Organic solar cells face efficiency challenge due to slow current flow, researchers show

Researchers from the Chair of Optics and Photonics of Condensed Matter led by Prof. Dr. Carsten Deibel at the Chemnitz University of Technology and other partner institutions are currently working on solar cells made from novel organic semiconductors that can be produced using established printing processes. The scientists are collaborating interdisciplinarily to fundamentally understand these photovoltaic cells in order to further improve them.

Why printed organic solar cells lose power – and how to solve it

Organic solar cells—solar panels made from special carbon-based materials—offer an exciting future. They’re lightweight, flexible, and can be made quickly and cheaply using printing techniques, almost like printing a newspaper. But there’s one big problem: they aren’t as efficient as traditional silicon solar panels, and now scientists have figured out why. A team led by […] The post Why printed organic solar cells lose power – and how to solve …

Current research under the leadership of Chemnitz University of Technology contributes to a deeper understanding of why slow load carriers reduce efficiency

The research project aims to better understand the performance characteristics of organic solar cells.This creates new insights for the optimization of the printed cells.Organic solar cells can be produced simply and cheaply with printing methods. Compared to conventional cells made of crystalline silicon, however, the transport of the charge carriers generated by light into the organic solar cells is very slow. The reason for this is that the o…
