I have found that running enough water over the front surface to keep the
surface always covered by a very thin film produced a significant increase
in power output due to cooling.
In situations where you had a moderate amount of water available this may be
It does show that cooling by some means really works.
(Tried on 50 Watt Glass/EVA/Silicon standard pane;.)
It's EE actually, but TECH is fine.
