Decarbonized energy and sustainability

B

Advancing sustainable organic photovoltaics: from experiments and materials to applications and device models


As per the recently approved European Green Deal, electricity supply models must transition toward decarbonized and sustainable energy harvesting technologies. Printed electronics energy solutions such as organic photovoltaics (OPV) are promising to maximize the energy return on investment at lower cost and with uncompromised sustainability.

Scope:

The present symposium gathers the latest breakthrough advances in printed OPV toward its greener production, improved performance and stability, to ultimately foster its industrialization and mass adoption by the civil society. Accordingly, the introduction of novel organic light harvesting materials with high performance and facile synthesis will be of utmost importance together with the improved understanding of their device physics and photophysics supported by experiments and simulation approaches. On the other hand, advances in ambient processing of sustainable OPV devices from non-halogenated solvents (including both active layer and interlayer ink formulations) are warmly welcome in this symposium to bridge the lab-to-fab gap. Special attention will be raised to all-printed device layouts where scarce materials such as indium (as part of the workhorse indium tin oxide) are replaced by sustainable alternatives with uncompromised device performance. Resources- and cost-efficient high-throughput experimentation approaches in which humans, robots and/or artificial intelligence are orchestrated in a single workflow will be covered as a more sustainable and convenient route toward accelerated OPV research providing predictive capability. Breakthrough strategies to improve the understanding and enhance the device stability are also key to advance printed OPV to competitive market entry thresholds in terms of cost per watt peak, and they will be accordingly revisited in this symposium. Finally, models and applications of OPV in indoor and outdoor building-integrated form factors (internet-of-things sensors, smart windows, agrivoltaics) will be presented. In this regard, the symposium welcomes novel device structures such as fully organic and hybrid (OPV/perovskite, OPV/silicon) tandem layouts.

Hot topics to be covered by the symposium:

  • Novel light harvesting materials development
  • Device physics and photophysics
  • Theory and novel simulation approaches
  • Air processing of sustainable OPV via green solvents
  • High-throughput experimentation and machine-learning for materials discovery
  • Device photo- and thermal stability enhancements
  • Building-integrated OPV: indoors, smart windows, agrivoltaics
  • Novel device structures (OPV tandems, OPV/perovskite, OPV/silicon)
