• Resumen

  • In the Nanostructured Solar Cells Group at UPO we like to experiment with solar cells. We always treat them with care and delicacy, as we always use a small perturbation to analyze their response. This small perturbation can be an optical blink, of different colours or electrical, at either at a pleasant room temperature or at freezing cold conditions, in either total darkness or under extreme light soaking. Normally, all cells behave well, although perovskites ones do not appear to stand well our treatments. In any case, they always provide us with tasty information, in the form of resistances and capacitances, or kinetic constants, of different sorts. In addition, we like to run simulations and devise models of reference, to better understand their complex behavior. We do not know if we do it well or badly, but we always do it with frequency and intensity.
