Solid electrolyte, photoelectric converter and process for producing the same

A photocell comprising:

• a semiconductor layer composed of semiconductor particles carrying a dye and an electrolyte layer, the layers being provided between a counter electrode and an electrode formed on a surface of a substrate;
• wherein the electrolyte layer has a redox couple, an electrolyte composition, and a matrix polymer;
• and
• wherein the matrix polymer is a polymer formed by polymerization of a first compound having at least three isocyanate groups and a second compound having at least two nucleophilic groups containing active hydrogen, wherein said polymerization is performed in accordance with a Michael addition reaction.
