When light photons strike the surface of a solar cell, they transfer their energy to electrons in the cell’s semiconductor material (usually silicon). This energy boost allows the electrons to break free from their atoms and flow through the material, creating an electric current. 4. Semiconductor Materials:
The shorter the wavelength of incident light, the higher the frequency of the light and the more energy possessed by ejected electrons. In the same way, photovoltaic cells are sensitive to wavelength and respond better to sunlight in some parts of the spectrum than others.
Different studies presenting here to study the interaction of magnetic field with the charge states and its influence on the photovoltaic cells. One of the studies done by the Casado et al. for an organic cell where affect of magnetic field on the system lead to enhancement in the efficiency.
In most cases, the DC electricity is converted to alternating current (AC) electricity using an inverter, making it compatible with the electrical systems in homes and businesses. The science behind solar energy is a beautiful interplay of physics, chemistry, and engineering.
In addition, solar panels do not emit electromagnetic waves over distances that could interfere with radar signal transmissions, and any electrical facilities that do carry concentrated current are buried beneath the ground and away from any signal transmission.” - FAA Solar Guide.
Photovoltaic cells are sensitive to incident sunlight with a wavelength above the band gap wavelength of the semiconducting material used manufacture them. Most cells are made from silicon. The solar cell wavelength for silicon is 1,110 nanometers. That's in the near infrared part of the spectrum.

If photovoltaics are ever going to be part of our quest to get utilities away from burning fossil fuels to generate our electricity, we need to convert the DC current a solar cell produces to the more useful AC currents.
Electromagnetic waves bring energy into a system by virtue of their electric and magnetic fields. These fields can exert forces and move charges in the system and, thus, do work on them. However, there is energy in an electromagnetic wave itself, whether it is absorbed or not. Once created, the fields carry energy away from a source. If some energy is later absorbed, the field …
Any radiation with a longer wavelength, such as microwaves and radio waves, lacks the energy to produce electricity from a solar cell. Any photon with a energy greater than 1.11 eV can dislodge an electron from a silicon atom and send it into the conduction band.
