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了一项多学科研究计划。我程序的重点是将独特的有机材料纳入可持续能源设备的分子设计，纳米工程和整合。目标应用是有机太阳能电池。有机太阳能电池是基于有机材料的能量产生设备，可通过零碳足迹的过程促进阳光转化为电流。向前迈进，我们将继续以多种方式扩展这一调查途径。 特定的感兴趣材料是邻苯烷及其类似物。邻苯烷烷是已知的染料和颜料，这些染料和色素不断作为功能性有机电子材料出现。我们将继续探索硼亚脑酸（BSUBPC），它们是与邻苯烷烷的环形类似物，以利用其特性，其中包括：强烈的光吸收，可捕获约39％的阳光；高电荷电导率和多功能性；以及促进单线裂变过程的能力，该过程能够每光子从太阳吸收的光中产生两个电子/电荷。 我们最近显示，在多伦多市中心的外部环境环境中，基于BSUBPC的有机太阳能电池非常稳定。在这种环境中，我们将继续自行评估所有新材料，并与BSUBPC配对，以了解分子结构与环境稳定性之间的关系。 我们的初步结果表明，称为四苯甲苯甲酸（TBC）的额外的环收缩的邻苯二甲胺类似物在有机太阳能电池中也具有相似的所需性能和功能。这包括捕获剩余〜61％阳光的能力，可能通过我们称为免费吸收工程的黑色“太阳能电池”（CAE）产生黑色的“太阳能电池”（CAE）。我们建议扩大可以与BSUBPC配对的环的合同类似物的研究，并能够吸收高能量蓝色，并从太阳光谱中吸收高能红色/近红外光子，目的是产生黑色的太阳能电池。 我们还将通过将用于将BSUBPC掺入有机太阳能电池和配对材料的溶液打印的真空沉积方法结合使用，研究有机太阳能电池制造技术。这将使我们能够在识别出高度稳定的材料（例如BSUBPC）之后考虑一种最佳的设备制造方法；与设计针对特定制造方法的材料相反。 我们还将将程序扩展到红外传感器和有机电池中。有机电池是可持续的能源存储设备，具有最小的碳足迹，并且完全缺乏与锂离子电池相关的易燃性危害。
