Microconcentrator Solar Panel Architectures Achieving High Specific Power for Deep Space Missions
Microconcentrator photovoltaics (microCPV) are emerging as a promising solution for powering spacecraft in deep space, where conventional solar arrays are challenged by extremely low‐intensity, low‐temperature conditions. This work presents the design, development, and characterization of two optical architectures aiming at maximizing specific power (W/
