Hōʻike huahana

Hōʻike o Ultrafine Silver Powder:

Nui ʻāpana: <1um, 1-3um, 3-5um, 5-10um, hiki ke hoʻololi

ʻAno: spherical, flake

Maʻemaʻe: 99.99%

Ka hoʻohana ʻana i ka pauka kālā Ulterfine:

1. ʻO ke ʻano kumu o nā pūnaewele lā o ka lā, ʻo ia ka P-type silicon substrate, N-type layer, hoʻemi ʻia ke kiʻiʻoniʻoni noʻonoʻo (TIO2, SIO2 a i ʻole SI3N4), electrode kālā maikaʻi, electrode alumini hope, a me ka electrode kālā hope. a ua hoʻokumu ʻia ka electrode kālā hope e ka paʻi kalaiwa kala ma o ka paʻi pale a me ka sintering.

2. Conductive paste o solar cell back silver electrode ka mea nui i haku ʻia ma o nā ʻāpana ʻekolu: ka conductive function phase, inorganic binder, organic carrier a me nā mea maka. he aha hou aku, kapauda kalaHe maikaʻi ka hana conduction wela, a ʻoi aku ka maikaʻi ma mua o nā metala makamae ʻē aʻe. Ma nā noi kūpono, ma ke kumu o ka hōʻoiaʻiʻo ʻana i ka hana uila, ʻo ka paʻi kālā hope e pono hoʻi e lawa ka adhesion a me ke kuʻi ʻana.
