Match-heads boost photovoltaic efficiency

Crystal growth on a nano/microscale level produces “match-head”-like, three-dimensional structures that enhance light absorption and photovoltaic efficiency. This is the first large structure grown on a nanowire tip and it creates a completely new architecture for harnessing energy.
