A new record efficiency (11.4%) of dye-sensitized solar cell was obtained by design and syntheses of donor–acceptor type co-adsorbents which effectively overcome the competitive light absorption by I−/I3−, avoid dye aggregation, and reduce the charge recombination. This result was certified by a public resea
Perovskite/Silicon tandem solar cells are also fabricated that achieve an efficiency of 30.72% (certified 30.09% @1.087 cm 2), which is the highest efficiency reported to date with a tunneling oxide passivating contact (TOPCon) c-Si substrate.
