Ascent Solar Technologies has achieved a breakthrough in power-to-weight ratio for its superlight solar module, delivering more than 1700 watts of power per kilogram, operating at AM0, technically known as the space environment. At this performance, Ascent’s superlight module would weigh 66% less than a comparable PV system using the highest-quality crystalline silicon and with far less design complexity. The elimination of two-thirds of the weight is a critical improvement for satellites, space...
