The ability for organic materials to behave as conductors and semiconductors has ushered in an entire new era of advanced electronics that has dramatically changed our society. The key advantages over traditional inorganic materials such as silicon are: 1) the structure of the organic materials can be easily modified using synthetic chemistry allowing for precise control over the materials optoelectronic and physical properties allowing for tailored device function and 2) the organic materials are easily processed into electronically active solids (films) via low temperature methods such as printing or sublimation allowing for additive manufacturing. Applications include light emitting diodes, batteries, sensors, medical imaging, transistors, and photovoltaics (PV). The proposed research program will advance organic solar cell (OSC) technology through materials innovation, new chemistry, and device fabrication from lab to prototype scale. OSCs are a promising clean-energy technology. OSCs rely on organic materials for converting photon energy into electricity. Active materials are soluble in organic solvents allowing for printing. This enables the fabrication of OSCs onto a range of substrates/surfaces including foils and plastic films that are lightweight and flexible. OSCs can be color-tuned and made semi-transparent, thus the type and amount of transmitted light can be finely adjusted. Their organic nature opens the possibility of fully-disposable devices. Unfortunately, to date OSCs have not been widely adopted owing to the reduction in price of silicon-based solar cells. Alternatively, OSCs have utility in niche applications such as solar windows, indoor PV, wearable PV, greenhouse PV, decorative PV, and personal portable charging devices. This research program will center on the development of single photoactive material OSCs, the next frontier in organic PV research. The scientific approach will involve new molecular designs based upon non-fullerene acceptors, new synthetic strategies that are both sustainable and versatile, systematic evaluation of structure-property-function relationships using a range of optoelectronic and nanoscale characterization, and device performance. Champion materials will be vetted in fully printed OSC modules to validate their potential for practical applications. A key objective is to gain a fundamental understanding of materials self-assembly and to translate this knowledge into top performance. Success of this research program will result in the training of HQP in a interdisciplinary field of study, Canadian owned intellectual property in the emerging field of printed electronics and alternative solar power, scientific advancements disseminated in refereed journal publications, clear guidelines on how to develop next generation materials and processes for advanced energy and electronic applications, and advancements in additive-manufacturing to ensure sustainable technology production in Canada.

有机材料作为导体和半导体的能力开创了一个全新的先进电子时代，极大地改变了我们的社会。与传统无机材料（如硅）相比，其主要优势在于：1）有机材料的结构可以使用合成化学容易地改性，允许精确控制材料的光电和物理性质，允许定制的器件功能，和2）有机材料容易地加工成电子活性固体（膜）。通过低温方法，例如允许增材制造的印刷或升华。应用包括发光二极管、电池、传感器、医学成像、晶体管和光电子器件（PV）。拟议的研究计划将通过材料创新，新化学和从实验室到原型规模的设备制造来推进有机太阳能电池（OSC）技术。 OSCs是一种很有前途的清洁能源技术。OSC依靠有机材料将光子能量转换为电能。活性材料可溶于有机溶剂，允许印刷。这使得能够将OSC制造到一系列基底/表面上，包括重量轻且柔性的箔和塑料膜。OSC可以进行颜色调节并制成半透明的，因此可以精细地调节透射光的类型和量。它们的有机性质开启了完全一次性设备的可能性。不幸的是，由于硅基太阳能电池价格的降低，迄今为止OSC尚未被广泛采用。可替代地，OSC在诸如太阳能窗、室内PV、可穿戴PV、温室PV、装饰PV和个人便携式充电装置的利基应用中具有实用性。 该研究计划将集中在单一光活性材料OSC的开发上，这是有机光伏研究的下一个前沿。科学方法将涉及基于非富勒烯受体的新分子设计，可持续和多功能的新合成策略，使用一系列光电和纳米级表征以及器件性能对结构-性能-功能关系进行系统评估。冠军材料将在完全印刷的OSC模块中进行审查，以验证其实际应用的潜力。一个关键目标是获得材料自组装的基本理解，并将这些知识转化为最佳性能。 该研究计划的成功将导致HQP在跨学科研究领域的培训，加拿大在印刷电子和替代太阳能的新兴领域拥有的知识产权，在参考期刊出版物中传播的科学进步，关于如何开发下一代材料和先进能源和电子应用程序的明确指导方针，以及增材制造的进步，以确保加拿大的可持续技术生产。
