Claim 11:
12. A solar panel comprising:
a plurality of super cells, each super cell comprising a plurality of solar cells arranged in line with end portions of adjacent solar cells overlapping in a shingled manner and conductively bonded to each other to electrically connect the solar cells in series,
each solar cell comprising:
a n-type monocrystalline silicon base having a front surface, a rear surface, and sidewalls substantially perpendicular to the front surface, the sidewalls connecting the front and rear surfaces, at least one sidewall of the monocrystalline silicon base partially coated with a first transparent conductive oxide (TCO) which passivates the coated portion of the sidewall;
a first amorphous silicon layer comprising an intrinsic amorphous silicon layer and a n+ doped amorphous silicon layer, the first amorphous silicon layer having a front surface, a rear surface, and sidewalls connecting the front and rear surfaces, the rear surface of the first amorphous silicon layer in contact with the front surface of the n-type monocrystalline silicon base, at least one sidewall of the first amorphous silicon layer coated with the first TCO which passivates the coated sidewall;
a front TCO layer comprising the first TCO, the front TCO layer deposited on the front surface of the first amorphous silicon layer;
a second amorphous silicon layer comprises an intrinsic amorphous silicon layer and a p+ doped amorphous silicon layer, the second amorphous silicon layer deposited on the rear surface of the n-type monocrystalline silicon base;
a rear TCO layer comprising a second TCO, the rear TCO layer deposited on the second amorphous silicon layer; and
conductive grid lines on the front and rear TCO layers.
