A plausible concept for a first space Solar Power Satellite demonstration is presented. The designed satellite is similar in size to a direct broadcast communication satellite. It uses a 40 kW solar array to provide power to a 20 kW IR laser. Because

Zinc diffused P on N GaSb cells are typically used in TPV systems. However, there are three potential advantages for developing N on P GaSb cells. First, because the minority electron carrier diffusion length in the P type wafer is longer than the ho
