I ka ʻoihana photovoltaic, ua makemake nui ka perovskite i nā makahiki i hala iho nei.ʻO ke kumu i puka mai ai ma ke ʻano he "punahele" ma ke kahua o nā pūnaewele lā ma muli o kona kūlana kūʻokoʻa.ʻO ka calcium titanium ore ka nui o nā waiwai photovoltaic maikaʻi loa, ke kaʻina hana hoʻomākaukau maʻalahi, a me kahi ākea o nā mea maka a me nā ʻike nui.Eia kekahi, hiki ke hoʻohana ʻia ka perovskite i nā mea kanu mana honua, ka mokulele, ke kūkulu ʻana, nā mea hana mana hiki ke hoʻohana ʻia a me nā māla ʻē aʻe.
Ma Malaki 21, ua noi ʻo Ningde Times no ka patent o "calcium titanite solar cell a me kāna ʻano hoʻomākaukau a me ka mana mana".I nā makahiki i hala iho nei, me ke kākoʻo ʻana o nā kulekele kūloko a me nā ana, ʻo ka ʻoihana calcium-titanium ore, i hōʻike ʻia e ka calcium-titanium ore solar cell, ua holomua nui.No laila he aha ka perovskite?Pehea ka hana ʻana o ka perovskite?He aha nā pilikia e kū nei?Nīnauele ʻo Science and Technology Daily i nā poʻe loea kūpono.
ʻAʻole ka calcium a me ka titanium ka perovskite.
ʻO nā mea i kapa ʻia ʻo perovskites ʻaʻole ia he calcium a i ʻole titanium, akā he huaʻōlelo maʻamau no ka papa o nā "ceramic oxides" me ke ʻano aniani like, me ka molecular formula ABX3.ʻO A ke kū nei no ka "radius cation nui", B no ka "cation metal" a me X no ka "anion halogen".ʻO A ke kū nei no ka "radius cation nui", ʻo B no ka "metal cation" a ʻo X no ka "halogen anion".Hiki i kēia mau ion ʻekolu ke hōʻike i nā waiwai kino kupaianaha ma o ka hoʻonohonoho ʻana i nā mea like ʻole a i ʻole ka hoʻoponopono ʻana i ka mamao ma waena o lākou, me ka ʻaʻole i kaupalena ʻia i ka insulation, ferroelectricity, antiferromagnetism, giant magnetic effect, etc.
"E like me ka haku mele ʻana o ka mea, hiki ke hoʻokaʻawale ʻia nā perovskites i ʻekolu mau ʻāpana: complex metal oxide perovskites, organic hybrid perovskites, a me inorganic halogenated perovskites."Ua hōʻike ʻo Luo Jingshan, he kumu aʻo ma ke kula ʻo Nankai University's Electronic Information and Optical Engineering, ʻo nā titanites calcium i hoʻohana ʻia i kēia manawa i nā photovoltaics ʻo ia nā mea ʻelua.
Hiki ke hoʻohana ʻia ka perovskite ma nā kula he nui e like me nā mea kanu mana honua, aerospace, kūkulu, a me nā mea hana mana hiki ke hoʻohana.I waena o lākou, ʻo ke kahua photovoltaic ka wahi noi nui o perovskite.Hoʻolālā maikaʻi ʻia nā hale calcium titanite a loaʻa ka hana photovoltaic maikaʻi loa, ʻo ia kahi kuhikuhi noiʻi kaulana i ke kula photovoltaic i nā makahiki i hala iho nei.
Ke wikiwiki nei ka ʻoihana o perovskite, a ke hoʻokūkū nei nā ʻoihana kūloko no ka hoʻolālā.Ua hōʻike ʻia ʻo nā ʻāpana mua 5,000 o ka calcium titanium ore modules i hoʻouna ʻia mai Hangzhou Fina Photoelectric Technology Co., Ltd;ʻO Renshuo Photovoltaic (Suzhou) Co., Ltd. ke hoʻokē ʻai nei i ke kūkulu ʻana i ka laina pilo pilo laminated nui loa o ka honua he 150 MW piha calcium titanium ore;Kunshan GCL Photoelectric Materials Co. Ltd. 150 MW calcium-titanium ore photovoltaic module production line ua hoʻopau ʻia a hoʻokomo ʻia i ka hana ma Dekemaba 2022, a hiki i ka waiwai hoʻopuka makahiki ke hiki i 300 miliona yuan ma hope o ka hiki ʻana i ka hana.
