Photoelectric conversion element, solar cell and composition

Abstract

in the formula, R1, R2, and L are specific groups; and Hal represents a halogen atom.

What is claimed is: 
     
         1 . A composition comprising:
 a compound represented by Formula (1a); and   a halogenated metal,
   R 1   3 Si-L-NR 2   3 Hal  Formula (1a)
 
   in the formula, R 1  represents a hydrogen atom, an alkyl group, a cycloalkyl group, an alkenyl group, an alkynyl group, an alkoxy group, an aryl group, a heteroaryl group, or an aliphatic heterocyclic group, R 2  represents a hydrogen atom, an alkyl group, a cycloalkyl group, an alkenyl group, an alkynyl group, an aryl group, a heteroaryl group, or an aliphatic heterocyclic group, L represents a divalent linking group, and Hal represents a halogen atom.   
     
     
         2 . A photoelectric conversion element comprising:
 a first electrode having a photosensitive layer including a light absorber on a conductive support; and   a second electrode facing the first electrode,   wherein the photosensitive layer is formed from the composition according to  claim 1 .   
     
     
         3 . The composition according to  claim 1 ,
 wherein R 1  is an alkyl group, an aryl group, or a heteroaryl group.   
     
     
         4 . The composition according to  claim 1 ,
 wherein L is a divalent linking group selected from an alkylene group, a cycloalkylene group, an alkenylene group, an alkynylene group, an arylene group, a heteroarylene group, —O—, —S—, and —NR L — or a divalent linking group formed by combining two or more linking groups, and   R 1  represents a hydrogen atom or an alkyl group.   
     
     
         5 . The composition according to  claim 4 ,
 wherein L is an alkylene group, an arylene group, or a divalent linking group formed of a combination of an alkylene group and an arylene group.   
     
     
         6 . The composition according to  claim 1 ,
 wherein the compound represented by Formula (1a) has an alkylene group in L, and L and NR 2   3  are linked to each other through the alkylene group.
