He makahiki piha ʻo 2022 i nā pilikia no ka honua holoʻokoʻa.ʻAʻole i pau loa ka maʻi maʻi New Champions, a ua hahai ka pilikia ma Rusia a me Ukraine.I kēia kūlana paʻakikī a paʻakikī hoʻi, ke ulu nei ka noi no ka palekana o ka ikehu o nā ʻāina āpau o ka honua i kēlā me kēia lā.
I mea e pale aku ai i ka ulu ʻana o ka ikehu i ka wā e hiki mai ana, ua huki ka ʻoihana photovoltaic i ka ulu pahū.I ka manawa like, ke hoʻoikaika ikaika nei nā ʻoihana like ʻole i ka hanauna hou o ka ʻenehana cell photovoltaic e hopu i ka mākeke kiʻekiʻe.
Ma mua o ka nānā ʻana i ke ala o ka ʻenehana kelepona, pono mākou e hoʻomaopopo i ke kumu o ka hana mana photovoltaic.
ʻO ka hana mana Photovoltaic kahi ʻenehana e hoʻohana ana i ka hopena photovoltaic o ka interface semiconductor e hoʻololi pololei i ka ikehu māmā i ka ikehu uila.ʻO kāna kumu nui ka hopena photoelectric o semiconductor: ke ʻano o ka ʻokoʻa like ʻole ma waena o heterogeneous semiconductor a i ʻole nā ʻāpana like ʻole o ka semiconductor a me ka hoʻopaʻa metala i hoʻokumu ʻia e ka mālamalama.
Ke ʻālohilohi nā kiʻi kiʻi ma luna o ka metala, hiki ke komo i ka ikehu e kahi electron i loko o ka metala, a hiki i ka electron ke pakele mai ka ʻili metala a lilo i photoelectron.Loaʻa i nā ʻātoma silikona ʻehā mau electrons waho.Inā hoʻokomo ʻia nā ʻātoma phosphorus me ʻelima mau electrons waho i loko o nā mea silika, hiki ke hana ʻia nā wafers silicon N-type;Inā hoʻokomo ʻia nā ʻātoma boron me ʻekolu mau electrons waho i loko o ka mea silikona, hiki ke hoʻokumu ʻia kahi chip silicon type P."
Ua hoʻomākaukau ʻia ka chip pālolo ʻano P a me ka chip silicon type N e ka chip silicon type P a me ka chip silicon type N ma o nā ʻenehana like ʻole.
Ma mua o ka makahiki 2015, ua noho nā pahu pahu pahu alumini (BSF) kokoke i ka mākeke holoʻokoʻa.
ʻO ka pahu pahu pahu alumini ka ala maʻamau maʻamau: ma hope o ka hoʻomākaukau ʻana i ka hui PN o ke kiʻi kiʻi kiʻi ʻoniʻoni kristal, waiho ʻia kahi ʻāpana kiʻi alumini ma ka ʻaoʻao backlight o ka chip silicon no ka hoʻomākaukau ʻana i ka P + layer, pēlā e hana ai i kahi kahua hope alumini. , e hana ana i ke kahua uila hui kiʻekiʻe a me ka haʻahaʻa, a me ka hoʻomaikaʻi ʻana i ka uila kaapuni hāmama.
Eia nō naʻe, ʻilihune ka pale ʻana i ka irradiation o ka pahu pahu alumini.I ka manawa like, ʻo 20% wale nō kona palena hoʻololi, a ʻoi aku ka haʻahaʻa o ka hoʻololi maoli.ʻOiai i kēia mau makahiki i hala iho nei, ua hoʻomaikaʻi ka ʻoihana i ke kaʻina hana o ka pā BSF, akā ma muli o kāna mau palena ʻokoʻa, ʻaʻole nui ka hoʻomaikaʻi ʻana, ʻo ia hoʻi ke kumu i manaʻo ʻia e hoʻololi ʻia.
