Abstract

A photoelectric conversion material is disclosed in the present invention and comprises at least a cone material. The cone material is composed of an isomer and comprises a plurality of grains. The sizes of the grains are arranged from smaller ones to larger ones along a direction. In the meantime, a method for fabricating the above photoelectric conversion material is also disclosed here. The method comprises the following steps. First, a precursor is provided. The precursor comprises at least a cone material and the cone material is a multilayer structured material, such as sodium titanate and potassium titanate, formed by stacking first materials and second materials. And then, the precursor is annealed to let the second materials leave from the cone material, and the cone material becomes the above photoelectric conversion material with a plurality of grains.