Loaʻa nā pōmaikaʻi o ka calcium titanium ore i ka ʻoihana photovoltaic
I ka ʻoihana photovoltaic, ua makemake nui ka perovskite i nā makahiki i hala iho nei.ʻO ke kumu i puka mai ai ma ke ʻano he "punahele" ma ke kahua o nā pūnaewele lā ma muli o kāna mau kūlana kūʻokoʻa.
ʻO ka mea mua, he nui nā waiwai optoelectronic perovskite, e like me ka adjustable band gap, high absorption coefficient, haʻahaʻa exciton hoʻopaʻa i ka ikehu, kiʻekiʻe ka lawe kaʻa, hoʻomanawanui defect kiʻekiʻe, etc.;ʻO ka lua, he maʻalahi ke kaʻina hana hoʻomākaukau o ka perovskite a hiki ke loaʻa i ka translucency, ultra-lightness, ultra-thinness, flexibility, etc. ʻO ka mea hope loa, loaʻa nui nā perovskite maka waiwai a nui.Ua hoʻolauna ʻo Luo Jingshan.A ʻo ka hoʻomākaukau ʻana i ka perovskite e pono ai ka hoʻomaʻemaʻe haʻahaʻa o nā mea maka.
I kēia manawa, hoʻohana ke kahua PV i ka helu nui o nā pūnaewele lā i hoʻokumu ʻia i ke kilika, hiki ke hoʻokaʻawale ʻia i loko o ka silikon monocrystalline, polycrystalline silicon, a me ka amorphous silicon solar cell.ʻO ka theoretical photoelectric hoʻololi pole o crystalline silicon cell is 29.4%, a hiki i ke keʻena hoʻokolohua o kēia manawa ke hiki i kahi kiʻekiʻe o 26.7%, kahi kokoke loa i ke kaupaku o ka hoʻololi ʻana;ʻike ʻia e liʻiliʻi a liʻiliʻi hoʻi ka loaʻa ʻana o ka marginal o ka holomua ʻenehana.ʻO ka hoʻohālikelike ʻana, ʻoi aku ka kiʻekiʻe o ka hoʻololi ʻana o ka photovoltaic o nā cell perovskite he 33%, a inā e hoʻopaʻa ʻia nā ʻelua perovskite i luna a i lalo, hiki i ka 45%.
Ma waho aʻe o ka "kūpono", ʻo kekahi kumu koʻikoʻi ʻo "koki".No ka laʻana, ʻo ke kumu e hiki ʻole ai ke iho i lalo ke kumu kūʻai o ka hanauna mua o nā pā kiʻi ʻoniʻoni ʻoniʻoni ʻo ia ka liʻiliʻi o nā mālama o cadmium a me gallium, he mau mea laʻa ʻole ma ka honua, a ʻo ka hopena, ʻoi aku ka hoʻomohala ʻana o ka ʻoihana. ʻo ia, ʻoi aku ka nui o ka koi, ʻoi aku ka kiʻekiʻe o ke kumukūʻai hana, a ʻaʻole hiki ke lilo i huahana mainstream.Hāʻawi ʻia nā mea maka o ka perovskite i ka nui o ka honua, a ʻoi aku ka liʻiliʻi o ke kumukūʻai.
Eia kekahi,ʻo ka mānoanoa o ka calcium-titanium ore coating no ka calcium-titanium ore batteries he mau haneli nanometer wale nō, e pili ana i ka 1 / 500th o nā wafers silicon,ʻo ia hoʻi he mea liʻiliʻi loa ka noi no ka mea.ʻO kahi laʻana, ʻo ka noi honua i kēia manawa no nā mea silika no nā cell silicon crystalline ma kahi o 500,000 tons i kēlā me kēia makahiki, a inā e hoʻololi ʻia lākou āpau me nā cell perovskite, ma kahi o 1,000 tons perovskite wale nō e pono ai.
Ma ke ʻano o ka hana ʻana i nā kumukūʻai, pono ke hoʻomaʻemaʻe silika i ka 99.9999%, no laila pono e hoʻomaʻamaʻa ʻia ke silika i 1400 degere Celsius, hoʻoheheʻe ʻia i loko o ka wai, huki ʻia i loko o nā koʻokoʻo a me nā ʻāpana, a laila hoʻohui ʻia i loko o nā keʻena, me ʻehā mau hale hana a me ʻelua. i ʻekolu lā ma waena, a ʻoi aku ka nui o ka ikehu.I ka hoʻokaʻawale ʻana, no ka hana ʻana i nā cell perovskite, pono wale nō e hoʻopili i ka wai kumu perovskite i ka substrate a laila kali no ka crystallization.ʻO ke kaʻina holoʻokoʻa e pili ana i ke aniani, ke kiʻi ʻoniʻoni, ka perovskite a me nā mea kemika, a hiki ke hoʻopau ʻia i loko o ka hale hana hoʻokahi, a ʻo ke kaʻina holoʻokoʻa he 45 mau minuke wale nō.
