Simultaneously and Synergistically Harvest Energy from the Sun and Outer Space - ScienceDirect
If you can take out the backing metal foil of a PV panel, then line the bottom with a narrow band IR re-emitter that converts rooftop heat to a band that can escape out of the atmospheric IR window, allows roof cooling and power generation simultaneously in theory.

Solar air conditioning - Wikipedia
Solar air conditioning refers to any air conditioning (cooling) system that uses solar power.

This can be done through passive solar, solar thermal energy conversion and photovoltaic conversion (sunlight to electricity). The U.S. Energy Independence and Security Act of 2007[1] created 2008 through 2012 funding for a new solar air conditioning research and development program, which should develop and demonstrate multiple new technology innovations and mass production economies of scale. Solar air conditioning might play an increasing role in zero-energy and energy-plus buildings design.[who?]
