Me ka hoʻomau mau ʻana o ka honua i kēia mau lā, ke ulu nei ka ikehu hiki ʻole ke hoʻololi hou ʻia, a ke koi nui nei ka lāhui kanaka e hoʻohana i ka ikehu hou i hōʻike ʻia e "ka makani, ka māmā, ka wai a me ka nuklea". Ke hoʻohālikelike ʻia me nā kumu ikehu ʻē aʻe, loaʻa i nā kānaka ka ʻenehana ʻoi loa, palekana a hilinaʻi no ka hoʻohana ʻana i ka ikehu lā. Ma waena o lākou, ʻo ka ʻoihana photovoltaic cell me ka silika maʻemaʻe kiʻekiʻe e like me ka substrate i ulu wikiwiki loa. I ka hopena o 2023, ua ʻoi aku ka nui o ka mana o ka photovoltaic solar i hoʻokomo ʻia ma mua o 250 gigawatts, a ua hōʻea ka mana o ka mana photovoltaic i 266.3 biliona kWh, kahi piʻi o 30% o ka makahiki-ma-makahiki, a ʻo ka mana o ka mana hana hou he 78.42 miliona. kilowatts, he hoʻonui o 154% makahiki-ma-makahiki. Ma ka hopena o Iune, ʻo ka huina kumulative i hoʻokomo ʻia o ka mana photovoltaic ma kahi o 470 miliona kilowatts, ua ʻoi aku ma mua o ka hydropower e lilo i lua kumu mana nui loa ma koʻu ʻāina.
ʻOiai ke ulu wikiwiki nei ka ʻoihana photovoltaic, ke ulu wikiwiki nei ka ʻoihana mea hou e kākoʻo ana iā ia. Nā ʻāpana quartz e like mequartz crucibles, nā moku quartz, a me nā'ōmole quartz i waena o lākou, e pāʻani ana i kahi kuleana nui i ka hana hana photovoltaic. No ka laʻana, hoʻohana ʻia nā kīʻaha quartz no ka hoʻopaʻa ʻana i ke silika hoʻoheheʻe ʻia i ka hana ʻana i nā koʻokoʻo silicon a me nā ingots silicon; ʻO nā moku quartz, nā paipu, nā ʻōmole, nā pahu hoʻomaʻemaʻe, a me nā mea ʻē aʻe e pāʻani i kahi hana i ka diffusion, hoʻomaʻemaʻe a me nā loulou kaʻina hana ʻē aʻe i ka hana ʻana o nā cell solar, etc., e hōʻoia ana i ka maʻemaʻe a me ka maikaʻi o nā mea silicon.
Nā noi nui o nā ʻāpana quartz no ka hana photovoltaic
Ma ke kaʻina hana o nā pūnaewele photovoltaic solar, kau ʻia nā wafer silika ma luna o kahi waʻa wafer, a kau ʻia ka waʻa ma luna o ke kākoʻo wafer waʻa no ka diffusion, LPCVD a me nā kaʻina hana wela ʻē aʻe, ʻoiai ʻo ka hoe silicon carbide cantilever ka mea hoʻouka nui no ka neʻe ʻana. ke kākoʻo waʻa e lawe ana i nā wafer silika i loko a i waho o ka umu wela. E like me ka mea i hōʻike ʻia ma ke kiʻi ma lalo nei, hiki i ka hoe silicon carbide cantilever hiki ke hōʻoia i ka concentricity o ka wafer silicon a me ka paipu umu, a laila e hoʻonui ai i ka diffusion a me ka passivation. I ka manawa like, he pollution-free a ʻaʻole deformed i nā wela kiʻekiʻe, maikaʻi ke kūpaʻa haʻalulu wela a me ka hiki ke hoʻouka nui, a ua hoʻohana nui ʻia i ke kula o nā kiʻi photovoltaic.
