Black materials reflect the most light from the Sun.


Black materials absorb the most light from the Sun.

Answer 1

Black materials absorb the most light from the Sun.

Explanation: dark surfaces absorb more incoming light (photons) rather than reflecting or scattering it. Solar cells are made dark and use anti‑reflective coatings so more sunlight is absorbed and converted to electricity (or heat), increasing the panel's efficiency.
