This project will produce manufacturable nanoscale architectures for heterojunction solar cells. Though routed strongly within 'science', the objectives are to achieve engineering solutions to allow the breakthrough needed in this field (target efficiency 10%). Excitonic solar cells based on molecular semiconductors require the presence of a heterojunction between electron and hole-accepting semiconductors in order to separate charges from photogenerated excitons. Large heterojunction interfacial areas are required if all photogenerated excitons are to reach the heterojunction before decaying, and this requires a complex nanoscale architecture. Current methods to achieve this nanostructure and limited and solar cell performance of such devices has stalled. We propose therefore to develop generic routes to separate the control of the nanoscale morphology from the selection of the donor and acceptor semiconductors. This will represent a critical advance in allowing a stable process window, and should allow improved photovoltaic performance through better morphology control and the ability to use semiconductors better matched to the solar spectrum. These routes will be compatible with low temperature processing (this is critical for low-cost manufacturing). The general principle we will use is to separate the processes needed to form the desired nanoscale architecture from the subsequent formation of the active semiconductor-semiconductor heterojunctions at which charge separation is achieved.Central to our approach is the use of 'sacrificial' polymer structures that provide excellent control of nanoscale morphology, and their later replacement with active semiconductors. We will use the controlled nanoscale structures produced using di-block copolymers

该项目将为异质结太阳能电池生产可制造的纳米级架构。虽然在“科学”中有很强的路线，但目标是实现工程解决方案，以实现该领域所需的突破（目标效率10%）。基于分子半导体的激子太阳能电池需要在电子和空穴接受半导体之间存在异质结，以便将电荷与光生激子分离。如果所有光生激子在衰减之前到达异质结，则需要大的异质结界面面积，并且这需要复杂的纳米级结构。目前实现这种纳米结构和有限的太阳能电池性能的方法已经停滞。因此，我们建议开发通用的路线，以分离的供体和受体半导体的选择的纳米级形态的控制。这将代表允许稳定工艺窗口的关键进步，并且应该通过更好的形态控制和使用与太阳光谱更好匹配的半导体的能力来改善光伏性能。这些路线将与低温处理兼容（这对低成本制造至关重要）。我们将使用的一般原则是分离的过程中需要形成所需的纳米级架构，从随后形成的有源半导体异质结，在其中实现电荷分离。我们的方法的核心是使用“牺牲”聚合物结构，提供了良好的控制纳米级形态，和他们后来的有源半导体替代。我们将使用由二嵌段共聚物制成的可控纳米级结构
