Claim 0:
1. 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 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 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 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 deposited on the rear surface of the 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.
