Hybrid Perovskites

Slow ‘Hot Electrons’ Could Improve Solar Cell Efficiency

Photons with energy higher than the ‘band gap’ of the semiconductor absorbing them give rise to what are known as hot electrons. The extra energy in respect to the band gap is lost very fast, as it is converted into heat so it does not contribute to the voltage. University of Groningen Professor of Photophysics […]

Improving Solar Cells by Watching Atoms Move in Hybrid Perovskite Crystals

Hybrid perovskites are promising materials for making next-generation solar cells because they are inexpensive to manufacture and are considerably efficient at converting light to electricity. A team of researchers led by the University of California San Diego has for the first time observed nanoscale changes deep inside hybrid perovskite crystals that could offer new insights […]

Scientists are Developing 2-D Layered Hybrid Perovskites for Optoelectronic Performance

At the edges of the perovskite layers, the new research discovered “layer-edge-states,” which are key to both high efficiency of solar cells (>12 percent) and high fluorescence efficiency (a few tens of percent) for LEDs. Scientists at Los Alamos National Laboratory and their partners are developing innovative 2D layered hybrid perovskites that allow greater freedom […]
