Under these circumstances, the magnetic effects develop strength equivalent to a strong electric effect. “This could lead to a new kind of solar cell without semiconductors and without absorption to produce charge separation,” Rand said. “In solar cells, the light goes into a material, gets absorbed and creates heat.
Previous studies of the effect that a magnetic field has in organic solar cells are based on long time (μ s) OPV dynamic models, with mostly negative magnetic field effects in photocurrent generation 11, 30.
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.
Along with the demand for efficiency of power conversion systems, magnetic component selection for photovoltaic solutions becomes more challenging for design engineers. This article features key principles of power conversion and magnetics solutions in solar energy applications.
“In solar cells, the light goes into a material, gets absorbed and creates heat. Here, we expect to have a very low heat load. Instead of the light being absorbed, energy is stored in the magnetic moment. Intense magnetization can be induced by intense light and then it is ultimately capable of providing a capacitive power source.”
Since the process to make these solar cells is eco-friendly and of low cost, they can be used widely to make electricity. Recent studies have shown that an externally applied magnetic field can accelerate the transport of charge carriers in solar cells. However, it is not always possible to incorporate an electromagnet into a solar cell device.
Solar cell
A solar cell, also known as a photovoltaic cell (PV cell), is an electronic device that converts the energy of light directly into electricity by means of the photovoltaic effect. [1] It is a form of photoelectric cell, a device whose electrical characteristics (such as current, voltage, or resistance) vary when it is exposed to light. Individual solar cell devices are often the electrical ...
