Abstract
A photovoltaic cell () including a first front collector layer (), an amorphous silicon layer () on the first layer () and a second conductive layer () on the amorphous silicon layer (). Electrical connection of the second conductive layer () to the first layer () is made through the amorphous silicon layer () at the periphery of the photovoltaic cell, the electrically conductive layer () comprising a positive peripheral bus ('), which is connected to the TCO first layer () and to at least one positive connection terminal at one end of the positive peripheral bus, and a negative peripheral bus, which is connected to a negative connection terminal, and the positive and negative peripheral buses being asymmetrical relative to one another, with the positive peripheral bus being longer than the negative peripheral bus.
