There's one combining a heat exchanger and photovoltaics: https://triplesolar.eu/en/introduction/ https://triplesolar.eu/en/introduction/ > The front side of the PVT heat pump panel is similar to a solar panel and has solar cells to generate electricity. The backside is a heat exchanger that supplies the energy source for the heat pump. The heat exchanger-collector collects energy form the ambient temperature and additionally from daylight and sunlight. Not sure how it does throughout the whole season.
