Photovoltaic cells convert sunlight into electricity. A photovoltaic (PV) cell, commonly called a solar cell, is a nonmechanical device that converts sunlight directly into electricity.Some PV cells can convert artificial light into electricity.

Incorporating magnetic nanoparticles in organic solar cells enhances stability and longevity, crucial for commercial viability. Optimal concentration and size of magnetic nanoparticles must be determined to maximize photovoltaic performance.
The bulk photovoltaic effect (BPVE) is a second-order optical process in noncentrosymmetric materials that converts the light into DC currents. BPVE is classified into shift current and injection current according to the generation mechanisms and their dependence on the polarization of light is sensitive to the spatial and time-reversal symmetry of materials. In

Recently, we developed a solar control of magnetism, allowing the magnetic moment to be manipulated by sunlight instead of the magnetic field, current, or laser. Here, binary and ternary photoactive systems with different photon-to-electron conversions are proposed.
An appropriate magnetic field (MF) can amplify the spin–orbit coupling effect between FA ions and chiral molecules, significantly increasing the magnetic dipole moment
Magnetic fields applied to solar cells, can influence different aspects of the photovoltaic process that include, magnetic field-assisted charge separation, magnetic nanostructures for light trapping, and magnetic field-induced quantum effects, among others.
"Today''s solar cells work by absorbing photons which are then sucked away to the electrodes to do the work," Prof. Schmidt says. "But as part of this process, a lot of this light is lost as heat. Which is why solar panels don''t run at full efficiency." Almost all photovoltaic solar panels on the market today are made from silicon. Co-author

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.

Solar energy is a form of energy which is used in power cookers, water heaters etc. The primary disadvantage of solar power is that it cannot be produced in the absence of sunlight.
