    Copper-doped cadmium telluride thin-film solar cells have high efficiency, but limited hole density and Cu diffusion allow little room for further improvements in device performance. Now, arsenic-doped cadmium telluride thin films show enhanced hole density and lower dopant diffusivity leading to 20.8%-efficient solar cells.

    The optimization of building envelopes plays a substantial role in reducing global energy consumption and meeting energy and climate targets. Now, a dynamic photovoltaic building envelope has been demonstrated to improve building energy self-sufficiency, while adapting to changing weather conditions and occupant needs.
