Using a rotating cylindrical GZO target, low sheet resistance (similar to 11.67 Omega/square) and highly transparent (90%) GZO films were deposited with high usage (similar to 80%) of the cylindrical GZO target. High usage of the cylindrical GZO target in the CRMS system indicates that CRMS is a promising deposition technique to prepare cost-efficient GZO electrodes for low cost OSCs. Resistivity and optical transmittance of the CRMS-grown GZO film were mainly affected by substrate temperature because the grain size and activation of the Ga dopant were critically dependent on the substrate temperature. In addition, the performance of OSC fabricated on GZO electrode sputtered at 230 degrees C (11.67 Omega/square) is better than OSC fabricated on as-deposited GZO electrode (29.20 Omega/square). OSCs fabricated on the GZO electrode sputtered at 230 degrees C showed an open circuit voltage of 0.558 V. short circuit current of 8.987 m A/cm(2), fill factor of 0.628 and power conversion efficiency of 3.149%.
