Semitransparent Solar Cell Module (IMAGE) Linköping University Caption In a semi-transparent solar cell module as shown in the photograph, electrodes with two variants of the polymer PEDOT:PSS (commonly used in organic electronics) are used, where one acts as the anode and the other is modified to become the cathode. What appear as stripes across the solar cell module are lines of either cathode-type or anode-type material. The active layer that absorbs light and produces electrons is located between these electrodes. The individual solar cells are connected in series in the module.
