“…The maximum solar cell parameter values such as V oc , J sc , FF and η were recorded at 1.248533V, 31.35351045mA/cm 2 84.8548% and 33.2172%, respectively. These agreed with [35], experimentally, which revealed that, SnO 2 was deposited at a rate of around 2 nm/min, and its thickness ranged from ~30 to ~180 nm. Also, [36]showed that the thickness of the ETM signi cantly in uences solar cell optimization.…”

Obtaining cheap Electronic Transparent Materials (ETM) and Hole Transparent Materials (HTM) is an important challenge for researchers in perovskite solar cells. we used the SCAPS software in order to determine the properties of CH3NH3SnI3-based solar cells with different ETM and HTM layers, such as (IGZO, SnO2, TiO2, ZnO) and (Spiro-OMeTAD, NiO, Cu2O, and CuO), respectively. Our results predict that among these ETMs, the SnO2 is the most promising to result in high photovoltaic (PV) efficiency in combination with Spiro-OMeTAD based HTM. In addition the perovskite absorber's thicknesses are optimized to achieve maximum photovoltaic efficiency. In order to increase efficiency, layer thickness in cell structures can be optimized by fixing the thickness of the first two layers while altering the thickness of the third. The perovskite solar cell's planar structure consists of ETM (SnO2)/perovskite absorber (CH3NH3SnI3) / HTM (Spiro-OMeTAD)/ and Gold (Au) as a back contact. Also, it improved the solar cell performance by optimizing the absorber thickness, which was 1 µm. With these considerations, the power conversion efficiency of 33.2698% is obtained. Also, we explore the effect of the defect at the perovskite/SnO2 interface on solar cell performance.

“…Therefore, a suitable doping selection mechanism is based on the high-impedance nature of the material. Based on this condition, PbO, Al 2 O 3 , and ZnO were utilized as a potential inorganic metal-oxide-doped SnO 2 ETL in PSCs, forming a double ETL [ 105 , 106 , 107 ]. Reference samples with bare FTO and FTO/SnO 2 are shown in the top-view SEM images in Figure 16 a–f [ 105 ].…”

Perovskite solar cells (PSCs) have garnered considerable attention over the past decade owing to their low cost and proven high power conversion efficiency of over 25%. In the planar heterojunction PSC structure, tin oxide was utilized as a substitute material for the TiO2 electron transport layer (ETL) owing to its similar physical properties and high mobility, which is suitable for electron mining. Nevertheless, the defects and morphology significantly changed the performance of SnO2 according to the different deposition techniques, resulting in the poor performance of PSCs. In this review, we provide a comprehensive insight into the factors that specifically influence the ETL in PSC. The properties of the SnO2 materials are briefly introduced. In particular, the general operating principles, as well as the suitability level of doping in SnO2, are elucidated along with the details of the obtained results. Subsequently, the potential for doping is evaluated from the obtained results to achieve better results in PSCs. This review aims to provide a systematic and comprehensive understanding of the effects of different types of doping on the performance of ETL SnO2 and potentially instigate further development of PSCs with an extension to SnO2-based PSCs.

“…This preparation method is simple and effective, but the growth time of SnO 2 thin shells is up to 48 h, which is not suitable for mass production. ZnO possesses optical and electrical properties similar to those of SnO 2 , and it is known that the metal activity of Zn is more potent than that of Sn, which means that Zn is much more easily oxidized compared with Sn under the same conditions. Therefore, the growth of ZnO shells on the outer layer of the AgNWs is expected to take a shorter time than that of SnO 2 shells.…”

Silver nanowires (AgNWs) have received much attention from researchers for their superior optoelectronic properties and are thought to be the most potential substitute for indium−tin oxide. However, the poor stability of the AgNW network when exposed to the atmospheric environment for a long time is a pivotal problem. The surface of the AgNW is easily oxidized, and the NW scale is too small, accelerating the degradation mechanism of Ag, which is limited in practical applications. In this study, a simple and inexpensive solution approach is innovatively proposed to prepare ultrathin Ag@ZnO NW networks with core−shell structure to improve the thermal, electrical, and chemical stability of AgNWs. The formed Ag@ZnO NW network has a high transmission of 81% with a low sheet resistance of 7.5 Ω/sq. More importantly, the Ag@ZnO NW network can withstand high temperatures up to 280 °C without performance degradation. In addition, the Ag@ZnO NW network shows excellent thermal and chemical stability and maintains the original performance under harsh conditions such as high temperature, high relative humidity, ultraviolet ozone, strong oxidants (Na 2 S), and salinity (NaCl). Finally, the application of Ag@ZnO NW flexible transparent conductive electrodes (FTCEs) in an electrochromic device is successfully demonstrated to verify the applicability of Ag@ZnO NW FTCEs, and the electrochromic device has cyclability and quick responsiveness.
