nanoGe International Conference on Hybrid and Organic Photovoltaics (HOPV) started in Benidorm on year 2009. On ocasion of the 10th edition anniversary in the same setting, here I present a short account of the transformation of the scientific field, the evolution of dye-sensitised, quantum dots, and organic solar cells, and the hurrican of the perovskite soalr cells. There has been a significant change of scientific tendencies over the last years, mainly the explosion of digital communications and networking and fast publication. We comment how the conference itself reflected such tendencies.

In the second part of the talk I give a brief account of central characteristics of the solar cell device physics of the hybrid perovskite solar cells. A more complete picture of the device operation is emerging after including ionic effects in combination with electronic and optoelectronic properties. Charge accumulation at interfaces becomes manifest in terms of huge capacitance, but smart contact engineering allows one to control the surface capacitance and consequently reduce hysteresis and recombination.
