We recently published some work, led by PhD candidate David Macedo, presenting a method to get a more accurate measurement of return peak current in CV experiments. You can read the paper here:

We've also made a program that automatically performs this analysis, available at https://github.com/davedavedavem/diffusional-fitter
There's some sample data there too if you'd like to try it out.
The current version works for data with a single pair of peaks, but David Macedo is also working on future versions which can handle multi-peak CVs. He's looking at providing more options for capacitive current correction too.
The difficulty associated with accurately measuring the height of the back peak (Ipb) in cyclic voltammetry (CV) has long plagued electrochemists. Most commonly, Ipb is measured by extrapolating a linear fit from a selected region of a voltammogram after the switching potential (Eλ), but without su...
