The method used to assemble dye‐sensitized photoelectrochemical (DS‐PEC) devices plays a vital role in determining its photoactivity and stability. We report a simple and effective method to assemble supramolecular DS‐PECs introducing PMMA as support material and a catalyst modified with long carbon chains as photoanodes. The long carbon chains in combination with PMMA allow to better immobilize the catalyst. DS‐PECs obtained by this simple method have display excellent photoactivities and stabilities. A photocurrent density of 1.1 mA cm −2 and a maximum IPCE of 9.5 % have been obtained with a 0.2 V vs NHE external bias.
