Substituted polycyclic aromatic compound as hole transport material in solar cells based perovskite solid state

摘要

Polycyclic aromatic compound substituted as material hole transporting in solar cells based solid state perovskite. # The present invention provides cell solar comprising a semiconductor material forming a structure of increased surface, a layer of organic-inorganic perovskite and hole transport material (HTM), wherein said HTM comprises a substituted polycyclic aromatic compound consisting of three to nine (3-9) linearly fused benzene rings. The invention further provides a process for producing a solar cell. Surprisingly, selecting a particular solvent and / or a particular concentration of HTM solar cells with efficiencies are obtained power conversion (PCE) exceptional.
