is developed, which exhibits a high solar power conversion efficiency
(PCE) of 12.76% with a current density of 27.61 mA/cm2.
The present work demonstrates the integration of an LG6 dye sensitizer
for near-infrared light utilization and an N719 dye sensitizer for
effective visible light capture in the bifacial tandem cell design.
The developed bifacial tandem cell with LG6 and N719 dyes exhibited
better incident photon-to-current conversion efficiency spectra. The
stability was tested for up to 814 h, and a stable performance was
detected. The developed mini-module exhibited a maximum point power
density output of 1.41 mW/cm2. This work opens up a pioneering
research approach for bifacial tandem solar cells with the DSSC.
