报告摘要：

In this talk, I will go through some of the advances in the fundamental understanding of the loss mechanisms associated with charge photogeneration and charge transport phenomena in disordered solar cells. A technique which quantifies and selectively distinguish charge photogeneration and extraction, the processes that control the photocurrent output of the cell, has been used in conjunction with transient absorption spectroscopy, to separately determine the dynamics of the photocarrier process.

In the work to come, I will focus on the development of solution processed thin film solar cells. It seeks to apply next generation of materials to study key fundamental research challenge which will underpin this technological development. Furthermore, I will focus on combining and developing techniques, which will holistically probe charge generation, charge transport and optical properties of photovoltaic-based light sensitive organic diodes. The main aim of the work is to understand important aspects as an overall concept, namely their electro-optics in relation to molecular structure. Understanding how electrical and optical physics comes together in thin organic-semiconductor devices leads to significant advances in organic optoelectronic technology.

报告人简介：

Safa received her undergraduate and master’s degree, in Physics from University of Manchester (2005) and PhD from Imperial College London (2010). In 2010, she continued as a PDRA at Imperial College London. In 2013 she was awarded a grant from the British Engineering and Physical Research Council (EPSRC) to join National Physical Laboratory (U.K.), and in 2014 she moved to Australia as a post doctorate research fellow. In 2016 she was awarded with Sofja Kovolaveskja prize, from Alexander von Humboldt Foundation, which she is carrying out at University of Potsdam, Germany.

Her research interests involve the spectroscopy and photochemistry of conjugated organic materials and exploring their potential in photonic applications. Safa employs time-resolved absorption spectroscopy and charge transport techniques to elucidate relationships between the molecular structure of conjugated organic materials and parameters such as charge carrier lifetime, with the aim of improving the molecular design process for photonic devices.
