Liphanele tsa letsatsi li entsoe ka eng?
Liphanele tsa letsatsi tse sebelisoang haholo khoebong kajeno li oela likarolong tse peli tse akaretsang:
- Liphanele tse thehiloeng ho silicon(polycrystalline kapa monocrystalline)
- Liphanele tsa lifilimi tse tšesaane (cadmium telluride, amorphous silicon, kapa CIGS)
Se latelang ke karohano e tloaelehileng ea thepa ka har'a liphanele tse thehiloeng ho silicon:
- Glass(ka pele)
- aluminium(foreime)
- Li-wafers tsa silicon(lisele tsa letsatsi)
- Encapsulant(hangata EVA)
- Backsheet(hangata e entsoe ka polasetiki kapa polymer)
- Silevera, koporo, le li-trace metals(bakeng sa potoloho)
Hoa makatsa ho haella lethathamong lena: mercury.
Joale ke hobane’ng ha potso ee e hlaha qalong? Libakeng tse ling, litaba tse mabapi le lirafshoa tse boima li entse hore mercury e ferekanngoe le lintho tse ling tse kang cadmium (e sebelisoang liphanele tse itseng tsa lifilimi tse tšesaane, empa eseng liphanele tsa silicon).
Na Mercury kapa Lintho Tse Ling Tse Kotsi li Fumaneha Liphanele Tsa Letsatsi?
Ha re nepahale.

Mercury ha e sebelisoe liphanele tsa letsatsi. Sena se tiisoa ke bahlahisi, tlhahlobo ea potoloho ea bophelo, le melaoana ea naha. Litaelo tsa US EPA, EU RoHS, le litataiso tsa METI tsa Japane kaofela li thibela kapa li thibela tšebeliso ea mercury bakeng sa lisebelisoa tsa letsatsi.
Mohlala oa mohlala: California Waste Classification le Tlhakiso
California e tšoara liphanele tsa letsatsi tlas'a Molao oa Universal Waste Rule ho li sebelisa hape ka mokhoa o sireletsehileng. Ka 2021, Lefapha la California la Taolo ea Lintho Tse Chefo (DTSC) le ile la tiisa hape hore li-module tse tloaelehileng tsa solar ha li na mercury ka hona ha se litšila tsa mercury.

Joale Pherekano e Tsoa Hokae?
Nako le nako, lipuisano tsa tikoloho li etsa hore liphanele tsa letsatsi li be sehlopheng se akaretsang sa "electronics", seo pele se neng se e-na le likaroloana tsa mercury (joaloka li-thermostat tsa khale kapa mabone a fluorescent).

Tšōmo e 'ngoe e tloaelehileng: Liphanele tsa CdTe tsa filimi e tšesaane li na le cadmium, e chefo-empa e fapane ka lik'hemik'hale le tikoloho le mercury. CdTe e boetse e kenyelelitsoe, e fokotsa kotsi ntle le haeba liphanele li robehile le ho tšoaroa hampe.
Na liphanele tse senyehileng kapa tse tsofetseng li ka lokolla lintho tse chefo?
Eseng mercury - empa ka linako tse ling, liphanele tsa CdTe tse robehileng li tlameha ho tšoaroa ka hloko. Boholo ba li-installer le li-recyclers hona joale li sebelisa mekhoa e tiisitsoeng ea e-waste ho qoba ho pepesehela lintho tse kotsi.