Kiʻi kiʻi kiʻi o ka hoʻouka ʻana i nā ʻāpana
I ke kaʻina hoʻopuehu ʻāina palupalu, ka waʻa quartz kuʻuna awaʻa waʻaPono ke kākoʻo e hoʻokomo i ka wafer silika me ke kākoʻo waʻa quartz i loko o ka paipu quartz i loko o ka umu diffusion. I kēlā me kēia kaʻina hoʻolaha, kau ʻia ke kākoʻo waʻa quartz i hoʻopiha ʻia me nā wafer silika ma ka hoe carbide silicon. Ma hope o ke komo ʻana o ka hoe silicon carbide i loko o ka paipu quartz, e iho koke ka hoe no ka waiho ʻana i ke kākoʻo waʻa quartz a me ka wafer silicon, a laila e holo mālie i ke kumu. Ma hope o kēlā me kēia kaʻina hana, pono e wehe ʻia ke kākoʻo moku quartz mai kahoe kapili silika. ʻO ia hana pinepine e hoʻopau i ke kākoʻo waʻa quartz no ka manawa lōʻihi. I ka wā e hāʻule ai ke kākoʻo waʻa quartz a nahā, e hāʻule ke kākoʻo waʻa quartz holoʻokoʻa mai ka hoe silicon carbide, a laila e hōʻino i nā ʻāpana quartz, nā wafer silika a me nā hoe silicon carbide ma lalo. He pipiʻi ka hoe silicon carbide a ʻaʻole hiki ke hoʻoponopono ʻia. I ka wā e loaʻa ai kahi pōʻino, e lilo ia i mea nui i ka poho waiwai.
Ma ke kaʻina hana LPCVD, ʻaʻole wale nā pilikia koʻikoʻi wela i ʻōlelo ʻia ma luna, akā no ka mea e koi ana ke kaʻina LPCVD i ke kinoea silane e hele i loko o ka wafer silika, e hana pū ka hana lōʻihi i kahi uhi silika ma ke kākoʻo wafer waʻa a me ka waʻa waʻa. Ma muli o ka like ʻole o ka hoʻonui ʻana o ka wela o ka silikoni i uhi ʻia a me ka quartz, e haki ke kākoʻo o ka waʻa a me ka moku, a e hoʻemi nui ʻia ke ola. ʻO ka lōʻihi o ke ola o nā moku quartz maʻamau a me nā kākoʻo waʻa i ke kaʻina LPCVD he 2 a 3 mau mahina wale nō. No laila, he mea koʻikoʻi ka hoʻomaikaʻi ʻana i nā mea kākoʻo waʻa e hoʻonui ai i ka ikaika a me ke ola lawelawe o ke kākoʻo waʻa e pale aku ai i ia mau pōʻino.
I ka pōkole, e like me ka hoʻonui ʻana o ke kaʻina hana a me ka nui o nā manawa i ka wā o ka hana ʻana o nā cell solar, hiki i nā waʻa quartz a me nā mea ʻē aʻe ke maʻalahi i nā māwae huna a i ʻole nāha. ʻO ke ola o nā moku quartz a me nā paipu quartz i nā laina hana nui o kēia manawa ma Kina e pili ana i 3-6 mau mahina, a pono lākou e pani mau ʻia no ka hoʻomaʻemaʻe, mālama ʻana, a me ka hoʻololi ʻana i nā mea lawe quartz. Eia kekahi, ʻo ke one quartz maʻemaʻe kiʻekiʻe i hoʻohana ʻia e like me ka mea maka no nā ʻāpana quartz i kēia manawa i kahi kūlana paʻa a me ka koi, a ke holo nei ke kumukūʻai ma kahi kiʻekiʻe no ka manawa lōʻihi, ʻaʻole maopopo i ka hoʻomaikaʻi ʻana i ka hana. pono a me ka waiwai waiwai.
ʻO nā seramika silikoni"e kū"
I kēia manawa, ua hele mai nā kānaka me kahi mea me ka hana ʻoi aku ka maikaʻi e hoʻololi i kekahi mau mea quartz-silicon carbide ceramics.
ʻO ka silikon carbide ceramics ka ikaika mechanical maikaʻi, thermal stability, high temperature resistance, oxidation resistance, thermal shock resistance and chemical corrosion resistance, a ua hoʻohana nui ʻia i nā māla wela e like me ka metallurgy, machinery, hou ikehu, a me nā mea kūkulu hale a me nā kemika. Ua lawa nō hoʻi kāna hana no ka laha ʻana o nā pūnaewele TOPcon i ka hana photovoltaic, LPCVD (ka haʻahaʻa haʻahaʻa chemical vapor deposition), PECVD (plasma chemical vapor deposition) a me nā loulou kaʻina hana wela.
Kākoʻo moku kākika silikona LPCVD a me ke kākoʻo waʻa kākika silika i hoʻonui ʻia
Ke hoʻohālikelike ʻia me nā mea quartz kuʻuna, nā kākoʻo waʻa, nā waʻa, a me nā huahana tube i hana ʻia me ka silicon carbide ceramic material i ʻoi aku ka ikaika, ʻoi aku ka maikaʻi o ka thermal stability, ʻaʻohe deformation i nā wela kiʻekiʻe, a me ke ola o ka ʻoi aku ma mua o 5 mau manawa o nā mea quartz. e hoʻemi i ke kumukūʻai o ka hoʻohana ʻana a me ka nalowale o ka ikehu ma muli o ka mālama ʻana a me ka manawa haʻahaʻa. ʻIke ʻia ka pōmaikaʻi o ke kumukūʻai, a ākea ke kumu o nā mea maka.
