Abstract

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 photosencitizer 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 (I<2> / I<3><-> 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 portable electric devices and solar energy traffic lights as well as garden lamps, etc.

Description

technical field [0001] The invention relates to a manufacturing method of a prototype device of a nanocrystalline TiO2 solar cell, belonging to the fields of semiconductors and solar photovoltaics. Background technique [0002] In recent years, frequent conventional energy crises such as electricity, coal, and oil have made the energy problem increasingly prominent as a bottleneck restricting the country's economic development and residents' daily life. Developing new energy sources, getting rid of energy shortages, and seeking "new impetus" for economic development are important issues in my country's current energy development. Among all kinds of new energy, solar energy is an inexhaustible source of renewable energy, and it is also a clean energy that will not cause any environmental pollution or damage the ecological environment, so it has attracted much attention. [0003] Solar photovoltaic power generation is the most important form of solar energy utilization, and i...
