Disclosed herein is a material, and a solid electrolyte and a photovoltaic
device using the same. When the material is used as a hole transporting
layer material of the photovoltaic device, the reduction of an
electrolytic layer resulting from leakage or volatilization of an
electrolytic solution is prevented, thus the battery characteristics,
long-term stability, and reliability of the photovoltaic device are
improved.
