http://www.nature.com/news/cheap-solar-cells-tempt-businesses-1.15986 Some of us would be interested in solar cells panel discussion during one of our weekly Science Coffee Meetings. We have experts on board of ACT, for example Joao, Katharina, Ricarda, we could also invite somebody outside from the ACT specialized in ESTEC. It could be very interesting and informative meeting.
I just wanted to put another paper in this context: http://science.sciencemag.org/content/324/5923/63.short Solar cells based on Oxides, in particular BiFeO3. The key point here, is that while halide perovskites provide excellent efficiency, they only last a few hours because the material is very unstable. I learned this year about this oxide based materials exhibiting photovoltaic effect. The nice point of this materials is i) they are oxides, extremely stable and ii) are ferroelectrics, they have an internal polarization which would help in ionizing the photogenerated excitons even in the absence of pn junction.