Ma waena o lākou, ʻo ka reaction sintered silicon carbide (RBSiC) he haʻahaʻa sintering haʻahaʻa, haʻahaʻa ke kumu kūʻai, kiʻekiʻe mea densification, a aneane ʻaʻohe leo shrinkage i ka wā o ka sintering. He kūpono loa ia no ka hoʻomākaukau ʻana i nā ʻāpana hana nui a paʻakikī. No laila, ʻoi aku ka maikaʻi no ka hana ʻana i nā huahana nui a paʻakikī e like me ke kākoʻo waʻa, nā waʻa, nā hoe cantilever, nā paipu umu, etc.
Nā waʻa wafer silikonikaloaʻa nō hoʻi nā manaʻolana hoʻomohala nui i ka wā e hiki mai ana. Ma waho o ke kaʻina hana LPCVD a i ʻole ke kaʻina hana hoʻonui boron, ʻoi aku ka haʻahaʻa o ke ola o ka waʻa quartz, a ʻaʻole kūlike ka koena hoʻonui wela o ka mea quartz me ka mea o ka mea carbide silicon. No laila, maʻalahi ka loaʻa ʻana o nā deviations i ke kaʻina o ka hoʻohālikelike ʻana me ka mea paʻa waʻa silicon carbide i ka wela kiʻekiʻe, e alakaʻi ana i ke kūlana o ka lulu ʻana i ka waʻa a i ʻole ka haki ʻana i ka moku. Hoʻohana ka waʻa silicon carbide i ke ala kaʻina o ka ʻāpana ʻāpana a me ka hana holoʻokoʻa. He kiʻekiʻe kona ʻano a me kona kūlana hoʻomanawanui, a ʻoi aku ka maikaʻi o ka hui pū ʻana me ka mea paʻa moku carbide silicon. Eia kekahi, ʻoi aku ka ikaika kiʻekiʻe o ka carbide silicon, a ʻoi aku ka liʻiliʻi o ka moku ma muli o ka hui ʻana o ke kanaka ma mua o ka moku quartz.
Waʻa wafer silikonika
ʻO ka pahu kapuahi ka mea hoʻoili wela nui o ka umu ahi, kahi hana i ka sila a me ka hoʻoili wela like. Ke hoʻohālikelike ʻia me nā paipu kapuahi quartz, ʻoi aku ka maikaʻi o ka conductivity thermal carbide, ka hoʻomehana ʻana, a me ke kūpaʻa wela maikaʻi, a ʻoi aku ko lākou ola ma mua o 5 mau manawa o nā paipu quartz.
Hōʻuluʻulu manaʻo
Ma keʻano laulā, inā ma ke ʻano o ka hana huahana a i ʻole ke kumu kūʻai o ka hoʻohana ʻana, ʻoi aku ka maikaʻi o nā mea hana silicon carbide ceramic ma mua o nā mea quartz i kekahi mau ʻano o ke kahua o ka lā. ʻO ka hoʻohana ʻana i nā mea seramika silicon carbide i ka ʻoihana photovoltaic ua kōkua nui i nā hui photovoltaic e hōʻemi i ke kumukūʻai hoʻopukapuka o nā mea kōkua a hoʻomaikaʻi i ka maikaʻi o ka huahana a me ka hoʻokūkū. I ka wā e hiki mai ana, me ka hoʻohana nui ʻana o nā paipu kapuahi silicon carbide nui, kiʻekiʻe-maʻemaʻe kiʻekiʻe kiʻekiʻe silicon carbide waʻa a me ka waʻa kākoʻo a me ka ho'ēmi mau o nā kumukūʻai, e lilo ka noi o ka silicon carbide ceramic mea ma ke kula o photovoltaic cell. he kumu nui i ka hoʻomaikaʻi ʻana i ka hoʻololi ʻana o ka ikehu māmā a me ka hoʻohaʻahaʻa ʻana i nā kumukūʻai ʻoihana ma ke kahua o ka hana mana photovoltaic, a he hopena koʻikoʻi i ka hoʻomohala ʻana o ikehu hou photovoltaic.
