Nekuenderera mberi kuri kuita nyika yanhasi, simba risingadzokerike riri kuramba richipera, uye nzanga yevanhu iri kuramba ichikurumidzira kushandisa simba rinogona kudzokororwa rinomiririrwa ne“mhepo, chiedza, mvura nenyukireya”. Kuenzaniswa nemamwe magetsi anovandudzwa, vanhu vane ruzivo rwakakura, rwakachengeteka uye rwakavimbika rwekushandisa simba rezuva. Pakati pavo, iyo photovoltaic cell indasitiri ine yakakwirira-kuchena silicon sezvo iyo substrate yakagadzira zvakanyanya nekukurumidza. Pakazopera 2023, nyika yangu cumulative solar photovoltaic yakaiswa simba rakapfuura 250 gigawatts, uye photovoltaic simba chizvarwa asvika 266.3 bhiriyoni kWh, kuwedzera anenge 30% gore-on-gore, uye ichangobva akawedzera simba kugadzirwa simba iri mamiriyoni 78.42 kilowatts, kuwedzera 1% gore-5. Kubva pakupera kwaChikumi, iyo yakawedzera yakaiswa simba rekugadzira magetsi emagetsi angangoita 470 miriyoni kilowatts, iyo yakapfuura hydropower kuti ive yechipiri pakukura magetsi munyika yangu.
Kunyange iyo indasitiri yephotovoltaic iri kukura nekukurumidza, iyo nyowani yezvigadzirwa indasitiri inoitsigira iri kukurawo nekukurumidza. Quartz zvikamu zvakadaiquartz crucibles, zvikepe zve quartz, uye mabhodhoro e quartz zviri pakati pavo, zvichiita basa rinokosha mukugadzirwa kwe photovoltaic. Semuenzaniso, quartz crucibles inoshandiswa kubata silicon yakanyungudutswa mukugadzirwa kwesilicon rods uye silicon ingots; mabhoti equartz, machubhu, mabhodhoro, matangi ekuchenesa, nezvimwe zvinotamba basa rekubereka mukupararira, kuchenesa uye mamwe maitiro ekubatanidza mukugadzirwa kwemasero ezuva, nezvimwewo, kuve nechokwadi chekuchena uye kunaka kwezvinhu zvesilicon.
Kushandiswa kukuru kwezvikamu zve quartz zvekugadzira photovoltaic
Mukugadzira ma solar photovoltaic masero, ma silicon wafer anoiswa pachikepe, uye chikepe chinoiswa pawafer chikepe chinotsigira kupararira, LPCVD uye mamwe maitiro ekupisa, nepo silicon carbide cantilever paddle ndiyo yakakosha kurodha chikamu chekufambisa chitsigiro chechikepe chinotakura silicon wafers kupinda nekubuda muchoto chekudziya. Sezvinoratidzwa mumufananidzo uri pazasi, iyo silicon carbide cantilever paddle inogona kuve nechokwadi che concentricity yesilicon wafer uye chubhu yevira, nekudaro ichiita kuti kupararira uye passivation kuve yunifomu. Panguva imwecheteyo, haina kusvibiswa-isina uye isina kuremara pakupisa kwakanyanya, ine yakanaka yekupisa kutyisa kusagadzikana uye yakakura kutakura mutoro, uye yakashandiswa zvakanyanya mumunda wephotovoltaic masero.

