Initial infusion of organic dye into μ-FGPVs and resulting increase in photovoltaic performance.

(a) Images illustrating the progressive infusion of dye and electrolytes through the gel-vascular network at 5 and 15 min after injection of the solution. Scale bar = 1 cm (see Supplementary Fig. S3 for more snapshots of the solute distribution at different times). The injection rate is 10 μl/min. (b) I–V curves of the μ-FGPVs under illumination after the first injection of the aqueous solution of dye and electrolytes.
