Italy yapanga gawo la solar lomwe limatha kukhala ndi mphamvu yoyambira 90% pa 85 ° C

Chiyambi: Gulu lofufuza motsogozedwa ndi Yunivesite ya Tor Vergata ku Rome, Italy lapanga gawo la solar la peroxide lomwe lili ndi gawo lokwanira la 42.8 cm2 ndi malo otsekera a 50 masikweya sentimita.Solar panel imakhala ndi mabatire 14 a peroxide omwe ali ndi mphamvu 20% motsatizana.Pambuyo pa maola 800 akupsinjika kwa kutentha pa 85 ° C, amatha kukhalabe ndi mphamvu zoyamba za 90%.

Gulu la kafukufuku wapadziko lonse lapansi linagwiritsa ntchito njira yatsopano yopangira doping kupanga gawo la dzuwa la peroxide.Akuti poyerekeza ndi zipangizo zina zozikidwa ndi peroxide, gawoli likhoza kukwaniritsa bwino kwambiri pokhalabe lofunika Kukhazikika kwa ntchitoyo.

Ngakhale ma cell a dzuwa a peroxide akuwoneka kuti ali panjira yopangira misa, anthu akadali ndi chidwi ndiukadaulo chifukwa chodera nkhawa za kukhazikika kwa gawo loyendetsa dzenje (HTL) komanso kukhudzidwa kwake ndi zinthu zakuthambo.okhudzidwa.

Asayansi anati akhoza kusintha maselo kulemera (MW) wa dzenje zoyendera wosanjikiza zakuthupi (HTM) doped ndi polytriarylamine (PTAA).Iwo adalongosola kuti: "Kuwonjezeka kwa monotonic kwa kutembenuka kwa mphamvu monga ntchito ya MW kumagwirizana ndi kuwonjezeka kofanana kwa magetsi otseguka (VOC), short circuit current (JSC), ndi fill factor (FF).Mwanjira imeneyi, kusuntha kwa ndalama mkati mwa HTL ndi Magalimoto oyendetsa pamawonekedwe a peroxide/HTL kwachulukirachulukira.

Ananenanso kuti kusinthaku kumatheka chifukwa cha kuphatikiza kwa doping strategy ndi MW tuning, zomwe zapangitsa kuti polaron isasunthike pa unyolo wa polima.Kafukufuku wasayansi adawonetsa kuti mapangidwe a polarons mu ma cell a dzuwa a peroxide ndi chinthu chomwe chimapangitsa mabatire oterowo kukhala othandiza kwambiri, ngakhale kuti njira yomwe ili kumbuyo kwa polaroni sikudziwika.A poleon ndi kupotoza kofulumira kwa ma atomiki a chinthu.Zimapanga mozungulira electron yosuntha mu ma triliyoni angapo a sekondi, ndiyeno imasowa.

Pamaziko a okwana ogwira m'dera 42,8 lalikulu masentimita ndi malo pobowo 50 lalikulu masentimita, 14 mndandanda wa mabatire peroxide ndi 20% dzuwa olumikizidwa mu mndandanda kumanga gulu ndi 17% dzuwa.Kuwonjezeka kwa mizati defocusing mu HMW PTAA wosanjikiza osati amapereka chothandiza kwambiri kwa dzuwa mkulu wa chipangizo, komanso ali ndi zotsatira zabwino pa peroxide latisi wa m'munsi wosanjikiza, potero kumapangitsanso bata wake wonse.Akuti pambuyo pa maola 1080 akupsinjika kwamafuta pa 85 digiri Celsius, batire imatha kukhalabe yogwira ntchito yopitilira 90%, ndipo pakatha maola 160 akuwonekera, imatha kukhalabe ndi mphamvu zoyambira 87%.Dzuwa la solar limatha kukhalabe ndi mphamvu yoyambira yopitilira 90% pambuyo pa maola 800 akupsinjika kwamafuta pa 85 digiri Celsius.

Gawoli linayambika mu pepala "Kukwaniritsa gawo lokhazikika la dzuwa la perovskite loposa 17% mwa kusintha kwa polaron ya polima dzenje zoyendetsa galimoto" lofalitsidwa mu "Nano Energy".Gulu lofufuza likuphatikizapo asayansi ochokera ku yunivesite ya Tor Vergata ku Rome, Italy, University College London, Cambridge University ku UK, ndi Max Planck Institute for Polymer Research ku Germany.
