Abstract Synopsis

  • The study explores how coating silicon photoanodes with amorphous titanium dioxide (TiO₂) using atomic layer deposition (ALD) can significantly extend their lifetime for solar fuel production.
  • It finds that residual chlorine (Cl) ligands in the TiO₂ film are harmful to the photoanode's durability and that post-ALD water treatment can reduce Cl content, improving the film’s stoichiometry and stability.
  • As a result of these improvements, the coated silicon photoanodes achieve a lifetime of up to 600 hours at high photocurrent densities, marking progress toward sustainable hydrogen generation.]
