1. A device comprising:
a string of solar cells comprising
at least a first and second substantially rectangular crystalline silicon solar cells arranged in a shingled manner, each solar cell comprising front and rear surfaces each having a metallization pattern;
a plurality of electrically conductive interconnects connecting the first and second solar cells electrically in series, each interconnect in contact with the rear surface metallization pattern of the first solar cell and in contact with the front surface metallization pattern of the second solar cell; and
a plurality of flexible joints each comprising a cured liquid polymeric adhesive, each flexible joint in contact with the rear surface of the first solar cell, with the front surface of the second solar cell, and with only one of the plurality of electrically conductive interconnects, the cured liquid polymeric adhesive being electrically insulating and having a Shore A hardness of less than 80.
