There is.
The albedo of solar panel products varies with the coating and level of dirt.
There are waterless methods of cleaning solar panels.
TPV Thermo-Photovoltaic (TPV) cells generate some energy from infrared (heat). Regular PV cells waste the heat difference.
The Shockley-Quiesser limit is only conjectured to be applicable to single-junction cells.
