  We present a new computational approach to simulate linear sweep and cyclic
voltammetry experiments that does not require a discretized grid in space to
quantify diffusion. By using a Green's function solution coupled to a standard
implicit ordinary differential equation solver, we are able to simulate current
and redox species concentrations using only a small grid in time. As a result,
where benchmarking is possible, we find that the current method is faster (and
quantitatively identical) to established techniques. The present algorithm
should help open the door to studying adsorption effects in inner sphere
electrochemistry.
