Effect of Ga/Cu Ratio on Polycrystalline C u G a S e ๐Ÿ Thin Film Solar Cell

Table 1

Electrical properties of various CuGaSe2 thin films having different Ga/Cu ratio in the film. Electrical properties were determined by van der Pauw Hall measurement method at room temperature. CuGaSe2 films were grown directly over SLG and cut into 5 รƒโ€” 5 โ€‰mm2 of sizes, for the measurement.
