What is it about?
The slow process in which the light absorbing dye molecules are adsorbed from solution on the nanocrystalline TiO2 photoelectrode film has been a handicap to the fast and cost-effective fabrication of dye-sensitized solar cells (DSSCs) using printing techniques. Here, we report a versatile dye sensitization process, achieved by inkjet printing a concentrated dye solution over the TiO2 film, which produces solar cells with equal performance and stability as obtained using the popular dye drop casting method

Why is it important?
The inkjet-dyed DSSCs exhibited high stability, retaining almost 100% of their conversion efficiency (η = 6.4 ± 0.2%) and short circuit current density (JSC = 14.2 ± 0.6 mA cm−2) when subjected to a 1000 h accelerated aging test under 1 Sun illumination at 35 °C, followed by additional 1154 hours under 0.5 Sun at 60 °C
Perspectives
This paper may pave the way for fully printed dye solar cells and open opportunities for entirely new cell designs.
