| Description: | [DCS seminar] Dr. Monojit Bag (Research Associate, University of Massachusetts, Amherst, USA,) -- Organic and organic/inorganic hybrid electronics: A new generation solar cells. |
| Date: | Wednesday, Jun 10, 2015 |
| Time: | 4 p.m. - 5:30 p.m. |
| Venue: | G05, Lecture Hall Complex |
| Details: | In last three decades we have observed a stiff growth in organic electronics especially in display, sensors, memory and power applications. In this talk I will touch upon some applications in bioelectronics and imaging. A simple structure, polymer/electrolyte interface can be used as artificial retina device as well as single pixel multi-color sensors. Second part of my talk is related to the power application. I will discuss about major roadblock for fabricating large-scale organic/polymer bulk hetero-junction solar cells and our approach to solve these problems. We have demonstrated polymer nanoparticle approach to control active layer morphology at multiple length-scale. This approach also introduces aqueous-based ink for eco-friendly fabrication of organic solar cells. In the end I will talk about new generation organic-inorganic perovskite solar cells. Despite high efficiency one of the major concern in perovskite solar cell is photo-stability. We have proposed a possible pathway of photo-induced degradation, which can be prevented by reducing ion transport through lead tri-halide octahedra. I will also talk about how to improve power conversion efficiency by interface engineering, and perovskite/polymer tandem solar cells approach. |
