Question

question: solar cells, also known as ____ cells, are usually made of semiconductor materials that absorb sunlight and store energy. answer options: select one of four photochromatic photogenic photovoltaic fuel

Explanation:

To solve this, we analyze each option:

• "photochromatic" relates to color change with light, not solar energy conversion.
• "photogenic" means producing light or being photogenic (attractive in photos), not related to solar cells.
• "photovoltaic" refers to the conversion of light (photons) into electricity (voltage), which is exactly what solar cells do (they are also called photovoltaic cells).
• "fuel" cells are different, using chemical reactions to produce energy, not light absorption like solar cells.

Answer:

C. photovoltaic (assuming the options are labeled A: photochromatic, B: photogenic, C: photovoltaic, D: fuel; since the original options don't have labels, but based on the content, the correct term is photovoltaic)
