Abstract

A high efficiency configuration for a solar cell module comprises solar cells arranged in a shingled manner to form super cells, which may be arranged to efficiently use the area of the solar module, reduce series resistance, and increase module efficiency. The solar cell module may comprise for example a series connected string of N greater than or equal to 25 rectangular or substantially rectangular solar cells having on average a breakdown voltage greater than about 10 volts, with the solar cells grouped into one or more super cells each of which comprises two or more of the solar cells arranged in line with long sides of adjacent solar cells overlapping and conductively bonded to each other, and with no single solar cell or group of <N solar cells in the string of solar cells individually electrically connected in parallel with a bypass diode.
