Optoelectronic devices interact with light and include LEDs and solar cells; my research program is focused on optoelectronic devices made using solution-processable materials. These include organic molecules and polymers, but also lead halide perovskites. Because they can be formulated into solution-based inks, they can be easily coated or printed; this makes device manufacture simpler and more scalable, reducing costs and energy inputs. My long-term vision is to advance organic and hybrid optoelectronic technologies from prototypes to commercial products. This proposal will bridge this gap and address issues related to upscaling through three short-term objectives: (i) develop the indophenine reaction for conjugated polymer synthesis; (ii) develop methods to control the film morphology of organic solar cells (OSCs) deposited by slot-die coating; and (iii) develop humidity-tolerant and shelf-stable inks for the slot-die coating of perovskite solar cells (PSCs). (i) Conjugated polymers via the indophenine reaction. A major barrier to the upscaling of organic electronics is the synthetic complexity of the materials. We will develop the indophenine reaction as a route to conjugated polymers. This would eliminate any need for transition metal catalysts or toxic trialkyltin reagents and significantly shorten syntheses, resulting in more scalable, cost-effective materials. (ii) Film morphology in slot-die coated OSCs. Spin coating is the de facto method of OSC fabrication but has little relevance industrially. We will develop sequential slot-die coating as a way of producing efficient OSCs and to adapt solvent vapor annealing into a scalable, online process to fine-tune the film morphology. In situ and operando UV/vis and x-ray scattering methodologies will be developed to assess and monitor changes in film morphology. (iii) Humidity-tolerant perovskite inks. The record efficiencies of PSCs have been achieved with the help of glovebox-integrated spin coaters, but environmental controls are often more difficult to achieve with more scalable coating methods. We seek to understand how environmental factors impact the performance of slot-die coated PSCs and to develop humidity-tolerant perovskite inks with long shelf lives. OSCs and PSCs promise to disrupt the solar industry, combining efficiency with rapid, scalable manufacturing processes, cost-effective materials, and shorter energy payback times. The wide-scale deployment of cheap, efficient solar modules would bolster efforts to reduce Canada's reliance on fossil fuels and fight climate change, while simultaneously generating new Canadian jobs in their manufacture and installation. But these benefits will only be realized if OSCs and PSCs can make the transition from laboratory prototypes to competitive commercial products. This proposal will bridge this gap and will help ensure that these environmental and socio-economic benefits become a reality.

光电设备与光相互作用，包括LED和太阳能电池；我的研究计划专注于使用解决方案处理材料制造的光电设备。这些包括有机分子和聚合物，还包括卤化物钙钛矿。因为可以将它们配合到基于溶液的油墨中，因此可以很容易地涂上或打印。这使设备制造更简单，更可扩展，从而降低成本和能源输入。我的长期视野是将有机和混合光电技术从原型到商业产品提高。该提议将弥合这一差距，并通过三个短期目标解决与升级有关的问题：（i）开发共轭聚合物合成的inindophenine反应； （ii）开发了控制通过插槽-DIE涂层沉积的有机太阳能电池（OSC）的膜形态的方法； （iii）为钙钛矿太阳能电池（PSC）的插槽涂层（PSC）开发耐湿性和固定型油墨。 （i）通过吲哚反应共轭聚合物。有机电子设备升级的主要障碍是材料的合成复杂性。我们将开发吲哚氨酸反应作为共轭聚合物的途径。这将消除对过渡金属催化剂或有毒试验二肽试剂的任何需求，并显着缩短合成，从而产生更可扩展，更具成本效益的材料。 （ii）在插槽涂层的OSC中的膜形态。自旋涂层是事实上的OSC制造方法，但工业上的相关性很小。我们将开发连续的插槽涂层，以作为产生有效的OSC的一种方式，并将溶剂蒸发调整为可扩展的在线过程，以微调膜形态。将开发原位和操作紫外线和X射线散射方法来评估和监测膜形态的变化。 （iii）耐湿性钙钛矿油墨。 PSC的创效率是在杂物箱集成的自旋涂料器的帮助下实现的，但是通过更可扩展的涂层方法，环境控制通常更难实现。我们试图了解环境因素如何影响老虎机涂层的PSC的性能，并开发具有较长货架寿命的耐湿性钙钛矿油墨。 OSC和PSC有望破坏太阳能行业，将效率与快速，可扩展的制造过程，具有成本效益的材料和较短的能源回报时间相结合。廉价，高效的太阳能模块的大规模部署将加强努力，以减少加拿大对化石燃料的依赖并打击气候变化，同时在其制造和安装中产生新的加拿大工作。但是，只有在OSC和PSC可以从实验室原型过渡到竞争性商业产品的过渡，才能实现这些好处。该提议将弥合这一差距，并将有助于确保这些环境和社会经济利益成为现实。
