E ai ki te whatunga whakahaere ahupūngao, i pūrongo tata nei kua whakawhanakehia e ngā kairangahau o Finnish tētahi taputapu kimi whakaahua silicon pango me te whai huatanga matūriki o waho o te 130%, koinei te wā tuatahi ka nui ake te whai huatanga o ngā taputapu photovoltaic i te rohe ariā o te 100%, e matapaetia ana ka tino whakapai ake i te whai huatanga o ngā taputapu kimi whakaahua-hiko, ā, he whānuitia te whakamahinga o ēnei taputapu i roto i ngā motuka, waea pūkoro, mataaratanga atamai me ngā taputapu hauora.
He pūoko te pūoko whakaahua e taea ai te ine i te mārama, i tētahi atu pūngao hikohiko rānei, te huri i ngā photon hei iahiko hiko, ā, ko ngā photon kua mimitihia ka hanga i ngā takirua irahiko-pōhatu. Kei roto i te pūoko whakaahua te photodiode me te phototransistor, me ētahi atu. Ka whakamahia te pai o te matū hei tautuhi i te ōrau o ngā photon i whiwhihia e tētahi taputapu pēnei i te pūoko whakaahua ki roto i te takirua irahiko-pōhatu, arā, ko te pai o te matū he ōrite ki te maha o ngā irahiko whakaahua kua wehea ki te maha o ngā photon taunga.
Ina puta he irahiko mai i te photon taunga mai ki tētahi ara iahiko o waho, ko te whai huatanga matūriki o waho o te taputapu he 100% (i whakaarohia i mua koinei te rohe ariā). I roto i te rangahau hou, ko te whai huatanga o te taputapu whakaahua silicon pango he 130 ōrau, ko te tikanga ka puta he irahiko mai i te photon taunga mai i te 1.3 pea.
E ai ki ngā kairangahau o Te Whare Wānanga o Aalto, ko te patu ngaro kei muri i tēnei putanga nui ko te tukanga whakarea o ngā kaikawe utu e puta ana i roto i te hanganga nano ahurei o te taputapu whakaahua silicon pango, e whakaohohia ana e ngā photon pūngao-teitei. I mua, kāore i taea e ngā kaipūtaiao te tirotiro i te āhuatanga i roto i ngā taputapu tūturu nā te mea i whakaitihia te maha o ngā irahiko i kohia e te noho mai o ngā mate hiko me te whatu. "Kāore he whakakotahitanga anō, kāore hoki he mate whakaata o ā mātou taputapu hanganga nano, nō reira ka taea e mātou te kohikohi i ngā kaikawe utu kua whakareatia katoa," te whakamārama a te kaiārahi rangahau a Ahorangi Hera Severn.
Kua manatokohia tēnei whai huatanga e te Institute of Physical Technology of the German National Metrology Society (PTB), te ratonga ine tino tika me te pono i Ūropi.
E ai ki ngā kairangahau, ko te whai huatanga o tēnei rekoata ka taea e ngā kaipūtaiao te whakapai ake i te mahi a ngā taputapu kimi whakaahua-hiko.
"Kua nui te aro ki ā mātou taputapu kite, inā koa i roto i ngā wāhanga o te hangarau koiora me te aroturuki i ngā tukanga ahumahi," te kī a Tākuta Mikko Juntuna, te Tumu Whakarae o ElfysInc, he kamupene nō Te Whare Wānanga o Aalto. E ai ki ngā pūrongo kua tīmata rātou ki te hanga i aua taputapu kite mō te whakamahinga arumoni.
