Abstract: There are provided three-dimensional photovoltaic structures and a power optimizer for a photovoltaic power generation apparatus. The photovoltaic structure may include two or more photovoltaic material face sets including one or more photovoltaic material faces with at least in part in different orientations to each other. In embodiments, each photovoltaic material face may be operatively coupled to power optimizer, for example maximum power point tracking (MPPT) electronics, enabling independent power optimization of the power output of each face.
