There are several technologies that can be used to harness solar energy, including solar thermal, photovoltaic cells, and photosynthesis. Solar thermal technology uses mirrors or lenses to concentrate sunlight, which is then used to heat a fluid that drives a turbine to generate electricity. Photovoltaic cells, on the other hand, convert sunlight directly into
