By covering cubic silicon carbide in nanopores, researchers have created an efficient light-powered material for splitting water to produce hydrogen.

A new, inexpensive dipping process using a sulfolane additive can produce high-quality perovskite crystalline thin film for use in solar cells.

Researchers have found a material that can switch between a window and a mirror in a quadrillionth of a second when struck by a short laser pulse.

Researchers have discovered that the electronic properties of halide perovskites hinge on the way their atomic lattice twists and turns.

By combining photonic crystals with a polymer substrate, researchers have developed a photonic material that can move and fold when illuminated.

A novel glass display with a high white light contrast ratio can smoothly transition between a broad spectrum of colors when electrically charged.

Researchers used ultrafast nanometric imaging to show, for the first time, that populations of carbon dots contain both good and bad emitters.

Researchers have developed a new way to produce nonlinear optical processes, by stacking and twisting layers of 2D hexagonal boron nitride.

Scientists have discovered the crucial role played by one of the solvents used in the fabrication process for perovskite solar cells.
