Highly efficient bifacial semitransparent perovskite solar cells based on molecular doping of CuSCN hole transport layer*

Chinese Physics B (2020)

Shixin Hou Biao Shi Pengyang Wang Yucheng Li Jie Zhang

Coper thiocyanate (CuSCN) is generally considered as a very hopeful inorganic hole transport material (HTM) in semitransparent perovskite solar cells (ST-PSCs) because of its low parasitic absorption, high inherent stability, and low cost. However, the poor electrical conductivity and low work function of CuSCN lead to the insufficient hole extraction and large open-circuit voltage loss. Here, 2,3,5,6-tetrafluoro-7,7,8,8-tetracyanoquinodimethane (F4TCNQ) is employed to improve conductivity of CuSCN and band alignment at the CuSCN/perovskite (PVK) interface. As a result, the average power conversion efficiency (PCE) of PSCs is boosted by ≈ 11%. In addition, benefiting from the superior transparency of p-type CuSCN HTMs, the prepared bifacial semitransparent n–i–p planar PSCs demonstrate a maximum efficiency of 14.8% and 12.5% by the illumination from the front side and back side, respectively. We believe that this developed CuSCN-based ST-PSCs will promote practical applications in building integrated photovoltaics and tandem solar cells.

Research and Analysis Based on Pricing of Used Sailboats in the World and Hong Kong

Highlights in Business Economics and Management (2023)

Yi Ding Z. Wang Jiacheng Sun

In order to better complete the evaluation of used sailboat prices, this article succeeded in having a system that can predict the prices of used sailboats and combined various analytical methods to realize the prediction of Hong Kong sailboat prices. This article focuses on the following issues: identifying mathematical models for rational pricing, explaining the effect of regional variables on prices, and simulating the regional impact of sailboat prices. This article consists mainly of the following: First, neural networks and deep learning related models are developed to measure the impact of sailboat characteristics on their pricing from multiple perspectives, and predictions are made for the used sailboats based on these models. Second, a variety of geographical factors are taken into account to analyze the correlation of regions, and regional variables with strong correlation analysis are added and combined with BiLSTM-AT model to explain the influence of regions on listing prices. Then, data on the corresponding variables in Hong Kong were collected, and cluster analysis was performed on regionally relevant factors to construct a multi-regional cluster price model. Last, sensitivity analysis and robustness analysis are performed on the completed model.

Polymeric Surface Modification of NiO_x-Based Inverted Planar Perovskite Solar Cells with Enhanced Performance

ACS Sustainable Chemistry & Engineering (2018)

Yawen Du Chenguang Xin Wei Huang Biao Shi Yi Ding

Interfacial engineering has been considered one of the most effective methods for further enhancing the performance of perovskite solar cells. Herein a facile but effective interfacial engineering method of modifying NiOx coated substrate by PTAA is demonstrated for inverted planar perovskite solar cells. The surface modification by polymeric PTAA could effectively tailor the quality of perovskite absorber layer with larger grain size and better crystallinity by controlling wettability of NiOx surface with varied thickness of hydrophobic PTAA. The improvement of Jsc was ascribed to the improved perovskite film quality with reduced trap state densities. By EIS and TRPL analysis, it was also confirmed that PTAA modification significantly facilitated interfacial charge transfer at the interface between perovskite and PTAA/NiOx due to the gradient band alignment. As a consequence, the highest power conversion efficiency of 17.1% together with negligible hysteresis effect was achieved from planar perovskite solar cells with 0.5 mg/mL optimal concentration of PTAA.

Aluminum and Molybdenum Co-Doped Zinc Oxide Films as Dual-Functional Carrier-Selective Contact for Silicon Solar Cells

ACS Applied Materials & Interfaces (2023)

Zhiyuan Xu Xiaoning Liu Jiakai Zhou Yu Yan Yaya Song

Aluminum-doped zinc oxide (AZO) is considered as a promising candidate as transparent conductive oxide (TCO) for silicon heterojunction solar cells due to its high carrier density, nontoxic nature, and low cost. Herein, it is presented that the transparency of the AZO film can be optimized through co-sputtering of AZO and molybdenum oxide (MoOx). Furthermore, aluminum and molybdenum co-doped zinc oxide (MAZO) can be used as both the TCO layer and electron-selective contact (ESC) for silicon heterojunction solar cells. The surface morphology, cation oxidation state, and optical and electrical properties of all MAZO films are characterized. It is found that the transmittance of all MAZO films is significantly increased at a wavelength of 450-800 nm due to MAZO with a stronger Zn-O bond and a wider band gap. The conductivity of MAZO films is approximate to AZO films at a low MoOx target deposit power (50 W), and the sheet resistance of MAZO films increases significantly by increasing the deposition power up to 100 W. Finally, the optimized MAZO films are used as TCO and ESC for silicon heterojunction solar cells, showing a power conversion efficiency of 19.58%. The results show an effective stage to improve the optical properties of AZO through co-doping and the possibility of applying MAZO as a dual-functional layer for silicon solar cells.

OPTICS-Based Passive Tracking Algorithm for High Maneuvering Targets

Jun Chen Wang Fei Yi Ding Wei Lei

For the high maneuvering target, its motion mode is unknown in advance, so the passive target tracking algorithm using fixed motion model or interactive multi-model cannot match the actual motion mode of the maneuvering target. In order to solve the problem of low tracking accuracy caused by unknown motion model of high maneuvering targets, an OPTICS-based passive tracking algorithm for high maneuvering targets was proposed. The algorithm estimates the target state by using the OPTICS trajectory clustering algorithm when the tracking error is large, and updates the state transition matrix based on the motion model estimates and multi-station passive sensor observations. The simulation results verify that the OPTICS-based passive tracking algorithm for high maneuvering targets proposed in this paper can effectively improve the tracking accuracy of high maneuvering targets, which is beneficial to the realization of low probability of interception tracking.
