Abstract

Organic-inorganic perovskites have been used as the light absorbing layer in solar cells since 2009 and have since seen a ground breaking rise in efficiency in a relatively short period of time. Today, perovskite based solar cells have reached efficiencies of over 24% making them a potential competito...
