya ii-silicon wafers, i-slurry yesilivere, uthuthu lwesoda, isanti yequartz, njl.I-midstream ihlukaniswe yaba ngamacandelo amabini amakhulu, iipaneli ze-photovoltaic kunye neemodyuli ze-photovoltaic;I-Downstream yintsimi yesicelo se-photovoltaic, esetyenziselwa ukuveliswa kwamandla kwaye inokubuyisela i-fuel yokufudumeza kunye nezinye iinjongo.
1. Umthamo ofakiweyo wokuvelisa amandla e-photovoltaic ukhula ngokuthe ngcembe
Umthamo ofakiweyo wokuvelisa amandla e-photovoltaic ubhekisela kwisixa esipheleleyo sokuvelisa amandla e-photovoltaic.Ngokutsho kwedatha, amandla afakiweyo okuvelisa amandla e-photovoltaic e-China afikelele kwi-253.43 GW kwi-2020, kunye ne-267.61 GW kwisiqingatha sokuqala se-2021, ukunyuka konyaka-ngonyaka we-23.7%.
2. Ukunyuka kwemveliso ye-silicon ye-polycrystalline
Ngokwe-polycrystalline silicon, ngo-2020, imveliso yesizwe ye-polycrystalline silicon ifikelele kwiitoni ze-392000, ukunyuka konyaka-ngonyaka we-14.6%.Phakathi kwabo, amashishini amahlanu aphezulu enza i-87.5% yemveliso yepolysilicon yasekhaya iyonke, kunye namashishini amane avelisa ngaphezulu kweetoni ezingama-50000.Kwisiqingatha sokuqala sonyaka, imveliso yesizwe ye-polycrystalline silicon ifikelele kwiitoni ze-238000, ukunyuka konyaka-ngonyaka kwe-16.1%.
3. Ukuveliswa kweeseli ze-photovoltaic ziyaqhubeka zikhula
Iiseli ze-photovoltaic zisetyenziselwa ukuguqula ngokuthe ngqo amandla okukhanya kwelanga kumandla ombane.Ngokohlobo lwemathiriyeli yebhetri, zinokwahlulwa ngokulinganayo kwiiseli ze-silicon zekristale kunye neeseli zelanga zefilimu.Kwiminyaka yakutshanje, ukuveliswa kweeseli ze-photovoltaic e-China kuye kwaqhubeka nokukhula.Kwisiqingatha sokuqala se-2021, imveliso ye-photovoltaic cell yaseChina yafikelela kwi-97.464 yezigidi ze-kilowatts, ukunyuka konyaka-ngonyaka kwe-52.6%.
4. Ukukhula okukhawulezileyo kwemveliso yemodyuli ye-photovoltaic
Iimodyuli ze-Photovoltaic yiyunithi encinci esebenzayo yokuvelisa amandla.Iimodyuli ze-Photovoltaic ikakhulu ziquka amacandelo angundoqo alithoba, kubandakanywa iiseli zebhetri, imivalo yokudibanisa, iibhasi, iglasi epholileyo, i-EVA, i-backplanes, i-aluminium alloys, i-silicone, kunye neebhokisi ze-junction.Ngo-2020, imveliso yemodyuli ye-photovoltaic yaseChina yayiyi-125GW, kwaye kwisiqingatha sokuqala se-2021, imveliso yemodyuli ye-photovoltaic yayingu-80.2GW, ukunyuka konyaka-ngonyaka we-50.5%.
