Ko te whakapai ake i te whai huatanga o te mōkihi me te whakawhānui i te kaha hanga he mahi tahi ki te whakaiti i te utu o ngā mōkihi rā whakarewa halide chalcogenide/silicon stapped. I tohu ngā kairangahau o te Tari Pūngao Whakahou ā-Motu o te US Department of Energy (US Department of Energy's National Renewable Energy Laboratory, NREL) e whai ake nei: ka taea e ia pānga utu te whai i tētahi mahi ōrite, i runga i te kaha o te kaihanga ki te whakawhānui me te whakapai ake i te mahi o te mōkihi.
Ko te nuinga o ngā kōwae photovoltaic (PV) e hangaia ana i ēnei rā he mea hanga mai i ngā pūtau rā silicon kotahi-hononga, ā, mā te hono i te silicon me tētahi atu rauemi pūtau rā (pēnei i te halide whakarewa) hei hanga i tētahi puranga chalcogenides (MHP), ka taea e ngā kaihanga te hanga kōwae rā. Ka taea e tēnei te huri i te hihi o te rā ki te hiko atu i te silicon anake. Kei te tīmatanga tonu tēnei hangarau puranga, ā, he maha ngā kōwhiringa e rapuhia ana hei whakauru i ngā MHP, me te maha o ngā mea kāore i te mōhiotia mō te utu me te mahi. Hei whakatika i tēnei āputa, i hangaia e ngā kairangahau he tauira utu hanga e whakamahi ana i ngā taputapu o nāianei me ngā tukanga taiwhanga mekameka tuku hei whakataurite i ngā huarahi rerekē ka taea i te tauine.
I tirotirohia e ngā kairangahau ngā huarahi maha ki te hanga i ngā kōwae whakarārangi, ā, i whakaritea te aro o ngā utu hanga ki ngā rauemi i whakamahia hei hanga i aua kōwae, te maha o ngā paparanga taputapu, te utu mō te hanga i ngā taputapu, te wāhi o te wheketere, me ētahi atu āhuatanga. I kitea e rātou ko ngā āhuatanga i tino pā ki ngā utu hanga ko te nui o te mahi a te wheketere me te whai huatanga o te kōwae.
"Ko tētahi o ngā pātai e whakautua ana e tēnei pepa ko: he aha te uara o tēnei whai huatanga?" te kī a Jacob Cordell, te kaituhi matua o te pepa "Technoeconomic analysis of perovskite/silicon tandem solar modules," i whakaputaina i roto i te puka Joule. "Ko tētahi o ngā mea nui ko te pikinga 2.5% o te whai huatanga tino pai i roto i ngā kōwae ka rite te whakaiti i te utu mō ia waeine o te kaha ki te whakarea rua i te rahi o te tipu."
Mā te whakamahi i te Tauira Tātari Utu Taipitopito (DCAM) e wātea ana i te marea, i taea e ngā kairangahau te whakamātautau i ngā momo horopaki, tae atu ki te kimi i ngā tipu i ngā wāhi rerekē o te ao me ngā momo whakatenatena hanga rerekē. Mā te whakamahi i te tauira, ka taea e ngā kamupene me ngā kairangahau te whakamahi i tēnei turanga hei tirotiro i te pānga o ngā tukanga me ngā rauemi rerekē ki ngā utu. Kāore te tauira e aro ki te hua o te pūngao, ki te roanga rānei o te ora o ēnei kōwae, he wāhi rangahau hohe tonu ēnei.
I tīmata mā te tauira taketake o tētahi kaihanga e hanga ana i ngā kōwae i te 25 ōrau te pai o te mahi, me te kaha whakaputa ā-tau o te 3 gigawatts i te US, i whakaritea e ngā kairangahau te pai o te mahi me ngā hua hanga hei whakatau i te rerekētanga o te utu o ngā kōwae i te pikinga ake o te nui o te hiko e whakaputaina ana. "E whakaatu ana tēnei i te kaha o te rangahau ki te whakapai ake i te pai o te taputapu me te whakaiti i te utu mō ia watt o ngā kōwae," te kī a Cordell.
E kī ana te tuhinga i roto i te puka hautaka, nā Michael Woodhouse rāua ko Emily Warren i tuhi, he taurangi hihiri te whai huatanga o te kōwae i roto i te matapae i te utu o ngā kōwae whakarārangi nā te mea he maha atu ngā taurangi kua rerekē, ā, ka haere tonu te rerekētanga kia taea ai te whakatutuki i ngā taumata whai huatanga me te roa e hiahiatia ana mō te PV e whai hua ana i te taha pakihi. Me 25% te iti rawa o te whai huatanga o ngā kōwae whakarārangi kia taea ai te whakataetae utu me te whakamahi tahi me ētahi atu hangarau pūngao rā. Ko te taahiraa e whai ake nei i roto i te hokohoko o ngā kōwae whakarārangi chalcogenide/silicon ko te whakapai ake i te pono o te hangarau me te whakawhānui ake i te rohe o ngā taputapu whai hua ki te rahi katoa o te kōwae me te pupuri tonu i te mahi.
