個人簡歷：

Yulia Galagan is a Senior Scientist and Project Manager at TNO/Solliance (the Netherlands Organisation for applied scientific research). She received her Ph.D. in chemistry in 2002 from Kyiv University. During her PhD and the first few years of her research career she worked on the development of superconducting ceramics and polymer/ceramic composites. From 2005 till 2008 Dr. Galagan was employed as a research fellow at National Taiwan University, where she started her research in the field of organic and hybrid solar cells. In 2008 she joined TNO/Holst Centre. Her research interests are focused on organic and perovskite-based electronics (PVs, LEDs, sensors), from fundamental aspects to large area processing. Dr. Galagan has an expertise in the development of emerging materials for sustainable energy conversion, optoelectronics and bio-electronics with adjustable physical properties. Currently, Yulia Galagan is a group leader responsible for scale-up technologies for roll-to-roll manufacturing of perovskite photovoltaics.

演講摘要：

The history of modern solar cells starts in 1950s from the Bell Laboratory, when the first solar cells capable to convert sun energy into electricity were produced. From that time Photovoltaic (PV) technologies gained very rapid development. In the last few years PVs have evolved from the small-scale applications towards becoming a mainstream electricity source and one of the most promising sources of renewable energy. Although current PV systems can generate electricity in an efficient manner, techno-economic analysis of photovoltaic energy shows the necessity to reduce the manufacturing cost of PV systems. Emerging photovoltaic technologies attract a lot of attention due to their great potential for high power conversion efficiency (PCE), low cost and possibility of large-scale production using well-known roll-to-roll (R2R) printing and coating technologies.

The lecture will make an introduction into the history and the basic working principles of emerging photovoltaic technologies: dye synthesized, organic and perovskite solar cells. The main state-of-the-art achievements in the field will be demonstrated. Despite a significant research progress and high level of PCE, the technologies still did not reach the level of industrial manufacturing and commercialization. The main challenge today is how to move from lab scale devices to the devices manufactured on an industrial level. In order to fill the gap between the laboratory development and future industrial manufacturing, still a lot of research and developments are required. On the transition stage from “lab to fab”, a strong link between fundamental academic aspects and semi-industrial issues is observed. The most challenging issues related to the up-scaling will be highlighted in the lecture, and the possible solutions will be proposed. The progress in scaling up of organic and perovskite solar cells will be presented. Current research and developments in the field of emerging photovoltaics are aimed to satisfy three main requirements of commercialization: low cost, high efficiency, and high operational stability. The talk will show how the fundamental knowledge can contribute to answering global societal challenges such as the development of emerging renewable energy sources.
