Iseli yelanga ye-silicon ekristale ngokwayo ayinamandla oomatshini kwaye idla ngokuqhekeka. Ukufuma kunye neegesi ezirhabaxa emoyeni ziya kunyibilikisa i-electrode kancinci kancinci, engakwaziyo ukumelana neemeko ezinzima zokusebenza emoyeni ovulekileyo. Ngenxa yesi sizathu, iiseli zelanga zihlala zipakishwa ngeglasi ye-photovoltaic nge-EVA kunye nephaneli yangasemva. Iglasi ye-Photovoltaic kwiimodyuli ze-photovoltaic ukukhusela ibhetri emanzini nakwigesi, ithintele i-oksijini ukuthintela i-oxidation, ukumelana nobushushu obuphezulu nobuphantsi, ukugquma okuhle kunye nokumelana nokuguga. Iglasi ye-Photovoltaic luhlobo lweglasi ye-silicate enomxholo wesinyithi ophantsi, okwaziwa ngokuba yiglasi emhlophe kakhulu.
Iglasi ye-photovoltaic esetyenziswa kwiseli ye-crystal silicon yahlukile kwiglasi edadayo. Umphezulu ophezulu weglasi ye-photovoltaic yi-suede, nto leyo eyenza kube nzima ukuba ukukhanya kungene ngqo kumphezulu wemodyuli ukuvelisa ukubonakaliswa kwe-specular. Umphezulu ongezantsi ugqunywe nge-embossed, nto leyo enokuphucula amandla okuncamathelisa ngefilimu ye-EVA.
Izinto eziphambili zeglasi ye-photovoltaic
Izinto eziphambili zeglasi ye-photovoltaic ziquka isanti ye-quartz, i-soda ash, i-limestone, i-dolomite, i-sodium nitrate, ityuwa ye-glauber, i-sodium pyroantimonate, i-aluminium hydroxide, njl. Isanti ye-quartz idlala indima yomzimba wokwakheka kwenethiwekhi, idosi idla ngokuthatha uninzi lwecandelo leglasi, i-soda ash isetyenziselwa ikakhulu ukubonelela nge-sodium oxide, ikakhulu ukunciphisa ubushushu bokunyibilika kweglasi; Indima ephambili ye-limestone kukulungelelanisa i-viscosity yeglasi ukuya kwixabiso elifanelekileyo, ukuze ixesha lokubumba iglasi lihlangabezane neemfuno zokubumba, ityuwa ye-glauber isetyenziswa kakhulu njenge-clarifier, esetyenziselwa ukususa amaqamza kwiglasi, ukubonelela ngokudluliselwa kweglasi.
Umlinganiselo wokusetyenziswa kwezinto ezikrwada zeglasi ye-Photovoltaic
Iglasi ye-Photovoltaic idla ngokulungiswa ngendlela yokulungisa i-calendar, kwaye inkqubo yemveliso inokwahlulwa ibe ngamanqanaba amabini: ukuveliswa kwamaphepha kunye nokucubungula nzulu. Imveliso yokuqala ibandakanya ikakhulu ukuxutywa, ukunyibilika, ukulinganisa, ukuncibilikisa kunye nokusika. Malunga ne-1100 ℃ kwinkqubo yokuqengqeleka, iglasi enyibilikisiweyo, iirola zekhalenda ziqengqeleka kwaye zipholile, ngesantya esithile zifikelela kubukhulu obuthile, ububanzi obuthile, ipateni ethile, ngeglasi yesantya se-91.5%, emva koko emva kokufaka i-alnealing, yenza iglasi ibe ne-curve yoxinzelelo ezinzileyo, ukuba namandla athile, akulula ukuwaphula, akulungele ukusika, ukucubungula iglasi. Kubalulekile ukukhankanya ukuba kukho umahluko phakathi komgca wemveliso weglasi egqunywe yi-photovoltaic kunye neglasi edadayo.
Inkqubo yokucubungula ngokunzulu idla ngokuba yiglasi yokuqala egqunywe kwaye iqine, ukugqunywa kukuphucula ukuhanjiswa kweglasi ye-photovoltaic, ukugqunywa kukwandisa iipropati zoomatshini zeglasi, amandla okugoba kweglasi eqinileyo aphindwe ka-3 ~ 5 kuneglasi eqhelekileyo, amandla okuchaphazeleka aphindwe ka-5 ~ 10 kuneglasi eqhelekileyo, ukuphucula amandla kodwa kukwaphucula ukhuseleko.
