First, as already described in our previous post, there are
conversion efficiency requirements that the PV systems have to hit, depending on what PV technology is used.
Towards the goal, research in the Membranes and Mesoscale Assembly program is directed towards the engineering of membranes that satisfy the structural and chemical stability, gas / fuel permeability, and ionic - conductivity
requirements for solar - fuels devices as well as towards experimental and theoretical investigations of structured catalyst / light - absorber / membrane assemblies that maximize solar - energy
conversion efficiencies.
