PV cells convert sunlight directly into electrical energy through the photovoltaic effect.
Absorption Spectrum: PV cells are designed to match the solar spectrum's energy distribution to maximize absorption.
Temperature: Excessive heat can reduce efficiency due to increased resistance and altered semiconductor properties.

Photovoltaic cells convert sunlight into electricity through the photovoltaic effect. Efficiency is impacted by things like semiconductor material, design, sunlight intensity, and temperature. Efficiency is measured as the ratio of electrical power output to incident sunlight power, indicating the cell's effectiveness in converting sunlight into electricity.
