The worldwide demand for low cost and clean energy sources has never been greater and is continuously growing as it scales with population increase. To address this challenge and reduce the environmental impact of fossil fuel consumption, it is crucial to harvest energy from alternative sources, especially the sun. Conversion of sunlight into electricity is achieved by the photovoltaic (PV) process. However, to meet future PV power requirements novel device concepts and ultimately new material systems are needed. New approaches for solar energy conversion include organic PV cells (OPVs) that are characterized by low cost. Although the power conversion efficiency of OSCs is still considerably below what is attainable by inorganic semiconductor-based counterparts, other desirable characteristics, such as flexibility and low weight, make them ideal for specific niche applications, such as integration into buildings and satellites. In these OPV devices, PV conversion is based on the separation of photogenerated charges at an interface between electron donor and acceptor materials, which imposes some constraints on the photoactive layer of the cells. We propose a promising new direction to improve the active layer morphology and cell efficiency by the incorporation of highly anisotropic structures such as carbon nanotubes (CNTs), which may facilitate charge transport to the electrodes. We aim to investigate the insertion of carbon nanomaterials (CNTs and graphene), in collaboration with our industrial partners, Raymor Nanotech and MPB technologies Inc., with light sensitive organic conjugated polymers, by creating a high efficiency hybrid OPV system. Our long term objective is the development of advanced concepts for the integration of such nanomaterials into commercial devices for solar energy conversion. This project will also contribute to the training of Highly Qualified Personnel.

世界范围内对低成本和清洁能源的需求从未如此之大，并且随着人口的增长而不断增长。为了应对这一挑战并减少化石燃料消耗对环境的影响，从替代能源，特别是太阳能中获取能源至关重要。太阳光转化为电能是通过光伏（PV）过程实现的。然而，为了满足未来的光伏发电需求，需要新的器件概念和最终的新材料系统。用于太阳能转换的新方法包括以低成本为特征的有机PV电池（OPV）。 虽然OSC的功率转换效率仍然大大低于基于无机半导体的对应物所能达到的效率，但其他理想的特性，如灵活性和低重量，使它们成为特定利基应用的理想选择，如集成到建筑物和卫星中。在这些OPV器件中，PV转换基于在电子供体和受体材料之间的界面处光生电荷的分离，这对电池的光活性层施加了一些约束。我们提出了一个很有前途的新方向，以改善活性层的形态和电池效率的高度各向异性的结构，如碳纳米管（CNT），这可能有助于电荷传输到电极。 我们的目标是研究碳纳米材料（CNT和石墨烯）的插入，与我们的工业合作伙伴，Raymor Nanotech和MPB technologies Inc.，与光敏有机共轭聚合物，通过创建一个高效率的混合OPV系统。我们的长期目标是开发先进的概念，将这种纳米材料集成到太阳能转换的商业设备中。该项目还将有助于培养高素质的人才。
