Photovoltaic materials and devices make use of semiconductors (the most popular being silicon) to convert sunlight directly into electricity.
Concentrating Solar Power (CSP)
By integrating thermal storage into the plant design, a concentrated solar power (CSP) plant can generate energy day and night, with or without clear skies.
