Abstract:
1. A photovoltaic string comprising: a plurality of serially connected solar cells; a positive lead and a negative lead on opposite ends of the photovoltaic string, one end of the plurality of serially connected solar cells being connected to the positive lead and an opposite end of the plurality of serially connected solar cells being connected to the negative lead; an open circuit voltage limiter across a group of solar cells in the plurality of serially connected solar cells, the open circuit voltage limiter having a positive terminal connected to the negative lead and a negative terminal connected to a connection between adjacent solar cells in the plurality of solar cells, the open circuit voltage limiter having a limiter voltage less than an open circuit voltage of the group of solar cells for current flowing through the open circuit voltage limiter in one direction and allows current flow through the open circuit voltage limiter in another direction; and a bypass diode having a cathode connected to the positive lead and an anode connected to the negative lead.
