                            [Object] To provide a polymer excellent enough in photoelectric conversion efficiency and in light resistance to be suitable for solar cells, also to provide a solar cell using the polymer, and further to provide an electronic product comprising the cell.
[Means] Embodiments of the present disclosure provide a polymer comprising a repeating unit of the following formula (M1).
(In the formula, R
1
is a substituent group selected from the group consisting of alkyl groups, and alkoxy groups; each R
2
is independently a substituent group selected from the group consisting of hydrogen, halogen, alkyl groups, alkoxy groups, and aryl groups; and each X is independently an atom selected from the group consisting of O, S and Se. The embodiments also provide a solar cell having an active layer containing the above polymer and further an electronic product comprising that cell.
