The solar cell has energy losses, so does not covert 100% of the solar power to electricity. Some of the light is reflected from the surface of the solar cell, and some of the light is blocked by the metal lines on top of the solar cell that conduct electricity through the cell.

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 …

Introduction. The function of a solar cell, as shown in Figure 1, is to convert radiated light from the sun into electricity. Another commonly used na me is photovoltaic (PV) derived from the Greek words "phos" and "volt" …
A solar module comprises six components, but arguably the most important one is the photovoltaic cell, which generates electricity.The conversion of sunlight, made up of particles called photons, into electrical energy by a solar cell is called the "photovoltaic effect" - hence why we refer to solar cells as "photovoltaic", or PV for short.
The "quantum efficiency" (Q.E.) is the ratio of the number of carriers collected by the solar cell to the number of photons of a given energy incident on the solar cell. ... Internal quantum efficiency. L p is the emitter diffusion length (µm), S p is the front surface recombination velocity (cm/s), L n is the base diffusion length (µm), S n is the rear …
