I-Italy ithuthukise imodyuli yelanga engagcina ukusebenza kahle kokuqala kwama-90% ku-85°C

Isingeniso: Ithimba labacwaningi eliholwa yiNyuvesi yaseTor Vergata eRome, e-Italy likhiqize imojuli yelanga ye-peroxide enendawo esebenza kahle engu-42.8 cm2 kanye nendawo yokuvula engamasentimitha-skwele angama-50.Iphaneli yelanga iqukethe amabhethri e-peroxide angu-14 asebenza kahle ngo-20% ochungechungeni.Ngemva kwamahora angu-800 okucindezeleka okushisayo ku-85°C, kusengakwazi ukugcina ukusebenza kahle kokuqala okungama-90%.

Ithimba labacwaningi bamazwe ngamazwe lasebenzisa uhlobo olusha lwesu lokusebenzisa izidakamizwa ukuklama imojuli yelanga ye-peroxide.Kuthiwa uma kuqhathaniswa namanye amadivaysi asekelwe kwi-peroxide, imojula ingafinyelela ukusebenza kahle okuphezulu ngenkathi igcina ibalulekile Ukuzinza komsebenzi.

Nakuba amangqamuzana elanga e-peroxide abonakala esendleleni eya ekukhiqizeni ngobuningi, abantu basenesithakazelo kubuchwepheshe ngenxa yokukhathazeka mayelana nokuzinza kwe-hole transport layer (HTL) nokuzwela kwayo ezimweni zomoya.abathintekayo.

Ososayensi bathi bangashintsha isisindo samangqamuzana (MW) se-hole transport layer material (HTM) efakwe nge-polytriarylamine (PTAA).Bachaza: “Ukwanda kwe-monotonic ekusebenzeni kahle kokuguqulwa kwamandla njengomsebenzi we-MW kuhlobene nokwenyuka okufanayo kwe-open circuit voltage (VOC), i-short circuit current (JSC), kanye ne-filter factor (FF).Ngale ndlela, ukuhamba kweshaje ngaphakathi kwe-HTL kanye Nezokuthutha zenkokhiso kusixhumi esibonakalayo se-peroxide/HTL kwenyuke ngohlelo lobukhulu.”

Bathe lokhu kuthuthukiswa kufinyelelwa ngomphumela ohlangene wesu lokusebenzisa izidakamizwa kanye ne-MW tuning, okuzuze ukukhishwa kwe-polaron kuchungechunge lwe-polymer.Ucwaningo lwesayensi lwabonisa ukuthi ukwakheka kwama-polaron kumaseli elanga e-peroxide kuyinto engenzeka eyenza amabhethri anjalo aphumelele ngokukhethekile, nakuba indlela engemuva kwama-polaron ingaziwa ngokuphelele.I-poleon iwukuhlanekezela okushintsha ngokushesha endaweni ye-athomu yento.Yakha nxazonke i-electron ehambayo ngezigidigidi ezimbalwa zomzuzwana, bese iyanyamalala.

Ngokwesisekelo sengqikithi yendawo esebenzayo yamasentimitha-skwele angu-42.8 kanye nendawo yokuvula engamasentimitha-skwele angu-50, uchungechunge lwamabhethri e-peroxide angu-14 ane-20% esebenza kahle luxhunywe ochungechungeni ukuze kwakhiwe iphaneli nge-17% ephumelelayo.Ukwanda kwezigxobo ezigxilile kungqimba lwe-HMW PTAA akunikezeli nje kuphela umnikelo obalulekile ekusebenzeni kahle kwedivayisi, kodwa futhi kunomthelela omuhle ku-peroxide lattice yengqimba engaphansi, ngaleyo ndlela kuthuthukisa ukuzinza kwayo jikelele.Kuthiwa ngemva kwamahora angu-1080 okucindezeleka okushisayo ku-85 degrees Celsius, ibhethri lisengakwazi ukugcina ukusebenza kahle kokuqala okungaphezu kuka-90%, futhi ngemva kwamahora angu-160 okuchayeka, lisengakwazi ukugcina ukusebenza kahle kokuqala kwama-87%.Iphaneli yelanga isengakwazi ukugcina ukusebenza kahle kokuqala okungaphezu kuka-90% ngemva kwamahora angu-800 okucindezeleka okushisayo ku-85 degrees Celsius.

Le module yethulwa ephepheni elithi "Ukufeza imodyuli yelanga ye-perovskite ezinzile engaphezu kwe-17% ngokulungiswa kokuhlelwa kwe-polaron ye-polymer hole transport layer" enyatheliswa ku-"Nano Energy".Ithimba labacwaningi lihlanganisa ososayensi base-Tor Vergata University e-Rome, e-Italy, e-University College London, e-Cambridge University e-UK, kanye ne-Max Planck Institute for Polymer Research eJalimane.
