A method of forming a compound film can be fabricated by using the cadmium sulphide (CdS) compound and cadmium zinc telluride (Cd1-xZnxTe) compounds with the ways of coating the pastes on the glass substrates and sintering the films in a suitable atmosphere. The structural properties of (CdS and Cd1-xZnxTe) compound powders were analyzed by X-ray diffraction (XRD) analysis. The electrical properties of the films were investigated by photoconductivity measurement.

In this work, cadmium sulphide (CdS) buffer layer of CuInSe2 (CIS) thin film solar cell is fabricated by separate-melting Chemical Bath Deposition (CBD) methods.

As a remedy for environmental pollution, a versatile synthetic approach has been developed to prepare polyvinyl alcohol (PVA)/nitrogen-doped carbon dots (CDs) composite film (PVA-CDs) for removal of toxic cadmium ions. The CDs were first synthesized using carboxymethylcellulose (CMC) of oil palms empty fruit bunch wastes with the addition of polyethyleneimine (PEI) and then the CDs were embedded with PVA. The PVA-CDs film possess synergistic functionalities through increasing the content of hydrogen bonds for chemisorption compared to the pure CDs. Optical analysis of PVA-CDs film was performe
