Our research program is focused on the molecular engineering of novel organic materials for organic solar cell application (OSC). Organic Solar Cells (OSCs) have immense potential to unlock the power of the sun through the cost-effective direct conversion of sunlight into electricity. Governments in many jurisdictions have had to provide substantial financial incentives to facilitate the adoption of silicon-based solar cells, but this will not be necessary for commercial OSCs, which will be inexpensive and hence broadly accessible. OSCs can be fabricated onto light pieces of flexible plastic to produce a standalone cell, whose availability would allow ubiquitous supplemental power generation. They can also be integrated into the outer casings of devices such as laptop computers, iPods, and iPads to provide active recharging. Limitations in available organic materials are hampering the commercial introduction of OSCs. In our group we use the techniques of crystal engineering to control the solid state arrangement of the organic materials which comprise the OSC. Such control at the nanometer length scale is critical if OSCs are to see application and commercialization as it is only at this length scale that we can engineer and optimize the critical parameters of charge conduction and power conversion efficiency. We propose to continue our focus on a class of materials known as boron subphthalocyanines (BsubPcs). BsubPcs have ideal intrinsic molecular properties for OSC application. What remains is the need to engineer them into forms which have high charge conduction and good power conversion efficiencies. To accomplish these objectives, students within the program are expected to study at the intersection of the traditional disciplines of chemical engineering, applied chemistry, materials science and engineering, organic and inorganic chemistry, polymer chemistry, and physical chemistry.

我们的研究计划主要集中在有机太阳能电池应用（OSC）的新型有机材料的分子工程。有机太阳能电池（OSC）具有巨大的潜力，可以通过具有成本效益的直接将太阳光转化为电能来释放太阳能。许多司法管辖区的政府不得不提供大量的财政激励措施，以促进硅基太阳能电池的采用，但这对商业OSC来说并不必要，因为它价格低廉，因此可以广泛使用。OSC可以被制造在柔性塑料的轻块上以产生独立的电池，其可用性将允许无处不在的补充发电。它们还可以集成到笔记本电脑、iPod和iPad等设备的外壳中，以提供主动充电。可用有机材料的限制阻碍了OSC的商业引入。在我们的小组中，我们使用晶体工程的技术来控制有机材料的固态排列，其中包括OSC。如果OSC要看到应用和商业化，则在纳米长度尺度下的这种控制是至关重要的，因为只有在这种长度尺度下，我们才能设计和优化电荷传导和功率转换效率的关键参数。我们建议继续关注一类称为硼亚酞菁（BsubPcs）的材料。BsubPcs具有理想的OSC应用的固有分子性质。剩下的是需要将它们设计成具有高电荷传导和良好功率转换效率的形式。为了实现这些目标，该计划的学生预计将在化学工程，应用化学，材料科学与工程，有机和无机化学，高分子化学和物理化学的传统学科的交叉点学习。
