NPT Purdue Center e-Workshop: Morphology- Aware Design and Performance Limits of Organic Solar Cells
Host: Bob Havemann Date: Thursday, November 17, 2011 Time: 6:00 pm, Eastern Standard Time (New York, GMT-05:00) Session number: 642 737 747
NPT Center Student Presenter: Biswajit Ray
Biography: Biswajit Ray is a PhD student in the school of Electrical and Computer Engineering, Purdue University, West Lafayette, Indiana. He works with Prof. Muhammad Ashraf Alam in the area of organic solar cell. Before joining Purdue he did Masters from Indian Institute of Science, Bangalore, India in 2008 and Bachelors in Electrical and Electronics Engineering from National Institute of Technology, Trichy, India in 2006.
Abstract: Organic photovoltaic (OPV) technology is currently a topic of great interest for potentially low cost solar energy conversion and possibility of many novel portable as well as building integrated PV applications. Successful commercialization of this technology, however, will require significant improvement in efficiency and lifetime. In the last few years, a series of breakthroughs in developing novel polymers have raised the efficiency of OPV exceeding 8%. Further improvement in performance relies on process optimization and better device design, which requires profound understanding of the physics of device operation. Unlike conventional solar cells (Crystalline Si, CIGS, CZTS, etc.), active layer morphology of an OPV cell is very complex and the classical theory does not apply. However, understanding of the OPV morphology is important because morphology in organic solar cell not only dictates its performance but also its lifetime.
In this talk, I will present a theoretical framework which explicitly relates the OPV morphology to its performance and optimizes the fabrication conditions for higher efficiency/lifetime. I will also explain the geometry-specific performance limits of various solar cell parameters and predict the intrinsic lifetime of the cell in terms of the material constants. Finally, I will illustrate few novel device concepts, which can potentially improve the efficiency and lifetime of OPV cells.
