ʻO ka panel solar kekahi o nā mea nui i ka ʻōnaehana hana mana o ka lā.ʻO kāna hana ʻo ia ka hoʻololi ʻana i ka ikehu o ka lā i ka ikehu uila, a laila hoʻopuka i ka uila DC e mālama i loko o ka pā.ʻO kāna helu hoʻololi a me ke ola lawelawe he mau mea koʻikoʻi ia e hoʻoholo ai inā he waiwai hoʻohana ka solar cell.
Hoʻopili ʻia nā pūnaewele lā me ka pono kiʻekiʻe (ʻoi aku ma mua o 21%) monocrystalline silicon solar cell e hōʻoia i ka lawa o ka mana i hana ʻia e nā panela lā.Hana ʻia ke aniani me ke aniani suede haʻahaʻa haʻahaʻa haʻahaʻa (ʻike ʻia ʻo ke aniani keʻokeʻo), nona ka transmittance o ʻoi aku ma mua o 91% i loko o ka hawewe lōʻihi o ka pane spectral cell solar, a he kiʻekiʻe reflectivity no ke kukui infrared ʻoi aku ma mua o 1200 nm.I ka manawa like, hiki i ke aniani ke pale i ka radiation o ke kukui ultraviolet solar me ka hoʻohaʻahaʻa ʻole i ka transmittance.Hoʻohana ʻo EVA i kahi kiʻiʻoniʻoni EVA kiʻekiʻe me ka mānoanoa o 0.78mm i hoʻohui ʻia me ka anti ultraviolet agent, antioxidant and curing agent ma ke ʻano he sealing agent no nā cell solar a me ka mea hoʻohui i waena o ke aniani a me ka TPT, he kiʻekiʻe ka transmittance a me ka anti-aging.
ʻO ka uhi hope o ka TPT solar cell - fluoroplastic film he keʻokeʻo, e hōʻike ana i ka lā o ka lā, no laila ua hoʻomaikaʻi iki ka pono o ka module.Ma muli o kona emissivity infrared kiʻekiʻe, hiki iā ia ke hoʻemi i ka mahana hana o ka module, a he mea kūpono hoʻi i ka hoʻomaikaʻi ʻana i ka pono o ka module.ʻO ka pahu alumini alumini i hoʻohana ʻia no ke kiʻi he ikaika kiʻekiʻe a me ke kūpaʻa hopena mechanical ikaika.ʻO ia hoʻi ka ʻāpana waiwai loa o ka ʻōnaehana hana mana o ka lā.ʻO kāna hana, ʻo ia ka hoʻololi ʻana i ka mana pāhawewe lā i ka ikehu uila, a i ʻole e hoʻouna iā ia i ka pā hale mālama no ka mālama ʻana, a i ʻole e paipai i ka hana ukana.
Ku'ina Hana o Panela Solar
He mea semiconductor ka panel solar e hiki ke hoʻololi pololei i ka ikehu māmā i ikehu uila.Hoʻokumu ʻia kona ʻano kumu me ka hui semiconductor PN.ʻO ka lawe ʻana i ka mea maʻamau silicon PN solar cell ma ke ʻano he laʻana, ʻo ka hoʻololi ʻana o ka ikehu māmā i ka ikehu uila ke kūkākūkā nui ʻia.
E like me kā mākou e ʻike ai, ʻo nā mea i loaʻa ka nui o nā ʻāpana i hoʻopiʻi manuahi a maʻalahi hoʻi e hoʻokele i kēia manawa ua kapa ʻia ʻo ia he conductors.ʻO ka maʻamau, ʻo nā metala nā mea hoʻokele.No ka laʻana, ʻo ka conductivity o ke keleawe ma kahi o 106/(Ω. cm).Inā hoʻohana ʻia ka volta o 1V i ʻelua mau ʻili like o ka pahu keleawe 1cm x 1cm x 1cm, e kahe ana ke au o 106A ma waena o nā ʻili ʻelua.Ma ka ʻaoʻao ʻē aʻe he mau mea paʻakikī loa e alakaʻi i kēia manawa, i kapa ʻia nā insulators, e like me ka ceramics, mica, grease, rubber, etc. .He conductivity ka semiconductor ma waena o ka conductor a me ka insulator.He 10-4~104/(Ω. cm) kona conductivity.Hiki i ka semiconductor ke hoʻololi i kona conductivity i ka pae i luna ma o ka hoʻohui ʻana i kahi liʻiliʻi o nā haumia.E piʻi nui ka conductivity o semiconductor maʻemaʻe me ka piʻi ʻana o ka mahana.
Hiki i nā Semiconductors ke lilo i mau mea, e like me ke silicon (Si), germanium (Ge), selenium (Se), etc;Hiki iā ia ke lilo i pūhui, e like me ka cadmium sulfide (Cds), gallium arsenide (GaAs), etc;Hiki iā ia ke lilo i huila, e like me Ga, AL1~XAs, kahi x he helu ma waena o 0 a me 1. Hiki ke wehewehe ʻia ka nui o nā waiwai uila o nā semiconductor e ke kumu hoʻohālike maʻalahi.He 14 ka helu atomika o ke kilika, no laila, aia he 14 mau electrons ma waho o ka nucleus atom.Ma waena o lākou, ua hoʻopaʻa paʻa ʻia nā electrons 10 i ka ʻaoʻao i loko e ka nucleus atomic, ʻoiai ʻo 4 electrons i ka ʻaoʻao o waho e liʻiliʻi i ka nakinaki ʻia e ka atomic nucleus.Inā lawa ka ikehu, hiki ke hoʻokaʻawale ʻia mai ka nucleus atomic a lilo i electrons manuahi, e waiho ana i kahi puka ma ke kūlana kumu i ka manawa like.Hoʻopiʻi maikaʻi ʻia nā Electrons a hoʻopiʻi maikaʻi nā puka.Ua kapa ʻia nā electrons ʻehā i ka papa waho o ka nucleus silicon.
I loko o ke aniani silika, aia nā ʻātoma pili ʻehā a puni kēlā me kēia ʻātoma a me ʻelua electron valence me kēlā me kēia ʻātoma pili, e hana ana i ka pūpū 8-atom paʻa.Lawe ia i ka ikehu 1.12eV no ka hoʻokaʻawale ʻana i kahi electron mai ka ʻātoma silika, i kapa ʻia ʻo ke āwaha huila silika.ʻO nā electrons i hoʻokaʻawale ʻia he mau electrons conduction manuahi, hiki ke neʻe manuahi a hoʻouna i kēia manawa.Ke pakele ka electron mai kahi atom, waiho ia i kahi hakahaka, i kapa ʻia he puka.Hiki i nā electrons mai nā ʻātoma pili ke hoʻopiha i ka lua, e neʻe ai ka puka mai kahi kūlana a i kahi hou, no laila e hana ai i kahi au.ʻO ke au i hana ʻia e ke kahe ʻana o nā electrons ua like ia me ka mea i hana ʻia i ka wā e neʻe ai ka lua i hoʻopiʻi maikaʻi ʻia i ka ʻaoʻao ʻē aʻe.
