A method of making a thin film photovoltaic cell having a pair (11, 12; or 31,32) of semiconductors located between a transparent electrical contact (10 or 34B) and an opaque electrical contact (14 or 35); and such a cell (1,1A,1B or 1C) itself. In order to avoid electrical path failures, at least one blocking layer (16,17,19,20,36 or37) is disposed in the cell in such a way that undesired electrical contact is prevented between the transparent and opaque electrical contacts, as well as between one of the electrical contacts and the semiconductor which is remote from it. |
