I-Italiya iphuhlise imodyuli yelanga enokugcina ukusebenza kakuhle kwe-90% kwi-85 ° C

Intshayelelo: Iqela lophando elikhokelwa yiYunivesithi yaseTor Vergata eRoma, eItali livelise imodyuli yelanga yeperoxide enendawo esebenzayo iyonke eyi-42.8 cm2 kunye nendawo yokuvula eyi-50 square centimeters.Iphaneli yelanga ineebhetri ezili-14 zeebhetri ezine-20% esebenzayo kuthotho.Emva kweeyure ze-800 zoxinzelelo lwe-thermal kwi-85 ° C, isenokugcina ukusebenza kakuhle kokuqala kwe-90%.

Iqela lophando lwamazwe ngamazwe lisebenzise uhlobo olutsha lweqhinga le-doping ukuyila imodyuli yelanga ye-peroxide.Kuthiwa ukuba xa kuthelekiswa nezinye izixhobo ezisekelwe kwi-peroxide, imodyuli inokufikelela ekusebenzeni okuphezulu ngelixa igcina ibalulekile Ukuzinza komsebenzi.

Nangona iiseli zelanga ze-peroxide zibonakala zisendleleni eya kwimveliso yobuninzi, abantu basenomdla kwithekhinoloji ngenxa yeenkxalabo malunga nokuzinza kwe-hole transport layer (HTL) kunye nokuvakalelwa kwayo kwiimeko ze-atmospheric.abachaphazelekayo.

Oososayensi bathi banokutshintsha ubunzima be-molecular (MW) ye-hole transport layer material (HTM) doped with polytriarylamine (PTAA).Bachaza: "Ukonyuka kwe-monotonic ekusebenzeni kokuguqulwa kwamandla njengomsebenzi we-MW kuhambelana nokunyuka okufanayo kwi-voltage yesiphaluka evulekile (VOC), i-short circuit current (JSC), kunye ne-fiction factor (FF).Ngale ndlela, ukuhamba kwentlawulo ngaphakathi kwe-HTL kunye nokuThuthwa kwentlawulo kwi-peroxide/HTL interface yonyuke ngomyalelo wobukhulu.

Bathe olu phuculo luphunyezwa ngesiphumo esidityanisiweyo seqhinga lokusebenzisa iziyobisi kunye nokulungiswa kwe-MW, okuthe kwaphunyelelwa ukususwa kwe-polaron kwikhonkco lepolymer.Uphando lwezenzululwazi lubonise ukuba ukubunjwa kwee-polaron kwiiseli zelanga ze-peroxide yinto enokwenzeka eyenza ukuba iibhetri ezinjalo zisebenze ngokukodwa, nangona indlela esemva kwe-polaron ingaziwa ngokupheleleyo.Ipoleon kukugqwetheka okutshintsha ngokukhawuleza kwileti yeathom yento.Yenza malunga ne-electron ehambayo kwi-trillionths embalwa yomzuzwana, kwaye iyanyamalala.

Ngokwesiseko sommandla osebenzayo opheleleyo we-42.8 square centimeters kunye nommandla wokuvula we-50 square centimeters, uchungechunge lwe-14 yeebhetri ze-peroxide kunye ne-20% ye-effective idibaniswe kwi-series ukwakha ipaneli ene-17%.Ukwandiswa kweepali ezinqamlekileyo kwi-HMW PTAA layer akunikezeli nje igalelo elibalulekileyo ekusebenzeni okuphezulu kwesixhobo, kodwa kunefuthe elihle kwi-peroxide lattice yomgangatho ongaphantsi, ngaloo ndlela kuphuculwe ukuzinza kwayo jikelele.Kuthiwa emva kweeyure ze-1080 zoxinzelelo lwe-thermal kwi-85 degrees Celsius, ibhetri isenokugcina ukusebenza kakuhle kokuqala okungaphezulu kwe-90%, kwaye emva kweeyure ze-160 zokuvezwa, inokugcina ukusebenza kakuhle kokuqala kwe-87%.Iphaneli yelanga isenokugcina ukusebenza kakuhle kokuqala okungaphezulu kwe-90% emva kweeyure ze-800 zoxinzelelo lwe-thermal kwi-85 degrees Celsius.

Le modyuli yaziswa kwiphepha elithi "Ukufezekisa imodyuli yelanga ezinzileyo ye-perovskite engaphezulu kwe-17% ngokuhlengahlengiswa kwelungiselelo le-polaron ye-polymer hole transport layer" epapashwe kwi "Nano Energy".Iqela lophando libandakanya izazinzulu ezivela kwiYunivesithi yaseTor Vergata eRoma, eItali, kwiYunivesithi yaseLondon, kwiYunivesithi yaseCambridge e-UK, kunye neMax Planck Institute yoPhando lwePolymer eJamani.
