Abstract

Perovskite solar cells (PSCs) have garnered significant attention in photovoltaics due to their simple fabrication process, low cost, and excellent photovoltaic performance. To enhance the power conversion efficiency (PCE), we designed a PSC incorporating a charge transport layer with a dual inverted pyramid reflectance-reducing structure. The effect of the depth of the inverted pyramid spires on the PCE of PSCs was investigated. The results indicate that introducing the dual inverted pyramid in PSCs with the structure of ITO/PEDOT: PSS/MAPbI₃/SnO₂/Ag significantly reduces light reflectivity and enhances light absorption. This structural optimization facilitates better light energy capture, which improves PCE of PSCs. Additionally, the dual inverted pyramid structure increases the interfacial contact area between the light absorption layer and the charge transport layer and shortens carrier transport distances, contributing to improved carrier transport efficiency. The PSCs based on the dual inverted pyramid structure demonstrate outstanding photovoltaic performance, with a maximum short-current density (Jsc) of 26.24 mA/cm² and a PCE of 24.92%. Compared to the conventional PSCs without the pyramid structure, the Jsc and PCE increased by 16.3% and 11.3%, respectively.

利用双倒金字塔结构优化光吸收，显著提高钙钛矿太阳能电池的性能

钙钛矿太阳能电池（PSCs）因其制造工艺简单、成本低、光伏性能优异而在光伏领域受到广泛关注。为了提高功率转换效率（PCE），我们设计了一种具有双倒金字塔减反射结构的电荷传输层的PSC。研究了倒金字塔尖顶深度对聚苯乙烯复合材料PCE的影响。结果表明，在ITO/PEDOT: PSS/MAPbI3/SnO2/Ag结构的PSCs中引入双倒金字塔结构可以显著降低光反射率，增强光吸收。这种结构优化有利于更好的光能捕获，从而提高PSCs的PCE。此外，双倒金字塔结构增加了光吸收层和电荷输运层之间的界面接触面积，缩短了载流子输运距离，有助于提高载流子输运效率。基于双倒金字塔结构的PSCs具有出色的光伏性能，最大短路密度（Jsc）为26.24 mA/cm2， PCE为24.92%。与没有金字塔结构的传统PSCs相比，Jsc和PCE分别提高了16.3%和11.3%。

期刊介绍： he Journal of Computational Electronics brings together research on all aspects of modeling and simulation of modern electronics. This includes optical, electronic, mechanical, and quantum mechanical aspects, as well as research on the underlying mathematical algorithms and computational details. The related areas of energy conversion/storage and of molecular and biological systems, in which the thrust is on the charge transport, electronic, mechanical, and optical properties, are also covered. In particular, we encourage manuscripts dealing with device simulation; with optical and optoelectronic systems and photonics; with energy storage (e.g. batteries, fuel cells) and harvesting (e.g. photovoltaic), with simulation of circuits, VLSI layout, logic and architecture (based on, for example, CMOS devices, quantum-cellular automata, QBITs, or single-electron transistors); with electromagnetic simulations (such as microwave electronics and components); or with molecular and biological systems. However, in all these cases, the submitted manuscripts should explicitly address the electronic properties of the relevant systems, materials, or devices and/or present novel contributions to the physical models, computational strategies, or numerical algorithms.