"ʻO nā cell solar i hoʻomākaukau ʻia mai ka perovskite he maikaʻi ka hoʻololi photoelectric maikaʻi loa, ua hiki i ka 25.7% i kēia manawa, a hiki ke hoʻololi i nā cell solar-based ma mua i lilo i kumu kūʻai nui."wahi a Luo Jingshan.
ʻEkolu mau pilikia nui e pono e hoʻoholo no ka hoʻoikaika ʻana i ka ʻoihana
I ka holomua ʻana i ka hana ʻana o ka chalcosite, pono nā kānaka e hoʻoponopono i nā pilikia 3, ʻo ia hoʻi ka paʻa lōʻihi o ka chalcosite, ka hoʻomākaukau ʻana i nā wahi nui a me ka ʻona o ke kēpau.
ʻO ka mea mua, paʻakikī loa ka perovskite i ke kaiapuni, a ʻo nā mea e like me ka mahana, ka haʻahaʻa, ka māmā, a me ka ukana kaapuni hiki ke alakaʻi i ka decomposition o ka perovskite a me ka hoʻemi ʻana o ka pono cell.I kēia manawa, ʻaʻole i kūpono ka hapa nui o nā modula perovskite i ka IEC 61215 maʻamau no nā huahana photovoltaic, ʻaʻole hoʻi i hiki i ka 10-20 mau makahiki o ke ola o nā cell solar silicon, no laila ʻaʻole maikaʻi ke kumu kūʻai o ka perovskite ma ke kahua photovoltaic kuʻuna.Eia kekahi, he paʻakikī loa ka mīkini hoʻohaʻahaʻa o ka perovskite a me kāna mau mea hana, a ʻaʻohe ʻike maopopo loa o ke kaʻina hana ma ke kula, ʻaʻole hoʻi he maʻamau quantitative i hui ʻia, kahi e hōʻino ai i ka noiʻi paʻa.
ʻO kekahi pilikia nui ʻo ia ka hoʻomākaukau ʻana iā lākou ma ke ʻano nui.I kēia manawa, i ka wā e hana ʻia ai nā haʻawina hoʻomaikaʻi ʻana i nā hāmeʻa i loko o ka hale hana, ʻoi aku ka liʻiliʻi o ka ʻāpana māmā o nā mea i hoʻohana ʻia ma mua o 1 cm2, a i ka wā e hiki mai ana i ke kahua noiʻi kālepa o nā ʻāpana nui, pono e hoʻomaikaʻi ʻia nā ʻano hana hoʻomākaukau. a pani ʻia paha.ʻO nā ala nui e pili ana i kēia manawa no ka hoʻomākaukau ʻana i nā kiʻiʻoniʻoni perovskite ākea nui ke ʻano hoʻonā a me ke ʻano o ka hoʻoheheʻe ʻana i ka vacuum.Ma ke kaʻina hana hoʻonā, ka manaʻo a me ka ratio o ka hopena precursor, ke ʻano o ka solvent, a me ka manawa mālama i ka hopena nui i ka maikaʻi o nā kiʻi perovskite.Hoʻomākaukau ke ʻano hoʻoheheʻe ʻana i ka maikaʻi maikaʻi a me ka hoʻopaʻa ʻia ʻana o nā kiʻi perovskite, akā paʻakikī hou ka hoʻokō maikaʻi ʻana ma waena o nā precursors a me nā substrates.Eia kekahi, no ka mea, pono e hoʻomākaukau ʻia ka papa lawe ukana o ka mīkini perovskite ma kahi nui, pono e hoʻokumu ʻia kahi laina hana me ka hoʻomau mau ʻana o kēlā me kēia papa i ka hana ʻoihana.Ma ke ʻano holoʻokoʻa, pono e hoʻonui hou ʻia ke kaʻina hana o ka hoʻomākaukau ʻana i nā kiʻi ʻoniʻoni lahilahi perovskite.
ʻO ka hope, ʻo ka ʻawaʻawa o ke kēpau kekahi mea e hopohopo nei.I ka wā kahiko o nā polokalamu perovskite kiʻekiʻe o kēia manawa, e hoʻoheheʻe ʻia ka perovskite e hana i nā ion alakaʻi manuahi a me nā monomers alakaʻi, e pōʻino ai ke olakino ke komo lākou i ke kino kanaka.
