Energy remains one of the great challenges for the world. There is a considerable interest in developing renewable energy resources and improving the technologies for energy conversion. In this context, solar energy is a source with the proven capacity to meet the increasing global energy needs. In recent years, efficient organic solar cells (OSCs) have been fabricated using organic polymers and small molecules. Metalated conjugated organic molecules have also been shown to be good alternatives to the all-organic congeners and have demonstrated good promise as solar cell materials in OSCs and dye-sensitized solar cells (DSSCs). Among these, soluble molecular/polymeric metallaynes and their acetylide-functionalized metalloporphyrins show promising results in much of these investigations with the best power conversion efficiencies of 9.06% (for single-layer OSC), 12.5% (for tandem OSC) and 13.2% (for co-sensitized DSSC) to date. This review summarizes the recent advances of this field. Various factors influencing the device performance such as the nature of metal center and organic spacer, absorption coefficient, bandgap energy, charge carrier mobility, accessibility of triplet excitons and blend film morphology of these materials will be discussed. Given the diversity of transition metals available (for example, Pt, Zn, Ru) and structural versatility of the organic components, it is anticipated that this nascent field using metalated organic materials would continue to lead to exciting prospects in the near future.

分子/聚合金属烯和相关分子:太阳能电池材料和设备

能源仍然是世界面临的巨大挑战之一。开发可再生能源和改进能源转换技术引起了极大的兴趣。在这种情况下,太阳能是一种经证实具有满足日益增长的全球能源需求的能力的来源。近年来,已经使用有机聚合物和小分子制造了有效的有机太阳能电池(OSC)。金属化的共轭有机分子也已被证明是全有机同源物的良好替代品,并已被证明是OSC和染料敏化太阳能电池(DSSC)中太阳能电池材料的良好前景。在这些研究中,可溶性分子/聚合金属烯及其乙炔官能化的金属卟啉在许多研究中均显示出令人鼓舞的结果,其最佳功率转换效率为9。迄今为止,分别为06%(对于单层OSC),12.5%(对于串联OSC)和13.2%(对于共敏化DSSC)。这篇综述总结了该领域的最新进展。将讨论影响器件性能的各种因素,例如金属中心和有机间隔物的性质,吸收系数,带隙能量,电荷载流子迁移率,三重态激子的可及性以及这些材料的混合膜形态。考虑到可用的过渡金属的多样性(例如Pt,Zn,Ru)和有机组分的结构通用性,可以预见,这种使用金属化有机材料的新兴领域将在不久的将来继续带来令人兴奋的前景。将讨论影响器件性能的各种因素,例如金属中心和有机间隔物的性质,吸收系数,带隙能量,电荷载流子迁移率,三重态激子的可及性以及这些材料的混合膜形态。考虑到可用的过渡金属的多样性(例如Pt,Zn,Ru)和有机组分的结构通用性,可以预见,这种使用金属化有机材料的新兴领域将在不久的将来继续带来令人兴奋的前景。将讨论影响器件性能的各种因素,例如金属中心和有机间隔物的性质,吸收系数,带隙能量,电荷载流子迁移率,三重态激子的可及性以及这些材料的混合膜形态。考虑到可用的过渡金属的多样性(例如Pt,Zn,Ru)和有机组分的结构通用性,可以预见,这种使用金属化有机材料的新兴领域将在不久的将来继续带来令人兴奋的前景。
