摘要

在过去几十年中，人们采用了许多科学和理论方法来提高太阳能电池的效率。为了提高光伏电池的效率，本研究采用了分级方法，并对温度、串联电阻、不同的缺陷密度和分级层厚度进行了修改。本文对线性分级器件结构（Au/PTAA/CsPbBr3-xIx/TiO2/FTO）进行了理论研究。线性分级的过氧化物层可以吸收不同波长的多种光谱，有助于改善太阳能电池的特性。在该装置中，聚三聚芳胺（PTAA）充当 HTL，二氧化钛充当 ETL。我们使用仿真程序 SCAPS-1D 进行理论分析。模拟结果如下：PCE 为 20.50%，JSC 为 18.071 mA cm-2，VOC 为 1.4531 V，FF 为 78.08%。

Innovative design strategies for solar cells: Theoretical examination of linearly graded perovskite solar cell with PTAA as HTL

Over the previous few decades, numerous scientific and theoretical approaches have been employed to increase solar cell efficiency. To improve PV cell efficiency, this study employs grading methodologies and modifies temperature, series resistance, different defect densities, and graded layer thickness. The paper presents a theoretical examination of the linearly graded device structure (Au/PTAA/CsPbBr_3-xI_x/TiO₂/FTO). A linearly graded perovskite layer, responsible for absorbing a wide range of light spectra with different wavelengths, assists in bettering the solar cell's characteristics. In this device, polytriarylamine (PTAA) acts as an HTL, and TiO₂ acts as an ETL. SCAPS-1D, a simulation program, is used for our theoretical analysis. The output results obtained from the simulation are as follows: PCE of 20.50 %, J_SC of 18.071 mA cm⁻², V_OC of 1.4531 V, and FF of 78.08 %.

期刊介绍： The Journal of Physics and Chemistry of Solids is a well-established international medium for publication of archival research in condensed matter and materials sciences. Areas of interest broadly include experimental and theoretical research on electronic, magnetic, spectroscopic and structural properties as well as the statistical mechanics and thermodynamics of materials. The focus is on gaining physical and chemical insight into the properties and potential applications of condensed matter systems. Within the broad scope of the journal, beyond regular contributions, the editors have identified submissions in the following areas of physics and chemistry of solids to be of special current interest to the journal: Low-dimensional systems Exotic states of quantum electron matter including topological phases Energy conversion and storage Interfaces, nanoparticles and catalysts.
