Chii chinonzi Solar Graphite Boat?

Muindasitiri yezuva ine simba rezuva (PV) iri kuchinja nekukurumidza, kunyatsorongeka uye hunyanzvi hwezvinhu zvakakosha mukusimudzira mashandiro ekushandura simba. Pakati pemagamba asina kurumbidzwa mune izvi pane Solar Graphite Boat, chikamu chakakosha chakagadzirirwa kugadzirwa kwe semiconductor inodziya zvakanyanya. Yakagadzirwa neVET Energy, mugadziri anotungamira wezvinhu zvepamusoro, mabhoti aya e graphite anoita basa guru mukugadzira masero ezuva anoshanda zvakanyanya. Ngationgororei mashandisirwo awo, hunhu hwawo, uye kuti nei achikosha mu tekinoroji yezuva yemazuva ano.

Chii chinonzi Solar Graphite Boat?

Chikepe cheSolar Graphite imhando yekutakura inoshandiswa muPlasma Enhanced Chemical Vapor Deposition (PECVD), danho guru mukugadzirwa kwemaseru ezuva. Chinochengetedza zvakachengeteka mawafer esilicon panguva yekuiswa kwemafirimu matete, akadai semachira anodzivirira kupenya uye ma layers epassivation, ayo akakosha pakuwedzera kupinza kwechiedza uye kuderedza kurasikirwa kwesimba mumaseru ezuva.

Vet Energy'sMagwa ePECVD graphitezvakagadzirwa kuti zvikwanise kutsungirira mamiriro ezvinhu akaomarara ukuwo zvichivimbisa kufanana uye kuvimbika. Dhizaini yazvo inokanganisa zvakananga kunaka kwemafirimu akaiswa, izvo zvinozosarudza kushanda zvakanaka uye kugara kwenguva refu kwechigadzirwa chezuva chekupedzisira.

Mashandisirwo Akakosha Mukugadzira Solar PV

1. Kuisa Kuvhara Kunodzivirira Kufungisisa
Masero ezuva anoshandisa machira anodzivirira kupenya kuti aderedze kupenya kwechiedza uye awedzere kunyudzwa kwe photon. Chikepe che graphite chinoita kuti ma silicon wafers aonekwe zvakaenzana nemagasi anochinja-chinja panguva yePECVD, zvichigadzira kupenya kwakafanana kunoita kuti chiedza chibatwe zvakanaka.

2. Kupfuura Pamusoro
Ma layers epassivation (semuenzaniso, silicon nitride) anoshandiswa kuderedza zvikanganiso pamusoro uye kurasikirwa ne recombination. Mabhoti eVET Energy anochengetedza kudzora tembiricha kwakaringana uye kuparadzirwa kwegasi, zvakakosha pakugadzira ma layers epassivation asina zvikanganiso anovandudza hupenyu hwemasero.

3. Kugadzirwa Kwepamusoro-soro
Zvakagadzirirwa kuti zvienderane nehurongwa hwePECVD hwemaindasitiri, zvikepe izvi zvinotsigira kugadziriswa nekukurumidza kwemawafer akawanda panguva imwe chete, zvichiwedzera kushanda zvakanaka kwekugadzira mitsetse mikuru yekugadzira solar panel.

Hunhu Hwakanaka Hwezvipenyu zveVET Energy's Graphite Boats

Kushanda kwechikepe chegraphite kunoenderana nehunyanzvi hwacho. VET Energy inosanganisa hunyanzvi hwepamusoro hwegraphite nependi yepamutemo kuti ipe zvinotevera:

1. Kugadzikana Kunoshamisa Kwekupisa
- Tembiricha dzekushanda muPECVD dzinowanzo pfuura 1,200°C. Mabhoti aya anochengetedza chimiro chawo uye anoderedza kuwedzera kwekupisa, zvichiita kuti pave nekuenderana kwakasimba kwewafer kunyangwe painenge ichipisa nekukurumidza/inotonhorera.
- Kupisa kwakanyanya (23 W/m·K) kunoita kuti kupisa kupararire zvakaenzana, zvichidzivirira nzvimbo dzinopisa dzinogona kukuvadza mawafer.

2. Kuramba Kemikari
- Haipindi magasi anoparadza akadai seNH₃ neSiH₄, ayo anowanzoonekwa muPECVD. Izvi zvinowedzera hupenyu hwechikepe uye zvinoderedza njodzi dzekusvibiswa.

3. Dhizaini Yekuyerera Kwegasi Rakagadziriswa
- Magadzirirwo epfuma anoita kuti gasi rifambe zvakaenzana pamawafer ese, zvichikosha kuti firimu rive rakakora uye rive rakafanana. Izvi zvinoreva kuti maseru ezuva anoshanda zvakanyanya.