Mune yakapfava kumhara kupararira maitiro, yechinyakare quartz boat uyechikepe chewafertsigiro inoda kuisa silicon wafer pamwe chete nequartz boat rutsigiro muchubhu yequartz muvira rekuparadzira. Mune yega yega yekuparadzira maitiro, iyo quartz chikepe inotsigira yakazadzwa nesilicon wafer inoiswa pasilicon carbide paddle. Mushure mekunge silicon carbide paddle yapinda muchubhu yequartz, paddle inonyura kuisa pasi quartz boat support uye silicon wafer, yobva yamhanya zvishoma nezvishoma ichidzokera kwayakatangira. Mushure memaitiro ega ega, iyo quartz chikepe rutsigiro inoda kubviswa kubvasilicon carbide paddle. Kushanda kwakadai kunowanzoitika kuchaita kuti quartz chikepe chitsigire kupera kwenguva yakareba. Kamwe chikepe chequartz chichitsigira kutsemuka uye kutsemuka, iyo yese quartz chikepe rutsigiro inodonha kubva pasilicon carbide paddle, uye yobva yakuvadza zvikamu zvequartz, silicon wafers uye silicon carbide paddles pazasi. Iyo silicon carbide paddle inodhura uye haigone kugadzirwa. Kana njodzi yangoitika, inokonzeresa kurasikirwa kukuru kwemidziyo.
Muchirongwa cheLPCVD, kwete chete matambudziko ataurwa pamusoro pekupisa kwemafuta anoitika, asi sezvo chirongwa cheLPCVD chichida gasi re silane kuti ripfuure nepakati pesilicon wafer, iyo yenguva refu maitiro ichaitawo silicon coating pawafer chikepe tsigiro uye chikepe chewafer. Pamusana pekusawirirana kwemafuta ekuwedzera kwemafuta e-silicone yakavharwa uye quartz, chitsigiro chechikepe uye chikepe chichaputika, uye hupenyu huchaderedzwa zvakanyanya. Hupenyu hurefu hwezvikepe zvequartz zvakajairwa uye zvitsigiso zvechikepe muLPCVD maitiro anowanzo 2 kusvika 3 mwedzi chete. Nokudaro, zvinonyanya kukosha kuvandudza zvinhu zvekutsigira chikepe kuti uwedzere simba uye hupenyu hwebasa rekutsigirwa kwechikepe kudzivirira njodzi dzakadaro.
Muchidimbu, sezvo nguva yekushanda uye nhamba yenguva inowedzera panguva yekugadzirwa kwemasero ezuva, zvikepe zve quartz uye zvimwe zvikamu zvinowanzosangana nekuputika kwakavanzika kana kunyange kuputsika. Hupenyu hwemabhoti equartz uye machubhu equartz mumitsara yazvino yekugadzira muChina ingangoita mwedzi 3-6, uye inoda kuvharwa nguva nenguva pakuchenesa, kugadzirisa, uye kutsiva vatakuri vequartz. Uyezve, iyo yakakwira-yakachena quartz jecha rinoshandiswa seyakasvibirira yezvikamu zvequartz parizvino iri mumamiriro ekupa uye kudiwa, uye mutengo wanga uchishanda padanho repamusoro kwenguva yakareba, izvo zviri pachena kuti hazvibatsiri kuvandudza kushanda kwekugadzira uye hupfumi.
Silicon carbide ceramics"svika"
Ikozvino, vanhu vauya nechinhu chine kuita kuri nani kutsiva zvimwe zvequartz-silicon carbide ceramics.
Silicon carbide ceramics ine yakanaka mechanical simba, kugadzikana kwekupisa, kukwira kwekushisa kwekushisa, oxidation kuramba, kupisa kwekushisa kwekudzivirira uye kemikari yekudzivirira kwemarara, uye inoshandiswa zvakanyanya munzvimbo dzinopisa dzakadai sesimbi, michina, simba idzva, uye zvekuvakisa nemakemikari. Kuita kwayo kunokwanawo kupararira kweTOPcon masero mukugadzira photovoltaic, LPCVD (low pressure chemical vapor deposition), PECVD (plasma chemical vapor deposition) uye mamwe maitiro ekupisa.

