Increasing energy demands and environmental concerns about global warming have led to a greater focus on the development of renewable energy sources. Dye-sensitized solar cells (DSSCs) have attracted considerable attention in recent years as they offer the possibility of low-cost conversion of photovoltaic energy. In particular, triarylamine functionalized organic photosensitizers show high molar absorption coefficients in the visible spectral region, good dye aggregation resistance and reliable electrochemical and thermal stabilities. This review emphasizes the recent developments and strategies employed in the structural design of arylamine-based metallated and metal-free organic photosensitizers. The influences of molecular structural engineering on photophysical and electrochemical properties along with photovoltaic parameters and the efficiency of DSSCs are presented. Hence, by drawing a correlation among the structures of arylamine-derived photosensitizers, their properties and photovoltaic parameters of DSSCs, it will be useful in optimizing new dyes for the generation of efficient photovoltaic cells for energy production.

日益增长的能源需求和对全球变暖的环境关注已导致人们更加关注可再生能源的发展。染料敏化太阳能电池（DSSC）近年来引起了相当大的关注，因为它们提供了光伏能源低成本转换的可能性。特别地，三芳基胺官能化的有机光敏剂在可见光谱区域中显示出高摩尔吸收系数，良好的抗染料聚集性以及可靠的电化学和热稳定性。这篇综述强调了芳基胺基金属化和不含金属的有机光敏剂在结构设计中采用的最新发展和策略。提出了分子结构工程对光物理和电化学性质以及光伏参数和DSSCs效率的影响。因此，通过在芳基胺衍生的光敏剂的结构，其性质和DSSC的光伏参数之间建立关联，将有助于优化新型染料，以产生用于产生能量的有效光伏电池。