Ma hope o ka makahiki 2015, ua piʻi wikiwiki ka māhele mākeke o nā pahu pākaukau Perc.
Hoʻomaikaʻi ʻia ka pahu pākahi Perc mai ka pahu pahu pahu alumini maʻamau.Ma ka hoʻopili ʻana i kahi papa passivation dielectric ma ke kua o ka pākaukau, ua hoʻemi maikaʻi ʻia ka poho photoelectric a hoʻomaikaʻi ʻia ka hoʻololi ʻana.
ʻO ka makahiki 2015 ka makahiki mua o ka hoʻololi ʻenehana o nā cell photovoltaic.I kēia makahiki, ua hoʻopau ʻia ka hoʻolaha ʻana o ka ʻenehana Perc, a ua ʻoi aku ka maikaʻi o ka hana nui ʻana o nā pila ma mua o ka palena o ka hoʻololi ʻana i ka pono o nā pahu pahu alumini ma hope o 20% no ka manawa mua, e komo ana i ke kahua hana nui.
Hōʻike ka hana hoʻololi i nā pono waiwai kiʻekiʻe.Ma hope o ka hana nui ʻana, ua piʻi wikiwiki ka māhele mākeke o Perc pākīkī a komo i kahi pae o ka ulu wikiwiki.Ua piʻi ka māhele mākeke mai 10.0% i 2016 a i 91.2% i 2021. I kēia manawa, ua lilo ia i kumu nui o ka ʻenehana hoʻomākaukau ʻana i ka pākaukau ma ka mākeke.
I ka ʻōlelo o ka hoʻololi ʻana, ʻo ka awelika o ka hoʻololi ʻana o ka hana nui o nā pākahi Perc i 2021 e hiki i 23.1%, 0.3% kiʻekiʻe ma mua o 2020.
Mai ka hiʻohiʻona o ka theoretical palena pono, e like me ka helu ana o Solar Energy Research Institute, ka theoretical palena pono o P-type monocrystalline silicon Perc pākaukau he 24.5%, i kokoke loa i ka theoretical palena pono i keia manawa, a ua kaupalena 'ia. lumi no ka hoʻomaikaʻi ʻana i ka wā e hiki mai ana.
Akā i kēia manawa, ʻo Perc ka ʻenehana chip pākaukau nui loa.Wahi a CPI, ma ka 2022, hiki i ka 23.3% ka nui o ka hana ʻana o nā pākahi PERC, ʻoi aku ka nui o ka hana ma mua o 80%, a ʻo ka māhele mākeke e pae mua.
Loaʻa nā pōmaikaʻi o ka pākaukau N-type o kēia manawa i ka hoʻololi ʻana a e lilo ia i kumu nui o ka hanauna e hiki mai ana.
Ua hoʻokomo mua ʻia ka loina hana o ka puʻupuʻu pākahi N-type.ʻAʻohe ʻokoʻa koʻikoʻi ma waena o ke kumu manaʻo o nā ʻano pākahi ʻelua.Eia nō naʻe, ma muli o ka ʻokoʻa o ka ʻenehana o ka hoʻolaha ʻana i ka B a me P i ke kenekulia, ke kū nei lākou i nā pilikia like ʻole a me nā kūlana hoʻomohala i ka hana ʻoihana.
ʻO ke kaʻina hana hoʻomākaukau o ka pā ʻano P he mea maʻalahi a haʻahaʻa ke kumu kūʻai, akā aia kekahi ʻokoʻa ma waena o ka pā ʻano P a me ka pā ʻano N ma ke ʻano o ka hoʻololi ʻana.ʻOi aku ka paʻakikī o ke kaʻina hana o ke ʻano ʻano N, akā loaʻa iā ia nā pōmaikaʻi o ka hoʻololi kiʻekiʻe o ka hoʻololi ʻana, ʻaʻohe attenuation māmā, a me ka hopena māmā nāwaliwali.
