Italy yakagadzira solar module inogona kuchengetedza kushanda kwekutanga kwe90% pa85 ° C

Nhanganyaya: Boka rekutsvagisa rinotungamirwa neTor Vergata University kuRome, Italy rakagadzira peroxide solar module ine nzvimbo yese inoshanda ye 42.8 cm2 uye nzvimbo yekuvhura inoita 50 square centimeters.Iyo solar panel ine gumi nemana akateedzana mabhatiri eperoxide ane 20% kunyatsoita munhevedzano.Mushure memaawa 800 ekushushikana kwekupisa pa85 ° C, inogona kuramba ichichengetedza kushanda kwekutanga kwe90%.

Chikwata chekutsvagisa chepasirese chakashandisa rudzi rutsva rwedoping zano kugadzira peroxide solar module.Zvinonzi kana zvichienzaniswa nemamwe peroxide-yakavakirwa madivayiri, iyo module inogona kuwana yakakwira mashandiro apo ichichengetedza yakakosha Kugadzikana kwebasa.

Kunyange zvazvo peroxide yezuva masero anoita seari munzira yekugadzirwa kwehuwandu, vanhu vachiri kufarira tekinoroji nekuda kwekunetseka pamusoro pekugadzikana kwegomba rekutakura dhizaini (HTL) nekunzwa kwayo kumamiriro ekunze.vakanganiswa.

Masayendisiti akati vanogona kushandura huremu hwema molecular (MW) yegomba rekutakura layer zvinhu (HTM) doped ne polytriarylamine (PTAA).Vakatsanangura kuti: "Kuwedzera kwe monotonic musimba rekushandura simba senge basa reMW kune hukama nekuwedzera kwakafanana muvhuvhu remhepo voltage (VOC), pfupi dunhu ikozvino (JSC), uye kuzadza chinhu (FF).Nenzira iyi, kufamba kwechaji mukati meHTL uye Iyo yekuchaja yekufambisa paperoxide/HTL interface yakawedzera nekurongeka kwehukuru.

Vakataura kuti kuvandudzwa uku kunowanikwa kuburikidza nekubatanidzwa kwekuita doping zano uye MW tuning, iyo yakawana polaron dislocation pane polymer cheni.Ongororo yesainzi yakaratidza kuti kuumbwa kwepolar mu peroxide solar masero chinhu chinogoneka chinoita kuti mabhatiri akadaro ashande zvakanyanya, kunyangwe iyo nzira iri kumashure kwepolar isingazivikanwi zvachose.Poleon kumonyaniswa kuri kukurumidza kushanduka muatomic lattice yechinhu.Inoumba yakatenderedza erekitironi inofamba mumatrillionths mashoma esekondi, yobva yanyangarika.

Pahwaro hwehuwandu hunobudirira hwe 42.8 square centimeters uye nzvimbo yekuvhara ye 50 square centimeters, 14 mutsara wemabhatiri eperoxide ane 20% kunyatsoshanda akabatanidzwa mumutsara wekuvaka pani ine 17% inoshanda.Kuwedzera kwematanda ekudzikisa muHMW PTAA layer hakungopei rubatsiro rwakakosha pakubudirira kwepamusoro kwechigadziro, asi kunewo maitiro akanaka pane peroxide lattice yepasi pasi, zvichiita kuti iwedzere kugadzikana kwayo.Zvinonzi mushure memaawa 1080 ekushushikana kwekushisa pa 85 degrees Celsius, bhatiri rinogona kuchengetedza kushanda kwekutanga kwe90%, uye mushure memaawa 160 ekuonekwa, inogona kuchengetedza kushanda kwekutanga kwe87%.Iyo solar panel ichiri kukwanisa kuchengetedza kushanda kwekutanga kweinopfuura 90% mushure memaawa mazana masere ekushushikana kwekupisa pa85 degrees Celsius.

Iyi module yakaunzwa mupepa "Kuwana yakagadzikana perovskite-mhando solar module inopfuura 17% kuburikidza nekugadziriswa kwepolaron kuronga kwepolymer hole transport layer" yakabudiswa mu "Nano Energy".Chikwata chekutsvaga chinosanganisira masayendisiti kubva kuTor Vergata University muRome, Italy, University College London, Cambridge University kuUK, uye Max Planck Institute for Polymer Research muGermany.
