A rectangular solar cell has dimensions of 6 m 4m. On an average daylight the intensity of sunlight is about 100 mW/cm. Assume that the cell absorbs all of the incident sunlight and converts the electromagnetic energy into electric energy with a power conversion efficiency of 25%. The incident light is perpendicular to the surface of the solar cell. Take the speed of light as c = 3 108 m/s, the permittivity of the free space as o = 9 x 10- C/(N m). . 19. Find the average power of electricity generated by the solar cell. (a) 2 kW (b) 12 kW (c) 8 kW (d) 6 kW (e) 1 kW 20. What is the average force exerted on the solar cell, due to the incident light? (a) 12.0 10-5 N (b) 8.0 10-5 N (c) 2.0 10-5 N (d) 6.0 10-5 N (e) 12.0 10-4 N A rectangular solar cell has dimensions of 6 m 4m. On an average daylight the intensity of sunlight is about 100 mW/cm.
