This study has selected sorts of comments about MI’s products from its customers’ as research objects, then we used the theory of Rooting to analyze those objects, and explored the Customer Experience Dimensions’ type, characteristics and the way to impact others. The results come as follows: First of all, the Customers Experience Dimensions are consisted of nine major categories defined as Value Perception Experience, Sensory Experience, Quality Assurance Experience, Parts Experience, Purchase Experience, Service Experience, Brand Comparison Experience, Compensating Experience, Brand Reliance Experience respectively. Secondly, we put these nine major categories above all to compare the conclusions with the previous research, then we analyzed and integrated them, and finally obtained seven major categories containing Purchasing Website, Product Rendering, Delivery Experience, Transaction Convenience, Safety and Security, Brand Reliance, Marketing Communications respectively. In addition, we have conducted a further investigation to draw three types about the Customer Experience named Function Experience, Purchasing and Service Experience, and Brand Experience. Last but not the least, this paper has definitely provided the basis theory of how does the Customer Experience affect the Brand Loyalty for future research, as well as guided a definite orientation.

Tin oxide (SnO2) has recently received increasing attention as an electron transport layer (ETL) in planar perovskite solar cells (PSCs) and is considered a possible alternative to titanium oxide (TiO2). However, planar devices based on pure solution‐processed SnO2 ETL still have hysteresis, which greatly limits the application of SnO2 in high‐efficiency solar cells. Herein, to address this issue, a hybrid ETL of SnO2 and carbon nanotubes (CNTs) is fabricated by a simple thermal decomposing of a mixed solution of SnCl4·5H2O and pretreated CNTs (termed SnO2–CNT). The addition of CNTs can significantly improve the conductivity of SnO2 films and reduce the trap‐state density of SnO2 films, which benefit carrier transfer from the perovskite layer to the cathode. As a result, a high efficiency of 20.33% is achieved in the hysteresis‐free PSCs based on SnO2–CNT ETL, which shows 13.58% enhancement compared with the conventional device (power conversion efficiency = 17.90%).

Solution‐processed Sb2S3 planar heterojunction solar cells have shown great progress in power conversion efficiency (PCE) in recent years. However, a conventional solution process yields Sb2S3 films with a small grain size. Herein, an alcohol vapor post‐annealing strategy is reported that uses alcohol vapors to facilitate grain growth of Sb2S3 films during annealing, achieving films with a larger grain size and better crystallinity. A series of alcohols with different polarities are used for the vapor post‐annealing. Methanol with the highest polarity provides films with the largest grain size. As a result, the Sb2S3 films prepared via vapor post‐annealing show enhanced light absorption, longer carrier lifetime, and less carrier recombination, which are verified by photoluminescence, transient photovoltage, suns‐short‐circuit photocurrent density, and suns‐open‐circuit voltage measurements. The Sb2S3 solar cells post‐annealed with methanol vapor exhibit a PCE of 5.27%, showing a drastic improvement of 31% compared with the non‐treated devices. The alcohol vapor post‐annealing approach presents a new avenue toward controlling the morphology and crystallinity of solution‐processed Sb2S3 films and achieving efficient Sb2S3 solar cells.

Dye-sensitized solar cells (DSSCs) are solar energy conversion devices with high efficiency and simple fabrication procedures. Developing transparent counter electrode (CE) materials for bifacial DSSCs can address the needs of window-type building-integrated photovoltaics (BIPVs). Herein, transparent organic-inorganic hybrid composite films of molybdenum disulfide and poly(3,4-ethylenedioxythiophene) (MoS 2 /PEDOT) are prepared to take full advantage of the conductivity and electrocatalytic ability of the two components. MoS 2 is synthesized by hydrothermal method and spin-coated to form the MoS 2 layer, and then PEDOT films are electrochemically polymerized on top of the MoS 2 film to form the composite CEs. The DSSC with the optimized MoS 2 /PEDOT composite CE shows power conversion efficiency (PCE) of 7% under front illumination and 4.82% under back illumination. Compared with the DSSC made by the PEDOT CE and the Pt CE, the DSSC fabricated by the MoS 2 /PEDOT composite CE improves the PCE by 10.6% and 6.4% for front illumination, respectively. It proves that the transparent MoS 2 /PEDOT CE owes superior conductivity and catalytic properties, and it is an excellent candidate for bifacial DSSC in the application of BIPVs., Competing Interests: The authors declare no competing financial interest., (Copyright © 2020 American Chemical Society.)

Interfaces in Sb 2 S 3 thin-film solar cells strongly affect their open-circuit voltage ( V OC ) and power conversion efficiency (PCE). Finding an effective method of reducing the defects is a promising approach for increasing the V OC and PCE. Herein, the use of an inorganic salt SbCl 3 is reported for post-treatment on Sb 2 S 3 films for surface passivation. It is found that a thin SbCl 3 layer could form on the Sb 2 S 3 surface and produce higher efficiency cells by reducing the defects and suppressing nonradiative recombination. Through density functional theory calculations, it is found that the passivation of the Sb 2 S 3 surface by SbCl 3 occurs via the interactions of Sb and Cl in SbCl 3 molecules with S and Sb in Sb 2 S 3 , respectively. As a result, incorporating the SbCl 3 layer highly improves the V OC from 0.58 to 0.72 V; an average PCE of 6.9 ± 0.1% and a highest PCE of 7.1% are obtained with an area of 0.1 cm 2 . The achieved PCE is the highest value in the Sb 2 S 3 planar solar cells. In addition, the incorporated SbCl 3 layer also leads to good stability of Sb 2 S 3 devices, by which 90% of the initial performance is maintained for 1080 h of storage under ambient humidity (85 ± 5% relative humidity) at room temperature.
