The invention discloses a manufacture method for adopting cheap merbromin dye to prepare the prototype device of a nano-crystalline TiO2 solar energy battery which is characterized in that a porous photoelectrode is manufactured by using commercial TiO2 nanometer powder and adopting a chemical fraction and powder knifing technique; a photo sencitizer is manufactured by the merbromin dye; then the prototype device of the solar energy battery is manufactured. The prototype device of the battery comprises an optical anode (including a transparent conductive glass, wire mesh printing silver electrode, compact TiO2 film, nano porous TiO2 thick film and a photoactivated dye absorbed on TiO2), an electrolyte (I2/I3- electrolyte system), a counter electrode (a platinum catalyst layer, a screen printing silver electrode and a transparent conductive glass) and an electrode seal material, etc. The invention can be applied to the broad fields of scale solar energy photovoltaic utilization, power supply and charging for p
