ʻO ka mea huna "gula ʻeleʻele" ma hope o ka ʻoihana semiconductor photovoltaic: ka makemake a me ka hilinaʻi ʻana i ka graphite isostatic

He mea koʻikoʻi loa ka graphite isostatic i nā photovoltaics a me nā semiconductors. Me ka piʻi wikiwiki ʻana o nā ʻoihana graphite isostatic kūloko, ua haki ka monopoly o nā ʻoihana haole ma Kina. Me ka noiʻi kūʻokoʻa mau a me ka hoʻomohala ʻana a me nā holomua ʻenehana, ua like nā hōʻailona hana o kekahi o kā mākou huahana koʻikoʻi me a ʻoi aku paha ma mua o nā mea hoʻokūkū honua. Eia nō naʻe, ma muli o ka hopena pālua o ka hāʻule ʻana o nā kumukūʻai maka a me ka hoʻemi ʻana o nā kumukūʻai e nā mea kūʻai aku hope, ua hoʻomau ka emi ʻana o nā kumukūʻai. I kēia manawa, ʻoi aku ka liʻiliʻi o ka loaʻa kālā o nā huahana haʻahaʻa kūloko ma mua o 20%. Me ka hoʻokuʻu mau ʻana o ka hiki ke hana, ua lawe mālie ʻia nā kaomi hou a me nā pilikia i nā ʻoihana graphite isostatic.

1. He aha ka graphite isostatic?

ʻO ka graphite isostatic e pili ana i nā mea graphite i hana ʻia e ke kaomi isostatic. Ma muli o ke kaomi like ʻana o ka graphite i kaomi ʻia me ka isostatic a me ke kūpaʻa e ke kaomi wai i ka wā o ke kaʻina hana hoʻoheheʻe ʻana, he mau waiwai maikaʻi loa ka mea graphite i hana ʻia. Mai kona hānau ʻana i nā makahiki 1960, ua lilo ka graphite isostatic i alakaʻi i waena o nā mea graphite hou ma muli o kona mau waiwai kū hoʻokahi a me nā ʻano hana like ʻole.

2. Ke kaʻina hana hana graphite isostatic

Ua hōʻike ʻia ke kaʻina hana o ka graphite i kaomi ʻia i ka isostatically ma ke kiʻi. Pono ka graphite isostatic i nā mea maka isotropic structurally. Pono e wili ʻia nā mea maka i mau pauka maikaʻi. Pono e hoʻopili ʻia ka ʻenehana hoʻoheheʻe kaomi isostatic. He lōʻihi loa ke kaʻina hana kālua. I mea e hoʻokō ai i ka nui o ka pahuhopu, pono nā kaʻina hana impregnation a me ka kālua he nui. , ʻoi aku ka lōʻihi o ka manawa graphitization ma mua o ka graphite maʻamau.

3. Hoʻohana ʻia o ka graphite isostatic

He ākea nā noi o ka graphite isostatic, ʻoi aku hoʻi i nā semiconductor a me nā kahua photovoltaic.

Ma ke kahua o nā photovoltaics, hoʻohana nui ʻia ka graphite i kaomi ʻia i ka isostatically i nā ʻāpana graphite i ke kahua wela graphite i loko o nā umu ulu silicon kristal hoʻokahi a ma ke kahua wela graphite i loko o nā umu ingot silicon polycrystalline. ʻO ke kikoʻī, nā clamps no ka hana ʻana i nā mea silicon polycrystalline, nā mea hoʻolaha kinoea no nā umu hydrogenation, nā mea hoʻomehana, nā cylinders insulation a me nā mea hoʻomehana ingot polycrystalline, nā poloka kuhikuhi, a me nā paipu alakaʻi no ka ulu ʻana o ka kristal hoʻokahi a me nā nui liʻiliʻi ʻē aʻe. nā ʻāpana;

Ma ke kahua o nā semiconductors, hiki i nā mea hoʻomehana a me nā cylinders insulation no ka ulu ʻana o ka kristal sapphire ke hoʻohana i ka graphite isostatic a i ʻole ka graphite i hoʻoheheʻe ʻia. Eia kekahi, ʻo nā ʻāpana ʻē aʻe e like me nā ipu hoʻoheheʻe, nā mea hoʻomehana, nā electrodes, nā papa pale wela, a me nā kristal hua Ma kahi o 30 mau ʻano mea paʻa, nā kumu no nā ipu hoʻoheheʻe wili, nā papa poepoe like ʻole, a me nā papa hoʻomālamalama wela i hana ʻia me ka graphite i kaomi ʻia i ka isostatically.
