Ke hoʻomau nei ka poʻe ʻepekema i ke koinā panela lāe oi aku ka pono, a aia kekahi mooolelo hou e hoike mai: A hou solar cell loaa ka pono o 39.5 pakeneka ma lalo o 1-lā global kukui kūlana.
ʻO ka hōʻailona 1-lā he ala maʻamau wale nō ia e ana i ka nui o ka lā, i kēia manawa kokoke i 40% o ka radiation hiki ke hoʻololi ʻia i uila. ʻO ka moʻolelo mua no kēia ʻanopanel solarhe 39.2% ka pono.
ʻOi aku ka nui o nā ʻano o nā pūnaewele lā a puni ma mua o kou manaʻo. ʻO ke ʻano i hoʻohana ʻia ma ʻaneʻi he triple-junction III-V tandem solar cell, i hoʻohana mau ʻia i nā satelite a me nā mokulele, ʻoiai he nui ko lākou mana ma ka lepo paʻa.
"ʻOi aku ka maikaʻi a me ka maʻalahi o nā pūnaewele hou i ka hoʻolālā ʻana, a hiki ke hoʻohana ʻia no nā ʻano noiʻi hou, e like me nā noi kaohi nui a i ʻole nā noi wahi haʻahaʻa haʻahaʻa," wahi a Myles Steiner o ka National Renewable Energy Laboratory..”NREL) ma Colorado.
Ma keʻano o ka pono o ka cell solar, he mea nui ka "triple junction" o ka hoohalike. Hoʻopiliʻia kēlā me kēia puʻupuʻu ma kahi kiko'ī o ka laulā o ka lā,ʻo ia hoʻi ka emiʻana o ka māmā a me ka hoʻohanaʻoleʻia.
Hoʻonui hou ʻia ka maikaʻi ma ka hoʻohana ʻana i ka ʻenehana i kapa ʻia ʻo "quantum well". ka liʻiliʻi o ka ikehu e pono ai e hoʻoulu i nā electrons a ʻae i ke kahe o kēia manawa.
I kēia hihia, ʻo nā hui ʻekolu he gallium indium phosphide (GaInP), gallium arsenide (GaAs) me kekahi ʻoi aku ka maikaʻi o ka luawai quantum, a me ka gallium indium arsenide (GaInAs).
"ʻO kahi kumu koʻikoʻi ʻoiai he mea maikaʻi loa ʻo GaAs a hoʻohana maʻamau ʻia i nā cell multijunction III-V, ʻaʻole ia i ka bandgap pololei no nā pūnana hui ʻekolu, ʻo ia hoʻi ke kiʻi kiʻi ma waena o nā cell ʻekolu ʻAʻole maikaʻi ke kaulike. ” wahi a NREL physicist Ryan France.
"Maʻaneʻi, ua hoʻololi mākou i ka ʻāpana band me ka hoʻohana ʻana i nā pūnāwai quantum, ʻoiai e mālama ana i ka maikaʻi o nā mea waiwai, e hiki ai i kēia hāmeʻa a me nā noi ʻē aʻe."
ʻO kekahi o nā mea hoʻomaikaʻi i hoʻohui ʻia i loko o kēia kelepona hou loa e pili ana i ka hoʻonui ʻana i ka nui o ka mālamalama i hoʻopaʻa ʻia me ka ʻole o ka nalowale o ka uila.
ʻO kēia ka hana kiʻekiʻe loa o ka lā 1 o kekahipanel solarcell on record, ʻoiai ua ʻike mākou i nā ʻoi aku ka maikaʻi mai ka ʻoi aku ka ikaika o ka radiation solar.
Ua hoʻopaʻa pū ʻia nā pūnaewele he 34.2 pakeneka ka maikaʻi o ka lewa, ʻo ia ka mea e hoʻokō ai ke hoʻohana ʻia i ka orbit. ʻO ko lākou kaumaha a me ke kūpaʻa ʻana i nā ʻāpana ikaika kiʻekiʻe e kūpono loa ia no kēia hana.
"No ka mea, ʻo kēia ka ʻoi aku ka maikaʻi loa o ka 1-sun solar cell i ka manawa e kākau ai, ua hoʻonohonoho pū kēia mau cell i kahi kūlana hou no ka hiki ke hoʻokō ʻia o nā ʻenehana photovoltaic āpau," i kākau ai nā mea noiʻi i kā lākou pepa i paʻi ʻia.
