Which device captures light energy from the Sun and converts it into electrical energy?

• A. Turbine
• B. Solar panel
• C. Battery
• D. Windmill

Answer: (B)

The solar panel is the device specifically designed to capture light energy from the Sun and convert it into electrical energy through a process known as the photovoltaic effect. This process involves semiconductor materials, typically silicon, which generate electrical current when exposed to sunlight. When photons from the sunlight strike the semiconductor, they excite electrons, creating a flow of electricity. This ability is central to renewable energy strategies aimed at harnessing solar power to reduce reliance on fossil fuels and minimize environmental impact.

In contrast, turbines are mechanical devices that convert kinetic energy from wind or flowing water into mechanical energy, which can then be turned into electricity, but they do not directly capture solar energy. Batteries, while essential for storing electrical energy generated from various sources, do not capture energy themselves; they store it for later use. Windmills, similar to turbines, utilize wind energy rather than solar energy to generate power.
