The aim of this research was to study the electrical conductivity for electrical conductivity of chlorophyll with polythiophene (PT) thin film on indium tin oxide as P‐N heterojunction solar cell. The polythiophene thin film is deposited to the Indium Tin Oxide (ITO) substrate using electrochemistry method. The chlorophyll (CHLO) thin film then been coated on polythiophene thin film using spin coated method. Current and voltage of ITO/PT/CHLO thin film is measured in the dark and under different light intensity using four points probe. The result shows that combination of the thinnest polythiophene thin film with the thickest chlorophyll thin film produce the highest conductivity reach up to ±0.1 Sm−1 (raise 22% under illumination compared to the electrical conductivity in the dark condition).
