Advances in hybrid solar cells: From hybrid organic/inorganic to perovskite photovoltaics — •Lukas Schmidt-Mende — University of Konstanz

In this presentation we will discuss the path from solid-state dye sensitized solar cells over extremely thin absorber cells towards perovskite solar cells. Hybrid solar cells have been investigated for some time and a lot of knowledge gained in this field has helped to increase the power conversion efficiencies of recently discovered perovskite solar cells from 2.2% when first reported in 2006 to over 20% in 2014. Going from liquid electrolyte cells to solid-state hybrid solar cell architecture had a major influence on this performance step. Many structures previously used in hybrid solar cells have been now implemented very successfully in perovskite solar cells. We will give some examples of such knowledge transfer from conventional hybrid solar cells to perovskite solar cells. A discussion of the similarities as well as the differences of the described solar cell types will help to understand possible limitations.
