Modern solar energy uses materials that convert sunlight to electricity or heat. The first solar cell, credited to Charles Fritts in 1883, provided a 1-2% sun-to-energy conversion efficiency. After years of research on improved materials and designs (especially the last 30 years), the current silicon-based solar cells offer up to 22% efficiency, and more complex... Continue Reading →
