(Source: Max-Planck-Gesellschaft zur Förderung der Wissenschaften eV) New insights into working mechanism indicate how novel perovskite solar cells can be further optimised October 01, 2014 Conventional silicon solar cells could have an inexpensive competitor in the near future. Researchers from the Max Planck Institute for Polymer Research in Mainz, together with scientists from Switzerland and Spain, have examined the working principle of an innovative type of solar cell, where an organic-inorganic perovskite compound acts as the light absorber. The scientists observed that charge carriers accumulate in a certain layer in these photovoltaic elements. If this jam can be dissolved, the...
