Figure 6: Photovoltaic performance characteristics of recycled PSCs.
From: Selective dissolution of halide perovskites as a step towards recycling solar cells
Normalized trends in the (a) short-circuit current density, (b) open-circuit voltage, (c) fill factor and (d) efficiency of MALI-based PSCs fabricated on 1st-, 2nd-, 3rd-, 4th-, 5th- and 10th-time recycled substrates compared with those of the MALI-PSC fabricated on the newly prepared substrate. (e) J–V curves for two-step processed MALI-based PSCs (red spheres) and (FALI)0.85(MALBr)0.15-based PSCs (blue squares) on new (dotted lines and empty symbols) and once-recycled (solid lines and filled symbols) mp-TiO2/TCG substrates. The error bars in a–d indicate the s.d.’s calculated from five samples.
