Energy Efficiency Engineering

Description

The deposition of pollutant particles found in solar module cells, in fact, affects the efficiency of radiant power and at the same time affects the generating power of solar converting energy. Optical light incidence rays, which are considered as energy losses, also make a fraction of losses (FL), which are in fact quite complex to find the particle size and form of numerical calculations taken as polydisperse samples.
