Photo-induced absorption spectroscopy (PIA) setup

Product description:

This stand-alone piece of equipment is ideal for initial tests of new dyes for DSSC. A PIA spectrum of a dye-sensitized TiO₂ film quickly shows whether photoinduced electron injection is taking place. Subsequent addition of a redox electrolyte shows if the oxidized dye is being regenerated.

Analytical techniques included:

• Photo-induced absorption spectrum
• Frequency-dependent PIA response at a single probe wavelength

Information that can be obtained:

• Assessment of injection efficiency in DSSC
• Assessment of electron - dye recombination in DSSC
• Assessment of regeneration efficiency in DSSC
