Towards printed and stable organic photovoltaics from non-fullerene acceptors

After reaching close to 20% single junction performance, the next major challenge for organic photovoltaics (OPV) is to develop mass production technologies for low-energy, high-throughput processing of stable devices.

Scope:

The Scientific Symposium "Towards printed and stable organic photovoltaics from non-fullerene acceptors" brings together experts in the field to discuss the latest advancements in greener production, improved performance, and stability of organic photovoltaics (OPV) with the goal of fostering industrialization and mass adoption. The symposium will focus on third generation solar cells based on organic semiconductors, particularly those utilizing non-fullerene acceptors and high-performance organic light harvesting materials from a broad range of interdisciplinary aspects.

Key topics of discussion will include the development of mass production techniques for low-energy, high-throughput OPV processing to reduce environmental impact, as well as advances in ambient processing of OPV devices using non-halogenated solvents. The symposium will also cover all-printed device layouts that replace scarce materials with sustainable alternatives without compromising device performance.

Furthermore, the symposium will explore breakthrough strategies that are based on fundamental research – from various disciplines from chemistry over physics to engineering – to enhance device stability and improve the efficiency of printed organic solar cells. The scope also includes single-component materials, stable transport layers, cost-efficient high-throughput experimentation approaches, robot and artificial intelligence-supported workflows, as well as experiments and modelling of the active layer morphology, device simulations, and fundamental approaches such as analytic modelling of charge transport and recombination. Applications of OPV in various form factors, such as building-integrated systems or agrivoltaics, will be discussed. This symposium addresses academia as well as industry.

Overall, the symposium aims to accelerate the development and deployment of printed organic solar cells through collaboration and innovation in order to achieve competitive market entry.

Hot topics to be covered by the symposium:

  • stable and efficient donor, acceptor, and single-component materials for OPV devices
  • stable, conductive transport layers
  • advanced deposition processes by coating and printing
  • ambient air processing from non-halogenated solvents
  • structure and morphology of the active layer of printed organic solar cells
  • device physics by advanced experiments, modelling and simulations
  • high-throughput characterization and materials discovery by machine learning
  • thermal and photo stability of materials and devices
  • device integration and complex device architectures (e.g. tandems)
