Problems solved by technology

[0004] However, semiconductor electrodes (i.e., photoelectrodes) conventionally used in dye-sensitized solar cells have the following problems due to external stimuli (ultraviolet rays, chemical, heat, shock): structural destruction of photosensitive substances (ultraviolet rays, heat); The connection between the photosensitive substance and the metal nano-oxide is disconnected (chemical); or due to the structural characteristics of the interconnection between metal oxides, cracks are easily generated when subjected to external force (shock)
In addition, conventional photoelectrodes have many problems such as delamination of the electrodes from the substrate.
