To increase the performance of solar panels, an international collaboration—including researchers from KAUST and University of Toronto Engineering—has created a two-sided, tandem solar cell, built by bringing together the best of the perovskite and silicon technologies.

Out in the field, light primarily comes directly from the sun. Conventional tandem solar cells can already convert this light into electricity more efficiently compared to traditional silicon-only solar cells by absorbing additional wavelengths of light. […]
