    摘要： Disclosed is a method for enhancing a yield of an α,β-unsaturated carboxylic acid obtained by liquid-phase oxidation reaction of an olefin or an α,β-unsaturated aldehyde. In particular, there is provided a method for producing an α,β-unsaturated carboxylic acid, wherein the method includes the step of carrying out oxidation reaction of an olefin or an α,β-unsaturated aldehyde in a liquid phase to obtain a reaction mixture containing an α,β-unsaturated carboxylic acid and an α,β-unsaturated carboxylic acid anhydride and the step of bringing the α,β-unsaturated carboxylic acid anhydride into contact with an alcohol or water to obtain an α,β-unsaturated carboxylic acid resulting from decomposition of the α,β-unsaturated carboxylic acid anhydride.

    摘要： A solar cell including a first electrode, a second electrode arranged opposite to the first electrode, an electron transport layer arranged between the first electrode and the second electrode, a dye layer D which is in contact with the electron transport layer, a hole transport layer arranged between the electron transport layer and the second electrode and being in contact with the dye layer D, and a barrier layer, and these elements are provided on a substrate. The barrier layer prevents or suppresses short-circuit between the first electrode and the hole transport layer. The porosity of the barrier layer is made smaller than that of the electron transport layer. The barrier layer is formed into a film-like shape and arranged between the first electrode and the electron transport layer. The solar cell can accomplish excellent photoelectric conversion efficiency by the provision of such a barrier layer.
