1.Current situation and challenges of solar photovoltaic Solar photovoltaic(PV)is the most promising direction with the fastest growth among solar power technologies.The PV installed capacity has enjoyed an annual growth rate of 60%since 2008,and by 2012,the global accumulative installed capacity exceeded 100 GW for the fi rst time[1].It is predicted by the International Energy Agency that PV will generate about 11%of the world’s electricity by 2050,reducing CO2 emission by approximately 2.3 billion tons annually[2].However,solar PV also faces significant challenges.Firstly,solar energy has low energy intensity and is susceptible to sunlight hours,radiation levels and
