Solar cells convert three-quarters of the energy contained in the Sun's spectrum into electricity -- yet the infrared spectrum is entirely lost in standard solar cells. In contrast, black silicon solar cells are specifically designed to absorb this part of the Sun's spectrum -- and researchers have recently succeeded in doubling their overall efficiency.kt8X-uSngd4
