NOVELTY - A solid-state hole transport composite material (ssHTM) comprises neutral charge first p-type organic semiconductor; chemically oxidized first p-type semiconductor, where the dopants are silver(I) containing materials; and a reduced form of the silver(I) containing material, retained as a functional component in the ssHTM.    USE - As solid-state hole transport composite material used in solid-state dye solar cell (claimed).    ADVANTAGE - The composite material shows effective in situ doping of hole-transport material (HTM) matrices for improved ssDSC performance. Optical measurements confirmed the successful and efficient one-electron oxidation of Spiro-OMeTAD. The prototype ssDSC devices demonstrate significant performance enhancements relative to control devices (without AgTFSI). Thus there is suppression of recombination events arising directly from an increase in HTM conductivity due to appropriate chemical (oxidative) doping.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following:    (1) synthesizing ssHTM involving in a single step, mixing a first p-type organic semiconductor with a silver(I) containing material; at least partially chemically oxidizing a portion of the first p-type organic semiconductor: as a result, creating a ssHTM comprising: a neutral charge first p-type organic semiconductor; a chemically oxidized first p-type organic semiconductor, and, a reduced form of the silver(I) containing material, retained as a functional component in the ssHTM;    (2) solid-state dye solar cell (ssDSC) with ssHTM, the ssDSC comprising: a transparent platform; a transparent conducting oxide (TCO) overlying the transparent platform; a sensitized n-type semiconductor overlying the TCO; the ssHTM overlying the dye-sensitized n-type semiconductor; and a metal layer overlying the ssHTM.    DESCRIPTION OF DRAWING(S) - The figure shows partial cross-sectional views of a solid-state dye solar cell (ssDSC) with a solid-state hole transport material (ssHTM).
