Title and Abstract of the Speech:
Passivating contacts for silicon and perovskite solar cells

In silicon and perovskite solar cells, carrier recombination at the electrical contacts is increasingly recognized as a key factor limiting device performance. In this presentation we discuss the different available strategies to passive contacts of both types of photovoltaic technologies. Implementing such contacts opens the road to solar cells working in their radiative limit.
