Abstract

This study investigates the photovoltaic (PV) properties, their energetic offset correlations of quinazoline-based push-pull switches. It finds an interesting correlation between their band-gaps and the rotational velocities with a linear fit value of 0.78. Also, their larger positive offsets up to 10¹¹ by their open circuit voltage (V_oc) tend to facilitated their efficient electron injection, leading to an improved photocurrent generation for device performance. Through push-pull phenomenon, a highest λ_max of 574 nm was attained for the dye T5. Their PV performance of the was calculated as V_oc, short circuit current (J_sc), and light harvesting efficiency (LHE) as 0.05–0.81 eV, 28.52–40.10 mA/cm² and 0.65–0.87 respectively. Their transition density matrix (TDM) maps showed an enhancement of electron injection with the use of a more intense electron acceptor. This study advances understanding of the PV properties of quinazoline-based switches for developing PV devices. Their further research can lead to high-performance PV systems.

基于长距离推挽的近红外开关和光伏优化作为能量补偿的新型喹唑啉锚定染料研究设计

本文研究了基于喹唑啉的推挽开关的光伏(PV)特性及其能量偏移相关性。它发现它们的带隙与转速之间存在有趣的相关性，线性拟合值为0.78。此外，由于开路电压(Voc)，它们的正偏移量高达1011，这有利于它们有效的电子注入，从而改善了器件性能的光电流产生。通过推挽现象，染料T5的λmax最高可达574 nm。其光伏性能分别为Voc 0.05 ~ 0.81 eV，短路电流(Jsc) 28.52 ~ 40.10 mA/cm2和LHE (LHE) 0.65 ~ 0.87。它们的跃迁密度矩阵(TDM)图显示，使用更强的电子受体可以增强电子注入。这项研究促进了对喹唑啉基开关的PV特性的理解，为开发PV器件提供了基础。他们进一步的研究可以带来高性能的光伏系统。
