A process for connecting photovoltaic cells in series, a photovoltaic cell connectable in series using the process, and a module obtained with the process

摘要

A process for series connection of two photovoltaic cells (1a, 1b) in series, comprising following stages: predisposing a first photovoltaic cell (1a) and a second photovoltaic cell (1b), both of a type comprising a photosensitive semiconductor layer (2) provided with front contacts (3a, 3b) and back contacts (4) arranged on opposite surfaces of the cell; partially superposing the two photovoltaic cells (1a, 1b), causing at least a partial superposing of the back contact (4) of the first photovoltaic cell (1a) on the front contact (3a, 3b) of the second photovoltaic cell (1b) and consequently establishing an electrical contact between the back contact (4) and the front contact (3a, 3b).
