Fig. 3: Photovoltaic performance of solar cells based on XY1b and MS5+XY1b.

a Incident photon-to-electron conversion efficiency (IPCE) of the dye-sensitized solar cells (DSCs) based on XY1b and the co-sensitization of MS5+XY1b. The solid lines show the corresponding integrated photocurrent calculated from the IPCE. b Current density–voltage curves of the DSCs with XY1b and the co-sensitization of MS5 + XY1b measured under AM1.5G, 100 mW cm−2 condition. c Histogram of power conversion efficiency (PCE) of the DSCs based on co-sensitization of MS5+XY1b (16 samples). d Evolution of PCE of the DSCs based on MS5+XY1b measured under AM1.5G sunlight (100 mW cm−2) during continuous light soaking at 45 °C for 1000 h.
