Spectral Response
The spectral response is conceptually similar to the quantum efficiency. The quantum efficiency gives the number of electrons output by the solar cell compared to the number of photons incident on the device, while the spectral response is the ratio of the current generated by the solar cell to the power incident on the solar cell. A spectral response curve is shown below.

How Is Solar Panel Efficiency Measured?
A PV cell, commonly called a solar cell, is an electronic device designed to harness the energy from photons of light and convert it into electrical energy. This conversion process is achieved through the photovoltaic effect, whereby the solar cell generates an electric current when exposed to light.
