Ka hoʻohana ʻana i nā seramika silika carbide ma ke kahua photovoltaic

① He mea lawe nui ia i ke kaʻina hana o nā cell photovoltaic
Ma waena o ka silicon carbide structural ceramics, ua hoʻomohala ka ʻoihana photovoltaic o ke kākoʻo moku carbide kiʻekiʻe i kahi kiʻekiʻe o ka pōmaikaʻi, e lilo i koho maikaʻi no nā mea lawe kī nui i ke kaʻina hana o nā cell photovoltaic, a ua hoʻopiʻi kāna noi mākeke i ka hoʻonui ʻana i ka manaʻo mai ka ʻoihana. .

I kēia manawa, hoʻohana mau ʻia nā kākoʻo waʻa, nā pahu waʻa, nā paipu paipu, a me nā mea ʻē aʻe i hana ʻia me ka quartz, akā ua kaupalena ʻia lākou e nā kumu wai kola quartz one hoʻomaʻemaʻe kiʻekiʻe o ka home a me ka honua, a he liʻiliʻi ka hiki ke hana. Loaʻa ka lako paʻa a me ka koi no ke one quartz maʻemaʻe kiʻekiʻe, a ke holo nei ke kumukūʻai ma kahi kiʻekiʻe no ka manawa lōʻihi, a ua pōkole ke ola lawelawe. Ke hoʻohālikelike ʻia me nā mea quartz, nā kākoʻo waʻa, nā pahu waʻa, nā paipu paipu a me nā huahana ʻē aʻe i hana ʻia me nā mea silicon carbide maikaʻi ka thermal stability, ʻaʻohe deformation i ke kiʻekiʻe wela, a ʻaʻohe mea hoʻohaumia i hoʻopōʻino ʻia. Ma ke ʻano he mea ʻokoʻa maikaʻi loa no nā huahana quartz, hiki ke ola o ka lawelawe ma mua o 1 makahiki, hiki ke hōʻemi nui i ke kumukūʻai hoʻohana a me ka nalowale o ka hiki ke hana ʻia e ka mālama ʻana a me ka hoʻoponopono. ʻIke ʻia ka pōmaikaʻi o ke kumukūʻai, a ʻo kāna noi noi ma ke ʻano he mea lawe i ke kahua photovoltaic he ākea.

② Hiki ke hoʻohana ʻia ma ke ʻano he mea wela wela no nā ʻōnaehana mana o ka lā
Hoʻomaikaʻi nui ʻia nā ʻōnaehana hoʻomohala wela o ka hale kiaʻi i ka mana o ka lā ma muli o ko lākou kiʻekiʻe kiʻekiʻe (200 ~ 1000kW/㎡), kiʻekiʻe ka wela wela, haʻahaʻa haʻahaʻa wela, ʻōnaehana maʻalahi a me ka hana kiʻekiʻe. E like me ka mea nui o ka hale kiaʻi solar thermal power generation, pono ka absorber e kū i ka radiation intensity 200-300 mau manawa ʻoi aku ka ikaika ma mua o ka mālamalama maoli, a hiki ke kiʻekiʻe ka mahana hana ma mua o hoʻokahi tausani degere Celsius, no laila he mea nui loa kāna hana. no ka hana paʻa a me ka maikaʻi o ka hana ʻana o ka ʻōnaehana mana wela. ʻO ka mahana hana o nā mea hoʻoheheʻe metala maʻamau i kaupalena ʻia, e hana ana i nā mea hoʻoheheʻe seramika i wahi wela noiʻi hou. Hoʻohana pinepine ʻia nā seramika alumina, cordierite ceramics, a me silicon carbide ceramics e like me nā mea absorber.

hale kiaʻi hoʻoheheʻe ʻana i ka mana o ka lā

Ma waena o lākou, he mau hiʻohiʻona maikaʻi loa ka silicon carbide ceramics e like me ka ikaika kiʻekiʻe, ka nui o ka ʻāina kikoʻī nui, ka pale ʻana i ka corrosion, ka pale ʻana i ka oxidation, ka insulation thermal maikaʻi, ke kūpaʻa haʻalulu a me ke kūpaʻa wela kiʻekiʻe. Ke hoʻohālikelike ʻia me nā mea alumina a me nā cordierite ceramic absorber, ʻoi aku ka maikaʻi o ka hana wela kiʻekiʻe. ʻO ka hoʻohana ʻana i kahi mea hoʻoheheʻe wela i hana ʻia me ka carbide silicon sintered e hiki ai i ka mea lawe wela ke hoʻokō i kahi ea wela o waho a hiki i 1200 ° C me ka ʻole o ka pōʻino.
