The invention discloses a grapheme super-conduction perovskite photovoltaic light absorption material. Grapheme and lead iodide are prepared into stable solutions with uniform dispersion respectively and the stable solutions are sprayed on an FTO surface separately for seal reaction. FTO glass with a grapheme thin film and a lead iodide thin film is obtained and is then immersed in methylamine solution. Hydrogen iodic acid is added dropwisely and then seal aeration reaction and distill reaction are allowed. A thin film material is obtained after a cooling process. Finally, the thin film material is subjected to seal reaction and the grapheme perovskite photovoltaic light absorption material is obtained. The grapheme super-conduction perovskite photovoltaic light absorption material prepared in the invention is good in thin film structure compactness and has a good absorbing effect in a condition with visible light. The preparation method provided by the invention is moderate in reaction conditions, high in temperature controllability and requires no protection gases and the like. The reaction way is simple and industrial production can be realized.
