Exotic materials and innovative concepts for photovoltaics

The success story of hybrid perovskite solar cells confirms that research on novel photovoltaic materials can produce outstanding breakthroughs. This clearly strongly supports the organization of an E-MRS symposium on novel and emerging materials and concepts for photovoltaics which will serve to make E-MRS a leader in the world in new energy materials.


This symposium will address fundamental and applied research on innovative photovoltaics materials and device integration. The focus will be on non-conventional photovoltaics, or conventional photovoltaics but with a radically new approach. Novel materials such as exotic silicon, oxides or multinary compounds, novel organic/inorganic materials will be included. It should be noted that inorganic perovskites have reached a conversion efficiency of 14.3% in 2020 (CsPbI3). All third generation and emerging concepts such as multiple carrier generation, hot carrier and intermediate band solar cells, upconversion and downconversion are of increasing relevance and will be discussed. Novel experimental synthesis and characterization techniques are of interest in this symposium. Novel contacting and packaging approaches are also of interest.  Theoretical calculations of novel materials or emerging concepts are also relevant. Theoretical approaches on novel absorbers and concepts are fundamental to give directions to experimentalists in the field of photovoltaics.

Hot topics to be covered by the symposium:

  • Emerging solar cell absorbers
  • Computational design of novel materials or concepts