Ukuhamba kwenkqubo yeglasi ye-Photovoltaic
Ukusebenza kweglasi ye-photovoltaic ye-02 kufuna ukuba iglasi ye-photovoltaic ibe nokukhanya okuhle. Ngokubanzi, ukuhanjiswa kokukhanya kweshiti yentsimbi engagqunywanga (ububanzi be-wavelength ukusuka kwi-380nm ukuya kwi-1100nm) kudla ngokuba ngaphezulu kwe-91%, ngelixa ukuhanjiswa kokukhanya kweglasi egqunywe emva kokucubungula nzulu kunokufikelela kwinqanaba le-93.5%. Ukongeza, iglasi ye-photovoltaic kufuneka ihlangabezane nokumelana kwemozulu ethile kunye neempawu zoomatshini. Ngokutsho kwe-GB T 30984.1-2015 "iglasi yamandla elanga inxalenye 1 yeglasi egqunywe ngombala omhlophe kakhulu", ukusebenza okuncinci kweglasi ye-photovoltaic esetyenziselwa iimodyuli ze-photovoltaic kufuneka kuhlangabezane neemfuno ezilandelayo.
Imboni yeglasi ye-Photovoltaic eTshayina
Imiqobo yoshishino lweglasi ye-photovoltaic iphezulu, uxinaniso luphezulu, imveliso ifuna amava aqokelelweyo ixesha elide kunye nenkqubo yemveliso enye, kwaye ifuna utyalo-mali olukhulu lokuqala, umthamo weetoni ezingama-900/ngosuku i-oven yeglasi ye-photovoltaic idinga utyalo-mali lokuqala i-RMB 9, iitoni ezingama-550 zotyalo-mali lwesitovu zithatha malunga ne-3-400 yezigidi zeeyuan, kwaye i-oven enkulu yayineendleko zokuvelisa eziphantsi xa kuthelekiswa ne-oven eqhelekileyo (ukusetyenziswa kwamandla aphantsi ukuya kwi-20%). Ngenxa yoko, ishishini leglasi ye-photovoltaic linesiphumo esicacileyo sesikali, kwaye inani elikhulu letekhnoloji enyibilikisiweyo ikakhulu ezandleni zamashishini aphambili, Amashishini amancinci naphakathi awanawo amandla obuchwephesha kunye namandla oqoqosho okutyala imali ekwakhiweni kweetoni ezili-1000 zee-oven.
Ukususela oko iTshayina yaphula umda wetekhnoloji wokuveliswa kweglasi ye-photovoltaic ngo-2006, ishishini le-photovoltaic lasekhaya liye lakhula ngokukhawuleza kwiminyaka engaphantsi kwe-10. Emva kokuthembela ngokupheleleyo ekuthengisweni kwamanye amazwe, iTshayina iye yaba ngumvelisi omkhulu weglasi ye-photovoltaic kwihlabathi. Ngaphezulu kwe-90% yeemodyuli ze-crystal silicon zehlabathi zisebenzisa iglasi ye-photovoltaic eveliswa eTshayina. Xa kuthelekiswa namashishini angaphandle, iglasi ye-photovoltaic yaseTshayina ineenzuzo ezicacileyo ngomgangatho kunye nexabiso. Ukusukela ngoDisemba 2017, kukho iimveliso zeglasi ezimhlophe kakhulu ezingama-24, ii-kilns ezingama-40 kunye nemigca yemveliso eli-135 eTshayina, enomthamo wemveliso iyonke weetoni ezingama-21,290 ngosuku. Ibalwa ngokwenqanaba lesivuno esiphakathi kushishino se-78%, imveliso yasekhaya yeziqwenga zeglasi ezimhlophe kakhulu ezikrwada malunga neetoni ezili-14,773.20 ngosuku.
Okulindelweyo kwimarike
Unyaka ka-2018 uza kuba ngunyaka wokuqala wokuqaliswa kwezinto ezinamacala amabini, kwaye isabelo semarike sezinto ezinamacala amabini siya kwanda ngokukhawuleza, nto leyo eya kuqhuba ngempumelelo imfuno yeglasi ye-photovoltaic. Ngokwendlela yokubala, imfuno yeglasi ye-photovoltaic iboniswe kwitheyibhile elandelayo. Xa kujongwa ukuba ezinye ii-oven zeglasi ze-photovoltaic ezindala zifuna ukulungiswa okubandayo ngo-2018, amandla okwenyani emveliso yeglasi ye-photovoltaic aya kuba ngaphantsi kunomthamo wemveliso oqhelekileyo, kwaye ukunikezelwa kunye nemfuno yeglasi ye-photovoltaic ngo-2018 kukwizinga elilinganayo.
Ngokweziphumo, ukusukela kwikota yesi-4 ka-2017, ukunikezelwa kweglasi ye-photovoltaic kunye nemfuno kunciphile, ekuqaleni kuka-2018, phantsi kwesiseko seshishini le-photovoltaic kwikota yokuqala akukho xesha lonyaka, i-buck ukunyuka kwexabiso leglasi ye-photovoltaic, iphepha lokugquma kwi-31 yuan ngemitha yesikwere okanye ngaphezulu, ixabiso leglasi kwi-21 yuan ngemitha yesikwere okanye ngaphezulu, ixabiso lokubuyela umva kwamaxabiso liya kwenza inqanaba le-gross margin leshishini le-photovoltaic liphuculwe kakhulu.
