NOVELTY - An optoelectric transducer has an electron carrying layer and a hole transport layer provided between a transparent electronic current collection electrode and a hole current collection electrode. The hole transport layer contains polymeric material.    USE - For solar cell (claimed) used as power supply for electronic apparatus such as mobile telephone, electronic notebook and electronic paper, and auxiliary power supply of rechargeable or dry cell type electric appliance, table top calculator, wrist watches.    ADVANTAGE - The photoelectric transfer characteristics of the optoelectric transducer is favorable. The optoelectric transducer of solid type and excellent long-term stability is manufactured economically with favorable productivity. The optoelectric transducer and the solar cell have high conversion efficiency as the load of the photosensitization compound is increased and capture rate of the light is improved.    DETAILED DESCRIPTION - An optoelectric transducer has an electron carrying layer (3) and a hole transport layer (4) provided between a transparent electronic current collection electrode (2a) and a hole current collection electrode (2b). The hole transport layer contains polymeric material of formula (1): -(Ar2-N-(Ar1)-Ar3-CH=CH-Ar4-CH=CH)-.    Ar1=(un)substituted aromatic hydrocarbon;    Ar2,Ar3=bivalent group chosen from (un)substituted monocyclic, (un)substituted non-fused polycyclic or fused polycyclic aromatic hydrocarbon;and    Ar4=bivalent group chosen from (un)substituted benzene, (un)substituted thiophene, biphenyl, anthracene or naphthalene.    INDEPENDENT CLAIMS are included for the following:    (1) manufacture of optoelectric transducer; and    (2) solar cell.    DESCRIPTION OF DRAWING(S) - The figure shows a schematic view of structure of the optoelectric transducer.
