A multilayered design strategy for high-efficiency thin crystalline silicon solar cells

Solar power has become indispensable in our global pursuit of clean energy and sustainability. Today, about 95% of solar cells are made using crystalline silicon (c-Si). Most commercial designs employ a c-Si photoactive layer with a thickness of around 160–170 μm. However, since silicon alone makes up nearly half the cost of each solar panel, experts believe that next-generation c-Si solar cells will be much thinner.