4. Hupenyu Hurefu hwebasa
- Mapurasitiki eCVD epamusoro (semuenzaniso, silicon carbide kana tantalum carbide) anowedzera kugara kwenguva refu. Semuenzaniso, zvikamu zveVET Energy zvakaputirwa neTaC zvinotsungirira tembiricha iri pamusoro pe2,500°C uye zvinodzivisa ngura yesimbi yakanyungudutswa, hupenyu hunowedzera katatu kana zvichienzaniswa nezvinhu zvemazuva ose.

5. Kugona Kwekugadzirisa
- Zviyero nemachira akagadzirirwa kuti zvienderane nemidziyo chaiyo (semuenzaniso, saizi dzewafer kubva pa4-inch kusvika 12-inch) uye zvinodiwa pakugadzirisa, zvichiita kuti zvive pachena kuti zvakabatana zvakanaka mumitsetse yekugadzira iripo.

Kudzivirira kwakanyanya kupisa

- Mabhoti eGraphite anogona kutsungirira tembiricha yakanyanya ye1,200°C~2,500°C, uye ane tembiricha yakaderera yekuwedzera mukati meiyi range (semuenzaniso, tembiricha yekuwedzera yezvigadzirwa zveVET Energy i4.8×10⁻⁶/°C), izvo zvinogona kuchengetedza kugadzikana kwechimiro uye kurongeka kwewafer. Kusiyana neizvi, tembiricha yepamusoro yebhoti dzequartz inowanzo kuve 1,200°C, uye kushandiswa kwenguva refu kwetembiricha yepamusoro kunogona kukonzera deformation kana kuputika.

Kufambisa kwakanaka kwekupisa uye kufanana

- Kufambiswa kwemafuta e graphite (inenge 23 W/m·K) kwakanyanya kupfuura kwe quartz (inenge 1.4 W/m·K), saka mumabasa akadai se PECVD (plasma enhanced chemical vapor deposition), zvikepe zve graphite zvinogona kuwana kugoverwa kwekupisa kwakafanana, kuderedza mutsauko muukobvu hwe wafer film, uye kuvandudza mhando ye passivation layer ye solar cells.

Kuramba kwakasimba kunokonzerwa nemakemikari ngura

- Mabhoti eGraphite anoshivirira zvakanyanya magasi anoparadza akadai seNH₃ (ammonia) neSiH₄ (silane), uye akakodzera maitiro anoda kugara achisangana nemagasi anochinja-chinja (senge tubular PERC cell coating). Pamusoro pezvo, nekuputira pamusoro nesilicon carbide (SiC) kana tantalum carbide (TaC), hupenyu hwebasa hunogona kuwedzerwa (semuenzaniso, VET Energy's TaC coating inogona kumira tembiricha yepamusoro ye2,500°C).

Mari uye hupenyu hurefu

- Magwa eGraphite anogara kwenguva refu uye anogona kushandiswazve kakawanda pamichina yekugadzira maindasitiri, uye mari yekugadzirisa yakaderera pane yemagwa equartz. Semuenzaniso, magwa eGraphite akagadzirwa neVET Energy anogona kutsigira zvinodiwa pakugadzira mawafers e4~12-inch kuburikidza nekugadzirwa kwakagadziridzwa, zvichideredza mutengo wekuita pawafer imwe neimwe.

Sei Uchifanira KusarudzaSimba reVET?

VET Energy inoonekwa seimwe yemakambani epamusoro-soro ekugadzira zvinhu nekuda kwe:
- Nyanzvi dzeR&D: Chikwata chehunyanzvi chinobva kumasangano makuru ekutsvagisa, kusanganisira Chinese Academy of Sciences, chinotungamidza hunyanzvi hutsva mune zvesainzi yezvinhu.
- Kuvimbisa Hunhu: Masisitimu ekudzora hunhu akasimba uye matekinoroji ekuputira ane patent (semuenzaniso, CVD layers dzakasungwa zvakasimba) zvinoita kuti chigadzirwa chive chakavimbika.
- Kukurumidza Kupindura: Mhinduro dzakagadzirirwa uye nguva dzekutumira nekukurumidza (semuenzaniso, mazuva gumi nemashanu ekutenga maodha ari pasi pe1,000 mayuniti) zvinoderedza nguva yekushanda kwevagadziri.
- Kuzivikanwa kwevatengi: Mushure memakore ekunaya kwemvura uye kuunganidzwa kwemagetsi, chikepe cheVET Energy che graphite chezuva chakatumirwa kunyika dzinopfuura 100 nenzvimbo, uye mugove waro wemusika muEurope neUnited States wakakwira kusvika 70%, uchiwana rumbidzo huru uye rumbidzo kubva kune vatengi vakawanda. Ndiyo sarudzo yako yakanakisisa.
