Zusammenfassung:Provided are a copper chalcogenide light absorber capable of absorbing and blocking ultraviolet and near infrared rays at the same time, a light absorbing film, and a manufacturing method thereof. The manufacturing method comprises the steps of: preparing a first source solution including sulfur (S) and selenium (Se); mixing the first source solution with a second source solution including copper (Cu) to form a cooper chalcogenide particle; and coating the copper chalcogenide particle with an oxide to form a copper chalcogenide composite. 구리 칼코지나이드 광 흡수체의 제조 방법이 제공된다. 상기 구리 칼코지나이드 광 흡수체의 제조 방법은, 황(S) 및 셀레늄(Se)을 포함하는 제1 소스 용액을 준비하는 단계, 상기 제1 소스 용액에 구리(Cu)를 포함하는 제2 소스 용액을 혼합하여 구리 칼코지나이드 입자(cooper chalcogenide particle)를 형성하는 단계, 및 상기 구리 칼코지나이드 입자를 산화물로 코팅하여, 구리 칼코지나이드 복합체를 형성하는 단계를 포함한다.
