Iyini i-Solar Panel Manufacturing?
Ukukhiqizwa kwamaphaneli elanga kuyinqubo yezobuchwepheshe eyinkimbinkimbi eguqula amandla elanga abe ugesi osebenzisekayo.
Lolu shintsho lwenzeka ngomphumela we-photovoltaic, owatholwa ngo-1839 ngu-Alexandre Edmond Becquerel,
okuyinto
yenza amaseli elanga akwazi ukukhiqiza amandla kagesi lapho evezwe ekukhanyeni.
I inqubo yokukhiqiza iphaneli yelanga kuhilela izigaba ezimbalwa ezibalulekile, kusukela ku-silicon eluhlaza
ukukhishwa ekufakweni kokugcina kwamamojula we-photovoltaic ophahleni lwezindlu noma ezitshalweni zamandla elanga.
Izinyathelo Eziyisi-7 Eziyisisekelo Zokukhiqiza Ilanga
1. Ukukhishwa kwe-Silicon nokuhlanzwa
Okokuqala isinyathelo sokukhiqiza ilanga iqala ngokukhipha i-silicon esihlabathini se-quartz (SiO₂).
I-silicon ibamba cishe u-90% wamaseli e-photovoltaic amanje.
Inqubo yokuhlanza:
- Ukuncishiswa kwe-quartz ezithandweni zikagesi ze-arc ku-3,632°F (2,000°C)
- Ukukhiqizwa kwe-silicon metallurgical (98% ubumsulwa)
- Ukuhlanzwa kwamakhemikhali ngenqubo ye-Siemens ukuze kuzuzwe ubumsulwa obungu-99.9999%.
- Ukukhiqizwa kwe-silicon yezinga lelanga
Lesi sigaba sisebenzisa amanani amakhulu wamandla, amelela cishe u-45% wengqikithi ye-carbon footprint yephaneli yelanga.
2. Ukudala I-Crystalline Silicon Ingots
Uma isicwengiwe, i-silicon iyancibilika futhi ifakwe ikristalu ukuze yakhe i-cylindrical ingots (i-monocrystalline) noma amabhlogo ayizikwele.
(i-polycrystalline).
Izindlela ezimbili eziyinhloko:
- Indlela yeCzochralski: ikhiqiza i-silicon ye-monocrystalline esebenza kahle kakhulu (20-22%)
- Indlela yokusakaza: yenza i-silicon ye-polycrystalline, engabizi kakhulu kodwa ephansi
ukusebenza kahle
(15-17%)
3. I-Wafer Slicing
Ama-ingots abe esesikwa abe amadiski amancane abizwa ngokuthi izinkwa eziwucwecwe usebenzisa amasaha ocingo lwedayimane. Lokhu
isinyathelo sokukhiqiza esibucayi inquma ukushuba kokugcina kwamaseli e-photovoltaic.
Izici ze-Wafer:
- Ubukhulu: 180 kuya ku-200 micrometer
- Ukulahlekelwa kwezinto: cishe ama-50% ngesikhathi sokusika
- Indawo epholishiwe futhi yenziwe ngendlela efanele ukuze kuthuthukiswe ukumunca ukukhanya
4. Ukwakhiwa Kweseli Solar
Lesi sigaba siguqula amawafa abe amaseli asebenzayo akwazi ukukhiqiza ugesi.
Inqubo ye-Doping:
- P-uhlobo lwe-doping: ukwengeza i-boron ukuze udale amashaji avumayo
- I-N-uhlobo lwe-doping: kufaka i-phosphorus ngamashaji angalungile
- Ukwakhiwa kwe-PN junction, inhliziyo yomphumela we-photovoltaic
Ukwengeza othintana nabo ngogesi:
- Ukuphrinta isikrini kokunamathisela okuguquguqukayo (isiliva, i-aluminium)
- Ukudubula kwezinga lokushisa eliphezulu ukuze kuhlanganiswe abathintwayo
- Ukuhlolwa kukagesi kweseli ngalinye
5. I-Solar Module Assembly
Amaseli ngamanye ahlanganiswa ukuze akheke ama-solar panel aphelele.
Isakhiwo semojuli:
- Ingilazi eqinile ephikisana ne-reflective (ubuso bangaphambili)
- EVA (Ethylene Vinyl Acetate) encapsulant
- Amaseli e-photovoltaic axhunyiwe
- I-backsheet evikelayo (ubuso bangemuva)
- Uhlaka lwe-Aluminium lokuqina
Kwakamuva emisha iphaneli
ukukhiqiza faka i-TOPCon kanye nobuchwepheshe be-heterojunction, okunika amandla ukusebenza kahle
ngaphezu kwama-23%.
6. Ukuhlolwa Kwekhwalithi Nokuqinisekiswa
Iphaneli ngayinye yelanga iyadlula ukuhlola okunzima ukuqinisekisa ukusebenza nokuqina:
- Ukuhlolwa kwamandla ngaphansi kwezimo zokuhlola ezijwayelekile (STC)
- Ukuhlolwa kokufakwa kukagesi
- Ukuhlola ukumelana nesimo sezulu
- Isitifiketi samazwe ngamazwe (IEC 61215, IEC 61730)
7. Ukufakwa kanye Nokugunyazwa
Isinyathelo sokugcina sibandakanya ukufaka amaphaneli endaweni yawo:
Ukufakwa kwendawo yokuhlala:
- Ukucwaninga okunokwenzeka usebenzisa amathuluzi afanaPVGIS24
- Ukufakwa kophahla noma phansi
- Ukuxhunywa kukagesi nokuthunywa
Ukufakwa kwezohwebo:
- Izitshalo ezinkulu zamandla elanga
- Ukuhlanganiswa kwegridi
- Izinhlelo zokuqapha ezithuthukile
