TECHNOLOGY FOCUS - ELECTRONICS - Preferred Components: The photoelectric conversion layer has a bulk-hetero structure containing organic photoelectric conversion dye, fullerene or a fullerene derivative, and fullerene polymer; and the layer has a volume ratio of the fullerene polymer which is set to at least 10% by irradiating an electromagnetic wave or electron beam on the photoelectric conversion layer (where the electromagnetic wave or electron beam is a visible ray having a wavelength of 400-700 nm). The charge blocking layer is an electron blocking layer or a hole blocking layer.    TECHNOLOGY FOCUS - IMAGING AND COMMUNICATION - Preferred Device: The device further comprises a charge blocking layer between the first or second electrode, and the photoelectric conversion layer; an electron blocking layer between the first electrode and the photoelectric conversion layer; and a hole blocking layer between the second electrode and the photoelectric conversion layer.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Components: The organic photoelectric conversion dye is an arylidene compound (preferably arylidene compound of formula (I)).Z1=a 2C ring, a 5-membered ring, a 6-membered ring, or a condensed ring containing at least one of a 5-membered ring and a 6-membered ring;L1-L3=methine (optionally substituted);n= greater than or equal to 0;Ar1=a divalent group selected from arylene or heteroarylene (both optionally substituted);andAr2 and Ar3=aryl or heteroaryl (both optionally substituted).    TECHNOLOGY FOCUS - POLYMERS - Preferred Components: The fullerene polymer is contained in the photoelectric conversion layer in a volume ratio of 10-80%. SPECIFIC COMPOUNDS - 35 Compounds are disclosed as (I) e.g. 2-(4-(di-naphthalen-2-yl-amino)-benzylidene)-indan-1,3-dione (IA), 2-(6-(di-naphthalen-2-yl-amino)-naphthalen-2-ylmethylene)-cyclopenta(b)naphthalene-1,3-dione; 2-(4-diphenylamino-benzylidene)-4,5,6,7-tetrafluoro-indan-1,3-dione; 6-(1-(4-diphenylamino-phenyl)-meth-(E)-ylidene)-(1)pyrindine-5,7-dione; and 2-(4-diphenylamino-benzylidene)-cyclopenta(b)anthracene-1,3-dione.
