    摘要： A multi-modal maximum power point tracking optimization solar photovoltaic system is provided. A maximum power point tracking optimizer is connected to and powered by at least one solar cell. The maximum power point tracking optimizer configured to operate: in a pass-through mode when said at least one solar cell voltage is greater than a pass-through threshold and greater than a ratio of the open-circuit voltage of said at least one solar cell, said pass-through mode flowing current through a pass-through circuit; in an optimizing mode when said at least one solar cell voltage is greater than an optimizing threshold and less than a ratio of the open-circuit voltage of said at least one solar cell, said optimizing mode modulating current flow using a DC-to-DC switching circuit to direct the voltage of said at least solar cell towards said ratio of the open-circuit voltage; in an active bypass mode when said at least one solar cell voltage is less than an active bypass threshold, said active bypass mode flowing current through an active bypass circuit.

    摘要： Disclosed herein is add-on electronic circuit structures and methods for providing protection against reverse-electrical-current failures and for enabling comprehensive electrical (current-voltage sweep) and electro-optical (electroluminescence or EL using reserve current flow) testing of solar photovoltaic cells and modules having at least one multi-modal maximum-power-point tracking (MPPT) power optimizer integrated circuit chip to increase electrical energy generation yield of the modules. Such multi-modal MPPT power optimizer chips are used for distributed solar electric power generation enhancement in solar photovoltaic cells, modules, and systems under realistic operating conditions with non-ideal manufacturing and environmental variations (e.g., variable and/or non-uniform sunlight or daylight, mismatched cells, etc.).
