About two decades ago I came up with an idea to fix that problem.
Basically you build the PV panel on a Solar Hot Water panel, the water cools the PV cells and you get Hot Water. Win-win.
The PV panels might not get hot enough so it's probably more suited as a pre-heater for a smaller separate SHW panel operating as a booster.
I never really gave it much thought since, but a quick search reveals others have thought of it too:
