Abstract
The most important material for solar cells has been, and still is, silicon. In the year 2018, around 100 GW of new photovoltaic modules installed worldwide employed crystalline silicon (Si) as the absorber material. If we consider its peculiar properties and unique advantages with respect to the other materials for solar cell - availability, efficiency, low cost, no toxicity, long lifetime and sustainability - it should be the leading material also in the future. In this paper, the past, present and future of crystalline silicon solar cells will be discussed also through a personal lense: that of my research activity on silicon for PV carried out for several European Projects since 1991.
