I lead a multidisciplinary research program in the Department of Chemical Engineering and Applied Chemistry at the University of Toronto. The focus of my program is the molecular design, nano-engineering and integration of unique organic materials into sustainable energy devices. The target application has been organic solar cells. Organic solar cells are energy generation devices based on organic materials that facilitate the conversion of sunlight into electrical current through a process with zero carbon footprint. Moving forward we will continue to expand this investigative path in several ways. *** A specific class of materials of interest are phthalocyanines and their analogs. Phthalocyanines are known dyes and pigments that have continually emerged as functional organic electronic materials. We will continue to explore boron subphthalocyanines (BsubPcs) which are ring contracted analogs to phthalocyanines to exploit their properties which include: strong light absorption that enables the capture of ~39% of sunlight; high charge conductivity and multifunctionality; and the ability to facilitate the process of singlet fission, a process that enables the generation of two electrons/electrical charges per photon of light absorbed from the sun.*** We have recently shown our BsubPc based organic solar cells are very stable in the outside ambient environment of downtown Toronto. We will continue to assess all new materials, on their own and paired with BsubPcs, in this environment to understand the relationship between molecular structure and environmental stability.*** We have preliminary results that show an additional ring contracted phthalocyanine analogs known as tetrabenzocorrole (Tbc) also have similar desired properties and functionality within organic solar cells. This includes the ability to capture the remaining ~61% of sunlight, potentially yielding a ‘black' solar cell through what we call ‘complimentary absorption engineering' (CAE). We propose to expand the investigation of ring contracted analogs that can be paired with BsubPcs and enable the absorption of high energy blue and lower energy red/near infrared photons from the sun spectrum with the goal of producing a ‘black' solar cell.*** We will also investigate organic solar cell manufacturing techniques by combining the vacuum deposition method used for incorporating BsubPcs into organic solar cells and the solution printing of paired materials. This will enable us to consider an optimal device manufacturing method after identifying highly stable materials such as BsubPcs; in contrast to designing materials around targeting particular manufacturing methodologies.*** We will also expand our program into infrared sensors and organic batteries. Organic batteries are sustainable energy storage devices with minimal carbon footprint and complete lack of flammability hazard associated with lithium ion batteries.

我在多伦多大学化学工程和应用化学系领导一个多学科研究项目，该项目的重点是分子设计、纳米工程以及将独特的有机材料集成到可持续能源设备中。有机太阳能电池是基于有机材料的能源发电装置，可通过零碳足迹的过程将阳光转化为电流*** A。感兴趣的特定类别材料是酞菁及其类似物是已知的染料和颜料，作为功能性有机电子材料不断出现。我们将继续探索硼亚酞菁 (BsubPcs)，它是酞菁的缩环类似物，以开发其特性，包括： 强光吸收。捕获约 39% 的阳光；高电荷传导性和多功能性；以及促进单态裂变过程的能力；从太阳吸收的光的每个光子有两个电子/电荷。*** 我们最近展示了我们基于 BsubPc 的有机太阳能电池在多伦多市中心的外部环境中非常稳定。我们将继续评估所有新材料。他们自己的并与 BsubPcs 配对，在这种环境中了解分子结构和环境稳定性之间的关系。*** 我们的初步结果表明，另一种称为四苯并咔咯 (Tbc) 的环收缩酞菁类似物也具有类似的所需特性，并且这包括捕获剩余约 61% 阳光的能力，通过我们所谓的“互补吸收工程”(CAE) 可能会产生“黑色”太阳能电池。我们建议扩大对环收缩的研究。可与 BsubPcs 配对的类似物，能够吸收太阳光谱中的高能蓝光和低能红光/近红外光子，目标是生产“黑色”太阳能电池。*** 我们还将研究有机太阳能电池的制造技术通过结合用于将 BsubPcs 融入有机太阳能电池的真空沉积方法以及配对材料的溶液印刷，这将使我们能够在确定 BsubPcs 等高度稳定的材料后考虑最佳的器件制造方法，而不是围绕特定的制造方法来设计材料。 *** 我们还将把我们的计划扩展到红外传感器和有机电池。有机电池是可持续的能源存储设备，具有最小的碳足迹，并且完全没有与锂离子电池相关的易燃危险。
