The Inside Back cover illustrates the coalescence of binary chalcogenide nanoparticles to photoactive ternary nanocrystals. When oppositely charged nanocrystals are mixed in room temperature, they coalesce to the final product by simple stirring. The coalescence of polycation‐coated CuS nanoparticles and negatively charged In 2 S 3 nanoplates to CuIn 5 S 8 nanocrystals are driven by close contact of the particles due to electrostatic interactions. A photovoltaic device utilizing coalesced particles yields a power conversion efficiency of 1.9 %.
