“…2c), the peaks at 952.5 and 932.4 eV can be attributed to the binding energies (BEs) of Cu 2p 1/2 and Cu 2p 3/2 , respectively, in agreement with the Cu-N position [23]. Mean-while, the peak at 947 eV is attributed to the oxide species due to the exposure to ambient conditions, which is consistent with previous reports [24,25].

Perovskite oxides with flexible compositions and electronic structures have great potential for application in electrocatalytic water oxidation reactions. However, few studies have focused on the application of perovskite oxides in electrocatalytic oxidation reactions of organic molecules, probably due to the absence of active species because of the poor conductivity and high energy barrier of the surface reconstruction. Herein, we report Cu 3 N nanosheets with a typical antiperovskite structure as electrocatalysts for selectively converting methanol to formate. The as-prepared antiperovskite nitride Cu 3 N samples exhibit a Faradic efficiency exceeding 90% for methanol to formate over a wide potential range, which was further confirmed by online electrochemical mass spectrometry and in situ infrared reflectance absorption spectroscopy. Moreover, the high-resolution transmission electron microscopy, X-ray absorption spectroscopy, and in situ Raman spectroscopy results indicate that the core-shell structure formed by generating surface Cu(II) species triggers the electrocatalytic methanol oxidation reaction activity, whereas the pristine Cu 3 N core facilitates the electron transport inside the catalyst during the electrocatalytic process.This study provides a modelable scheme for the highly selective conversion of methanol and introduces a novel nonoxide perovskite material for the electrochemical conversion of small-organic molecules.

“…Therefore, the e ciency was improved and linked to the thickness. Finally, we can say that at 20μm with E g,CISSe = 1.7 eV, we obtain an ideal e ciency of the CISSe window layer compared to the measurements indicated in [7], [8].…”

This manuscript presents an optimization of the performances of the CISSe/CdS/ZnO structure. 12 tests were performed for each layer on thickness, gap energy and temperature using SCAPC-1D. Numerical data were compiled with the open circuit voltage, the short circuit density, the fill factor and the efficiency. The results obtained are confirmed with the measurements illustrated in the literature. The analyses indicate a progressive improvement in the performance of the structure for each test; an efficiency of 28.8 % was recorded for the CISSe layer while 30.07 % as an efficiency for CdS and 31.47 % for the absorbent layer. On the other hand, an open circuit voltage does not exceed 1.37V for the whole structure.Thus, these results are satisfied and encouraged.

“…It can be seen in the figure that the surface of the prepared transparent anatase TiO 2 film is extremely smooth, and no grain boundary can be observed even at the condition of 1 μm scale, which is much smoother than the FTO glass substrate used by us. It can be regarded as a highly transparent anatase block. , Compared with the traditional anatase NP film, the anatase TiO 2 film with high transparency has almost no interface between particles, which greatly reduces the difficulty of carrier transmission and the recombination of a large number of electrons and holes caused by the interface. It is an ideal electrode material for transparent cells .…”

In this work, we propose a strategy that is different from the traditional technology of increasing the specific area of the TiO 2 film to improve the carrying capacity of QDs in QDSSCs. Transparent anatase TiO 2 films are prepared by improving the optical transmittance of the photoanode TiO 2 film so that the attached QDs can capture more photons and improve the efficiency of utilizing QDs. This QDSSC preparation technology sacrifices part of QDs loading but improves the utilization efficiency of QDs. At the same time, the transparent bulk TiO 2 film decreases the transmission distance of photogenerated charge carriers, reduces the cross-interface transport, optimizes the transmission path, and reduces the carrier capture composite rate compared with the TiO 2 particle film. Therefore, it not only increases the V oc , FF, and PCE of QDSSCs to 0.628 V, 54.7, and 6.166%, respectively, but also has greater transparency. It meets the demand for solar cell transparency in practical applications and has a wider range of applications and better aesthetics. The mechanism simulation and theoretical analysis of photothermal conversion and electromagnetic mechanism show that the barrier of carrier transfer in bulk transparent anatase TiO 2 is lower than the physical barrier between anatase TiO 2 NPs. The advantages of the anatase transparent TiO 2 film in the process of photogenerated charge carrier transmission are verified. It provides an idea for the development of QDSSCs. It also brings the technology of transparent TiO 2 film to related fields.
