Abstract
A method of operating a multi-junction photovoltaic cell with junctions connected in series includes operating each junction at a different, respective maximum power point. A photovoltaic circuit includes: at least one multi-junction photovoltaic cell, comprising at least first, second, and third terminals; a first junction of the photovoltaic cell positioned intermediate the first and second terminals; a second junction of the photovoltaic cell positioned intermediate the second and third terminals; and a device for independently setting current flow through the first junction and the second junction to allow for maximum power point operation of each junction, the device for setting current flow being connected to the second terminal.
