About 50 years later, Charles Fritts constructed the first true solar cells using junctions formed by coating the semiconductor selenium with an ultrathin, nearly transparent layer of gold. Fritts’s devices were very inefficient converters of energy; they transformed less than 1 percent of absorbed light energy into electrical energy.…
