In article number 1501070, Edgardo Saucedo and co‐workers report a breakthrough in kesterite‐based technologies, demonstrating that high‐voltage and high‐efficiency devices can be easily achieved using an innovative approach based on the introduction of a superficial Ge nanolayer, leading to efficiencies exceeding 10%. To illustrate this, the image shows how materials management at nanoscale level can have a strong impact on the macroscopic properties of photovoltaic devices.
