Solid‐State Monolithic Dye‐Sensitized Solar Cell Exceeding 10% Efficiency Using a Copper‐Complex Hole Transport Material and a Carbon Counter‐Electrode

Dye-Sensitized Solar Cell Several low-power electronics and Internet of Things devices could be charged using indoor photovoltaics. In article number 2300574, Santos, Ivanou, and Mendes show that one of the most promising are the monolithic dye-sensitized solar cells, which combine low-cost and simple fabrication, good power conversion efficiencies under room light, and attractive aesthetics.
