Effect of coadsorbent on the photovoltaic performance of squaraine sensitized nanocrystalline solar cells

Michael Graetzel, Mohammad Khaja Nazeeruddin, Robin Humphry-Baker, Thomas Geiger, Jun Ho Yum, Soo-Jin Moon

The effect of chenodeoxycholic acid as the coadsorbent with a squaraine sensitizer on TiO2 nanocrystalline solar cells was investigated, and it was found that the coadsorbent prevents the squaraine sensitizer from aggregating on the TiO2 nanoparticles but ...
