Abstract:
To provide a semiconductor film capable of realizing further enhancement of photoelectric conversion efficiency.
The semiconductor film includes semiconductor nanoparticles and a compound represented by the following general formula (1), in which the compound represented by the general formula (1) is coordinated to the semiconductor nanoparticles.
(In the general formula (1), X represents —SH, —COOH, —NH2, —PO(OH)2, or —SO2(OH), A1 represents —S, —COO, —PO(OH)O, or —SO2(O), and n is an integer of 1 to 3. B1 represents Li, Na, or K.)
