Abstract
Provided are a dye sensitized metal oxide semiconductor electrode having a metal oxide semiconductor film that can adsorb a sufficient amount of dye due to a high specific surface area and exhibits high electrical conductivity due to tight contact of metal oxide particles, and a dye sensitized solar cell that exhibits high power generation efficiency by using this dye sensitized metal oxide semiconductor electrode. The dye sensitized metal oxide semiconductor electrode is produced by forming a metal oxide semiconductor film on a transparent conductive film formed on a substrate. A stock solution containing a metal oxide precursor is jetted onto the transparent conductive film by electrospinning. A nanofiber layer containing a metal oxide precursor is deposited on the transparent conductive film, and this deposited layer is fired.
