abstract = {Coupling photovoltaics to electrochemical devices is one of
the major routes to overcome intermittent power generation
and facilitate further PV deployment. However, for practical
tests researchers are often at the whims of the
environmental conditions at their testing sites.
Experimental devices may be constrained to laboratory
environments, which makes coupling to physical photovoltaics
impractical. To avoid these limitations, photovoltaic
devices can be emulated using highly specialized custom
hardware. Adding to this development, we show emulation in
software using only common functions available in many off
the shelf laboratory power supplies. This approach offers
maximum flexibility in choosing a photovoltaic model and
operating conditions, both of which may be measured,
predicted or entirely artificial. It is geared towards
electrochemistry updating the output 2 times per second
typically and reproducing the current–voltage
characteristics of the photovoltaic device with high
accuracy (0.3 $\%$ error). It also provides fast convergence
for electrochemical loads and protects them from excessive
ripple currents.},
