Efficient dye-sensitized solar cells (DSSCs) through atmospheric pressure plasma treatment of photoanode surface

Atmospheric pressure plasma (APP) source was used for surface activation of polyetherimide (PEI) polymer substrate for dye-sensitized solar cells (DSSCs) fabrication. Changes in the water contact angle (WCA) and FE-SEM analysis of PEI samples before and after plasma treatment were used to assess the...
