A new type of photovoltaic cell using lead iodide as the photosensitive element and aluminum and silver as electrodes was constructed and then tested for open circuit voltage, monochromatic quantum yield of short circuit current, and fill factor. A similar cell was also fabricated using the familiar merocyanine dye M-8 as the photosensitive element for use in a control experiment. Minimal open circuit voltages of not more than 26 mV were obtained for lead iodide while much larger photovoltaic parameters were obtained for M-8. The poor and impermanent performance of lead iodide relative to the organic control suggests that lead iodide is probably an inferior material for Schottky cells. At best it will have to be deposited under strikingly improved conditions not experimentally accessible in this research.
