We report a novel electron-rich molecule based on 3,4-ethylenedioxythiophene (H101). When used as the hole-transporting layer in perovskite-based solar cell, power-conversion efficiency reached 13.8 % under AM 1.5G simulation. This result is comparable with that obtained using well-known hole transporting material 2,2',7,7'-tetrakis(N,N-di-p-methoxyphenylamine)-9,9'-spirobifluorene (spiro-OMeTAD). first heterocycle-containing achieving >10 such devices, and has great potential to replace...

Three novel hole-conducting molecules (T101, T102 and T103) based on a triptycene core have been synthesized using short routes with high yields. The optical electrochemical properties were tuned by modifying the functional groups, through linking to diphenylamines via phenyl and/or thienyl groups. mesoporous perovskite solar cells fabricated T103 as hole transporting material (HTM) showed power conversion efficiency (PCE) of 12.24% 12.38%, respectively, which is comparable that obtained...
With the emerging electric vehicle (EV) and fast charging technologies, EV load forecasting has become a concern for planners operators of stations (CSs). Due to nonstationary feature traffic flow (TF) erratic nature procedures, is difficult accurately forecast. In this article, TF first predicted using deep-learning-based convolutional neural network (CNN), different forecast uncertainties are evaluated formulate prediction intervals (PIs). Then, arrival rates calculated according...
A novel swivel-cruciform 3,3′-bithiophene based hole-transporting material (HTM) with a low lying highest occupied molecular orbital (HOMO) level for application in perovskite solar cells were synthesized.
Abstract Two new electron‐rich molecules, 2,3,4,5‐tetra[4,4′‐bis(methoxyphenyl)aminophen‐4“‐yl]‐thiophene (H111) and 4,4′,5,5′‐tetra[4,4′‐bis(methoxyphenyl)aminophen‐4”‐yl]‐2,2′‐bithiophene (H112), which contain thiophene cores with arylamine side groups, are reported. When used as the hole‐transporting material (HTM) in perovskite‐based solar cell devices, power conversion efficiencies of up to 15.4 % under AM 1.5G simulation were obtained. This is highest efficiency achieved HTMs not...
