  • Combine solvent, CdS, and TiO2 with mixing and light heat, ~40 C.Mix for at least 30 minutes before applying.It is also possible to make solar paint using a pseudo-SILAR (successive ionic layer absorption and reaction) process.

  • Apply solar paint to an optically transparent electrode.Apply paint using a paint brush or with a doctor-blade method.Anneal using a hot air gun.
  • Add drop of 1M/1M Na2S/S electrolyte to the Reduced Graphene Oxide/Cu2S counter electrodeSandwich the photoanode with the counter electrode and clip togetherTest the photoelectrochemical performance of the cell under AM 1.5, 100 mW/cm2 illumination.

    1. 1. Current preparation techniques for quantum dot solarcells require time-intensive, multi-step procedures. Inorder to make these cells commercially viable, thisprocess must be simplified.Here we present a first step towards creating aneconomically viable solar paint that can be applied bysimply painting onto an electrode.
