摘要

Solar photovoltaic(PV)technology is expected to play a key role in global carbon neutrality.The global new installed solar PV capacity over the past 20 years has grown at a compound annual growth rate of approximately 40％,far outpacing other energy sources such as coal,oil,natural gas,and wind[1].The strong momentum of the PV industry comes from its rapidly decreased levelized cost of electricity due to technological improvement and large-scale application.The lowest bid price for large-scale PV plants around the world has been reduced to 1.04 cents/kWh in 2021[2],and both the US and Chinese governments have announced in 2021 that the PV power generation will become the biggest power source in 20-30 years with a proportion of approximately 40％of the total power generation.It is encouraging to see that much progress has been made every year in solar cells and this editorial highlights the certified power conversion effi-ciency(PCE)in 2021 of three mainstream(silicon,perovskite and organic)solar cells.
