生じる。2. Description of the Related Art Conventionally, photoelectric conversion elements using silicon, which is an inorganic semiconductor, have been devised and put into practical use. In recent years, research has been conducted on photoelectric conversion elements using organic materials. Organic materials have the potential to contribute to lowering the cost of solar cells in terms of both material synthesis and processing. Furthermore, a relatively uniform and large film can be made by dispersing or dissolving it in an appropriate solvent and casting it. However, photoelectric conversion elements using such organic materials have low photoelectric conversion efficiency because the organic materials have low conductivity. As a method for manufacturing devices with high photoelectric conversion efficiency, a method has been devised to expand the response wavelength range by providing a π-conjugated polymer layer and an organic dye layer between two electrodes (for example, in Japanese Patent Application Laid-Open No. 60-28
Publication No. 278). However, in this method, a voltage is applied between the electrodes to form a conductive electrolytically polymerized film on the electrodes, and the manufacturing method is complicated. Furthermore, the structure of a thin film obtained by electrolytic polymerization is not necessarily dense, and when producing a photoelectric conversion element or the like, a thin film causes an electrical short circuit.

題点があった。[Problems to be Solved by the Invention] When producing photoelectric conversion elements, there is a problem in that electrical short circuits occur. Further, there was a problem that the response wavelength range of light was narrow and the photoelectric conversion efficiency was low. Furthermore, when attempting to expand the response wavelength range of light using a conjugated polymer layer, there was a problem in that it had to be manufactured using a complicated method such as electrolytic polymerization.

効率を向上させる方法である。[Means for Solving the Problems] The present inventors solved the above problems and created a photoelectric conversion element that does not cause electrical short circuits, has an expanded light response wavelength range, and does not require a complicated manufacturing method. As a result of intensive study on the law, we have arrived at the following invention. That is, the present invention is a photoelectric conversion element having a soluble conjugated polymer layer and an organic pigment layer or an organic dye layer between two electrodes. Specifically, a soluble conjugated polymer layer is created by coating on one electrode, and a layer made of organic pigment or organic dye is created on top of that to achieve photoelectric conversion that is less prone to electrical short circuits. The purpose is to easily manufacture the device. Another method is to expand the response wavelength range and improve photoelectric conversion efficiency by interposing a soluble conjugated polymer layer and an organic dye layer between electrodes.
