ABSTRACT This study was conducted to determine the best weight ratio in producing graphene- cuprous oxide conductive film using nebulized spray pyrolysis method to deposit the material onto the substrate. The general objective of the study was to synthesize a conductive film with different weight concentration ratios of graphene oxide (GO) to copper acetate (Cu(Ac) 2 ) via spray pyrolysis. To be specific, the study aimed to identify the best concentration ratio for GO: Cu(Ac) 2 in terms of the resistance and absorbance of the deposited film and deposit the G-Cu 2 O solution using a modified automated nebulizer spray pyrolysis. The ratios are 3:5 or 60mg:100mg, 5:3 or 100mg:60mg, and 1:1 or 80mg:80mg respectively. There will be two trials for each weight ratio, and three replicates for each trial, resulting to a total of 18 samples. The resulting graphene-cuprous oxide solution will be deposited by an automated nebulizer system on glass substrates cut out from microscope slides while being heated at 200 degrees Celsius. The fabricated films were subjected to resistivity test. One-way ANOVA was used to determine the correlation of the different weight ratios with the resistance of the samples were tested. The graphite oxide-copper acetate weight ratio which produced the best characteristics in terms of conductivity are the 3: 5 and 1:1 weight ratios. The fabricated conductive films via spray pyrolysis could be applied to solar cells, capacitors, anode and cathode materials, other semiconductors, or a new material from graphene and metal oxide composites. However, the application of the deposited thin film as
a transparent conducting oxide for solar panels is less feasible since solar cells rely on transparency to maximize optical transmittance.
