Japanese scientists build 23.27%-efficient heterojunction solar cell with 56.2μm-thick wafer

The 4cm2 cell showed a remarkable open-circuit voltage of 754 mV. It was fabricated with a hydrogenated nanocrystalline silicon (nc-Si:H) layer, which is said to show lower parasitic absorption and higher external quantum efficiency.
