Résumé

Borexino is a large-volume liquid scintillator detector installed in the underground halls of the Gran Sasso National Laboratory in Italy. The data taking started in May 2007, after several years of development of purification techniques and construction. The Borexino phase I ended after about 3 years of data taking. All Borexino results within its solar neutrino program and their physical implications have been reviewed: the first real time measurement of the 7Be solar neutrino interaction rate, obtained with a precision below 5% and the absence of its day-night asymetry with 1.4% precision; the first direct evidence of the pep neutrino signal and the strongest experimental constraint of the CNO solar neutrino flux to date; the measurement of the solar 8B neutrino rate with 3 MeV energy threshold. Borexino sets also the world best limits on hypothetical anti-neutrino fluxes from the Sun assuming undistorted 8B spectrum.
