Scientists have changed the structure of the solar battery and increased its efficiency by 125%

In a new study, a team of scientists from the UK, Portugal and Brazil found that changes in

The position of the grid pattern in the solar cell design can increase the current generated by crystalline silicon (c-Si) by 125%. This is the first time that minimal manipulation by researchers has resulted in a significant increase in the efficiency of the device.

Scientists explained that instead of introducing newstructural designs based on natural textures or computational algorithms, the researchers focused on theoretical calculations of what could optimize the scattering and diffraction pattern of sunlight.

Their modeling showed that the lattice lines,located in a simple periodic, quasi-random structure, optimize the operation of the "photonic region" of the solar battery: the region within the photonic structure, in which the main diffractive element is located in one-dimensional order.

In an experiment, the team modeledthe performance of the photonic region in the form of a patterned checkerboard made of a crystalline silicon plate with a thickness of only 1 micrometer (several times thinner than a web of silk), and compared it with other types of solar cell designs, including a flat element, vertical lattice lines, crossed lines and others.

The results showed that the chessboard withthe arbitrary arrangement of its repeating elements generates more current than any of the other elements. Battery efficiency is 125% higher than non-grid counterparts.
