Abstract

An object of the present invention is to provide a compound that is useful as a hole transport material for providing a device for converting light into electricity that is capable of extracting current with high efficiency, and a device for converting light into electricity and a solar cell that include the compound in a hole transport layer and have favorable light/electricity conversion characteristics. The present invention provides a compound represented by the general formula (1) below. In the formula, Rto Reach represent a hydrogen atom, an alkoxy group having 1 to 20 carbon atoms, or the like, and Y represents an oxygen atom or CRR, where Rand Reach represent a nitrile group, an acyl group having 1 to 10 carbon atoms, or the like.
