The Borexino experiment, located in the Laboratori Nazionali del Gran Sasso inItaly and widely known for its rich Solar Neutrino physics program, has recently celebrated the10 years of data taking. Among the achievements of the Borexino experiment solar program are:a precision measurement of 7Be neutrino flux with uncertainty of 3%, limit on its day/nightasymmetry, first spectral measurement of pp-neutrinos, first evidence of monoenergetic pepneutrinos at 5 sigma, 8B neutrinos detection with the lowest visible energy threshold of 3 MeV,observation of season modulation of the 7Be solar neutrino rate at 3.8 sigma and the best currentlimit on CNO neutrino flux.Borexino is now in its high-purity Phase II data taking, thanks to intense purificationcampaigns of scintillator in 2010-11 that were very successful in further reducing the already lowbackgrounds. The advanced tecniques of data analysis were improved, allowing to maximize thesignal/noise ratio. The detector was thermally insulated in order to improve the fluid stability.As an outcome, quality of the data has significantly increased leading to new levels of sensitivityto all solar neutrino fluxes. This allows a more sensitive probe for CNO neutrinos relevant tothe solar metallicity problem.
