题目：Organic Solar Cells and the Energy Challenge
星期一下午2：30，A722会议室
主持：陈立桅

摘要： Organic solar cells potentially offer a low cost, large area,
flexible, light-weight, clean, and quiet alternative energy source for
indoor and outdoor applications. However, power conversion efficiencies
and operational lifetimes of these devices are still low for use in any
practical application. Our research in this area focuses on controlling
material processing conditions and designing/synthesizing materials having
a broad absorption spectrum and high charge carrier mobility. In parallel
with materials synthesis and processing, we have developed
characterization techniques to probe film morphology, to image the
donor-acceptor networks laterally and vertically, to assign phase domains
to the donor and the acceptor components, and to study nanoscale charge
generation and transport in organic solar cells. From an overall
perspective, these studies tackle fundamental critical problems associated
with emerging organic semiconductor based technologies that generate energy.
