A photosensitive layer composition for a photosensor according to an embodiment of the present invention includes a first photosensitive material including a compound represented by a chemical formula 1; and a light signal amplification/noise suppressor containing a bifullerene compound. In the chemical formula 1, n is a natural number. The optical signal amplification/noise suppressor can effectively separate charges formed by optical signals and suppress the flow of charges in a reverse direction. 본 발명의 실시예를 따르는 광센서용 광감응층 조성물은 하기 화학식 1로 표시되는 화합물을 포함하는 제 1 감광물질; 및 비풀러렌 화합물을 포함하는 광신호 증폭/노이즈 억제기;를 포함한다.
