> Is there potential to optimize solar beyond the perceived limits? 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.
