I think it’s still research stage and it’s debatable whether to call this ‘solar’, but https://www.ucdavis.edu/curiosity/news/anti-solar-cells-photovoltaic-cell-works-night https://www.ucdavis.edu/curiosity/news/anti-solar-cells-phot...: “a specially designed photovoltaic cell could generate up to 50 watts of power per square meter under ideal conditions at night, about a quarter of what a conventional solar panel can generate in daytime” The idea is to capture the energy that escapes into space when solar panels cool down during the night.
