Restructuring the best way perovskite photo voltaic cells are designed can increase their effectivity and improve their deployment in buildings and past, in keeping with researchers with the Nationwide Renewable Power Laboratory (NREL).
Perovskite photovoltaic (PV) cells are manufactured from layers of supplies sandwiched collectively, with the highest and backside layers key to changing daylight to electrical energy. The brand new structure for the cells will increase the realm uncovered to the solar by placing the metallic contact layers side-by-side on the again of the cell.
“Taking the supplies on prime away means you’re going to have the next theoretical effectivity as a result of your perovskite is absorbing extra of the solar,” mentioned Lance Wheeler, a NREL scientist and lead creator of a brand new paper, “Complementary interface formation towards high-efficiency all-back-contact perovskite photo voltaic cells.”
Eradicating metallic layers from the entrance floor additionally permits photo voltaic panels to be seamlessly built-in into constructing facades. The design improves aesthetics of the cell and permits manufacturing on quite a lot of substrates that span glass to sheet metals. The
