The Borexino experiment has been running since May 2007 at the Gran Sasso underground laboratory, in Italy. Solar neutrinos are detected with a large unsegmented liquid scintillator detector with unprecedented radioactive purity. The main results obtained include the measurement of the 7Be solar neutrino flux, the measurement of the 8B neutrino flux with electron recoil energy threshold of 3.0 MeV and the first clear detection of geo-neutrinos (see Aldo Ianni's talk in these proceedings for further details). Borexino has recently completed a large calibration campaign, and better results on 7Be solar neutrino measurement are expected soon. Short and medium term perspectives are summarized in the conclusions.
