<P>PROBLEM TO BE SOLVED: To provide a semiconductor electrode layer composed of a metal oxide semiconductor porous layer, which can be manufactured by low temperature calcination and which has all of the performance as an electrode, the hardness and the adhesion to a support member and achieves a higher photoelectric conversion performance when it is used to form a dye-sensitized-type solar cell, and to provide a method of manufacturing the semiconductor electrode layer, and an electrochemical device having the semiconductor electrode layer. <P>SOLUTION: The method of manufacturing a semiconductor electrode layer includes: preparing a coating liquid by adding, to metal oxide semiconductor fine particles 2, a first compound yielding titanium oxide on hydrolysis, and a second compound consisting of a niobium (V) compound yielding oxide or hydroxide on hydrolysis, or phosphoric acid or phosphoric ester; and putting a layer of the coating liquid on a support member 5 followed by low temperature calcination. The semiconductor electrode layer 1 formed by the method has a first oxide layer 3 made of titanium oxide and binding between the metal oxide semiconductor fine particles 2 and between the fine particle 2 and support member 5, and is improved in its conductivity by niobium (V) oxide or a phosphorous (V) compound. <P>COPYRIGHT: (C)2012,JPO&INPIT |
