Ngā kaipūtaiao Pāniora mai i te Institute of Materials Science and Technology (ICMS) i Seville whakawhanakehia He pūtau rā ranu rerekē i hangaia i runga i te perovskite, ka taea te huri i te hihi o te rā me te kaha o ngā pata ua e taka ana ki te hiko i te wā kotahi. Ka whakakotahi te hangarau i te pānga photovoltaic matarohia mō te hihi o te rā me te pānga triboelectric mō ngā pata ua. Ko te tikanga, he otinga mō ngā āhuatanga katoa o te rangi.
He māmā noa iho te whakaaro matua: te hanga i tētahi taputapu maha-mahi e tino whai hua ana i roto i ngā āhuatanga huarere rerekē, inā koa i ngā rohe he maha ngā ua. Ka whakamahia e te hoahoa o te pūtau he paparanga perovskite hei whakaputa i te pūngao o te rā, me te paparanga polymer angiangi kua whakakikoruatia ki te fluorinated o CFₓ, he maha ngā āhuatanga nui: he mārama teitei (neke atu i te 90%), he hydrophobicity, me te kaha ki te whakaputa i te pūngao triboelectric.
Ka whakatakotoria tēnei paparanga tiaki i te pāmahana rūma i roto i te korehau mā te whakamahi i te rehu plasma, ka tiaki i te perovskite tairongo mai i te makuku, ā, i te wā kotahi ka taea te kohi pūngao mai i ngā pānga o te pata ua. Ina pā te pata ua ki tētahi mata, ka wehea, ka puta te wehenga o te pa me te utu i waenga i ngā rauemi, ka puta he pā hiko.
I whakaatuhia e ngā tauira whakamātautau he pai o te photovoltaic he 17,9%. He tino whakamiharo te mahi a te wāhanga triboelectric o te taputapu: he ngaohiko ara iahiko tuwhera tae atu ki te 110 V mō ia pata me te mātotoru mana mōrahi tata ki te 4 mW/m². I roto i te aratau ranu, i te haurua o te hihi o te rā (500 W/m²), i tutuki he mātotoru iahiko ara iahiko poto o te 11,6 mA/m², ā, ko te ngaohiko tihi mai i ngā pata i tae atu ki te 12 V. I hangaia hoki e ngā kairangahau he whakaaturanga i reira ka utua e te pūtau ranu he supercapacitor me te whakakaha i te rīpene LED mā roto i te kaitahuri.
Ko te whanaketanga, i whakahaerehia e ngā kaupapa 3DScavengers me Drop Ener me te tautoko mai i te European Research Council me te Next Generation Fund, e whakatuwhera ana i te kuaha ki ngā panera rā maha atu ngā whakamahinga. Ahakoa ko te hihi o te rā tonu te pūtake matua o te hiko, ka tere ake te utu pākahiko i te rangi kapua nā te pūngao tāpiri mai i te ua. Heoi anō, he uaua tonu te whakawhānui ake i te hangarau ki tua atu i ngā tauira taiwhanga, ā, me rangahau anō.
