What is the minimum power of a flash of light of wavelength

Reference no: EM13276135

A circuit employs a silicon solar cell to detect flashes of light lasting 0.25 s. The smallest current the circuit can detect reliably is 0.36 uA. Assuming that all photons reaching the solar cell give their energy to a charge carrier, what is the minimum power of a flash of light of wavelength 620nm that can be detected?
