Our research program is based in the field of materials chemistry and has a specific focus on the development of organic electronic devices. These novel devices exist at the interface of conventional electronics and materials chemistry and are the result of revolutionary advances in small molecule and plastic semiconductors. They can be used to manufacture exciting new consumer goods such as flexible, low-cost plastic solar cells and bendable flat panel displays. Specifically, the goal of our research program is to develop highly efficient and long-lived solar cells based on organic materials. The advantage of these organic solar cells is that they can be prepared and processed much more cheaply than conventional silicon-based photovoltaic devices. Their ease and economy of manufacture reduces the overall cost associated with complete photovoltaic modules, and it is hoped that this will lead to more wide-spread adoption of this emerging green technology. In order to make organic solar cells more efficient, we need to better understand and optimize the function of each part of the device. In the first part of our work, we intend to focus on maximizing the amount of incident light that can be effectively utilized by the device. This will be accomplished by the use of special light trapping nanostructures that ensure sunlight stays locked within the solar cell, where it will eventually be absorbed and converted into electrical energy. We also intend to develop new interfacial layers for use within the cell. These layers act as bridges between different parts of the photovoltaic device, helping each of the components function together as a unit. Finally, we will pursue the development of new inorganic/organic hybrid solar cells. These unique devices combine the excellent electrical properties of metal oxides with the unique properties of organic semiconductors. Synchrotron X-ray techniques available at the Canadian Light Source will be used to probe the molecular structure of these devices and to help identify ways of improving their power conversion efficiency.

我们的研究计划是基于材料化学领域，并特别关注有机电子器件的开发。这些新型器件存在于传统电子学和材料化学的界面上，是小分子和塑料半导体革命性进展的结果。它们可用于制造令人兴奋的新型消费品，如柔性、低成本的塑料太阳能电池和可弯曲的平板显示器。具体而言，我们研究计划的目标是开发基于有机材料的高效和长寿命太阳能电池。这些有机太阳能电池的优点是，它们的制备和加工成本比传统的硅基光伏器件低得多。其制造的简易性和经济性降低了与完整光伏模块相关的总成本，并且希望这将导致更广泛地采用这种新兴的绿色技术。 为了使有机太阳能电池更高效，我们需要更好地了解和优化器件各部分的功能。在我们工作的第一部分，我们打算专注于最大限度地提高设备可以有效利用的入射光的量。这将通过使用特殊的光捕获纳米结构来实现，该纳米结构确保阳光保持锁定在太阳能电池内，最终将被吸收并转化为电能。我们还打算开发新的界面层用于电池内。这些层充当光伏器件不同部分之间的桥梁，帮助每个组件作为一个单元一起工作。最后，我们将继续开发新型无机/有机混合太阳能电池。这些独特的器件联合收割机结合了金属氧化物的优良电性能和有机半导体的独特性能。加拿大光源提供的同步加速器X射线技术将用于探测这些设备的分子结构，并帮助确定提高其功率转换效率的方法。