Zvichifananidzwa nezvinhu zvechinyakare zvequartz, zvitsigiso zvemabhoti, mabhoti, uye zvigadzirwa zvechubhu zvakagadzirwa nesilicon carbide ceramic zvinhu zvine simba rakakwirira, kugadzikana kwemafuta kuri nani, hakuna deformation pakupisa kwakanyanya, uye hupenyu hunopfuura ka5 nguva yezvigadzirwa zvequartz, izvo zvinogona kuderedza zvakanyanya mutengo wekushandisa uye kurasikirwa kwesimba kunokonzerwa nekugadzirisa uye kuderera. Kukosha kwemutengo kuri pachena, uye kwakabva zvinhu zvakakura.
Pakati pavo, reaction sintered silicon carbide (RBSiC) ine yakaderera sintering tembiricha, yakaderera mutengo wekugadzira, yakakwira densification, uye inenge isina vhoriyamu shrinkage panguva yekupindura sintering. Inonyanya kukodzera kugadzirirwa kwezvikamu zvakakura-mahombe uye zvakaoma-zvakaoma. Naizvozvo, inonyanya kukodzera kugadzirwa kwezvakakura-hukuru uye zvakaoma zvigadzirwa senge zvitsigiro zvezvikepe, zvikepe, cantilever paddles, choto machubhu, nezvimwe.
Silicon carbide wafer mabhotizvakare vane tarisiro huru dzebudiriro mune ramangwana. Pasinei nehurongwa hweLPCVD kana nzira yekuwedzera boron, hupenyu hwechikepe chequartz hushoma, uye kupisa kwekuwedzera kwehuwandu hwezvinhu zve quartz hazvienderani neiyo yesilicon carbide zvinhu. Naizvozvo, zviri nyore kuve nekutsauka munzira yekufananidza nesilicon carbide boat holder pakupisa kwakanyanya, izvo zvinotungamira kune mamiriro ekuzunza chikepe kana kutoputsa chikepe. Iyo silicon carbide bhoti inotora nzira yekuumba imwe-chidimbu kuumba uye yakazara kugadzirisa. Chimiro chayo uye chinzvimbo chekushivirira zvinodiwa zvakakwira, uye inobatirana zvirinani nesilicon carbide boat holder. Pamusoro pezvo, silicon carbide ine simba rakawanda, uye chikepe hachinyanyi kuputsika nekuda kwekudhumhana kwevanhu kupfuura chikepe chequartz.
Silicon carbide wafer boat
Iyo chubhu yehuni ndiyo inonyanya kupisa kupisa chikamu chechoto, iyo inobata basa mukuvhara uye yunifomu kupisa kupisa. Kana ichienzaniswa nequartz furnace tubes, silicon carbide furnace tubes ine yakanaka thermal conductivity, yunifomu yekudziya, uye yakanaka kugadzikana kwemafuta, uye hupenyu hwavo hunodarika ka5 pane hwequartz chubhu.
Summary
Kazhinji, ingave maererano nekuita kwechigadzirwa kana mutengo wekushandisa, silicon carbide ceramic zvinhu zvine zvakanakira kupfuura zvinhu zvequartz mune zvimwe zvikamu zve solar cell field. Iko kushandiswa kwesilicon carbide ceramic zvinhu muindasitiri yephotovoltaic kwakabatsira zvakanyanya makambani ephotovoltaic kuderedza mutengo wekudyara wezvinhu zvekubatsira uye kuvandudza kunaka kwechigadzirwa uye kukwikwidza. Mune ramangwana, nekushandiswa kwakakura kwemachubhu makuru esilicon carbide furnace, mabhoti e-silicon carbide uye zvitsigiro zvezvikepe zvakakura uye nekudzikiswa kwemari, kushandiswa kwesilicon carbide ceramic zvinhu mumunda we photovoltaic cell kuchava chinhu chinokosha mukuvandudza kushanda kwechiedza chekushandura simba uye kuderedza mari yeindasitiri mumunda we photovoltaic kugadzirwa kuchava nekukosha kwekugadzirwa kwe photovoltaic. simba idzva.
