Abstract
The photo-semiconducting electrode of the present invention comprises a semiconducting substrate, a chemically adsorbed film formed thereon composed of at least one compound selected from the compounds represented by the formulas: formulas (I) R.sup.1 M.sup.1 Y.sub.1.sub.3, (II) R.sup.1 R.sup.2 M.sup.1 Y.sup.1.sub.2, (III) R.sup.1 R.sup.2 R.sup.3 M.sup.1 Y.sup.1 and (IV) R.sup.1 --SH, respectively, and a dye which is fixed to the surface of the chemically adsorbed film and has a functional group capable of reacting with a halogen atom. Because of this, the photo-semiconductor electrode of the present invention is capable of efficiently absorbing solar light and performing energy conversion and superior in photoelectric conversion efficiency, stability and durability. In addition, it can be easily produced.
