This research investigates the potential of reactive sputtering grown MoS₂ as a light absorber of solar cells. Ag/MoS₂/Ag structure is fabricated with a laterally oriented 10 nm thick MoS₂ film deposited on sapphire. Its electrical conductivity is characterized under dark and AM1.5 G illumination for comparison. Resistance is reduced under illumination due to the photocurrent generation from MoS₂. Calculation based on transfer matrix method shows about two times higher absorption in 10 nm thick MoS₂ with Ag back mirror. Enhanced absorption due to the reflection from the Ag back contact may account for the reduced resistance under illumination.
