Record efficiency for perovskite-based light-emitting diodes

Efficient near-infrared (NIR) light-emitting diodes of perovskite have been produced in a laboratory at Linköping University. The external quantum efficiency is 21.6 percent, which is a record. The results have been published ...

Making solar cells is like buttering bread

Formamidinium lead iodide is a very good material for photovoltaic cells, but getting the correct stable crystal structure is a challenge. The techniques developed so far have produced poor results. However, University of ...

Researchers discover new material to help power electronics

Electronics rule our world, but electrons rule our electronics. A research team at The Ohio State University has discovered a way to simplify how electronic devices use those electrons—using a material that can serve dual ...

2-D material has space vehicle applications

A new study from The Australian National University (ANU) has found a number of 2-D materials can not only withstand being sent into space, but potentially thrive in the harsh conditions.

Mixed-cation perovskite solar cells in space

With the continuous improvement of efficiency and stability, perovskite solar cells are gradually approaching practical applications. PSCs may show the special application in space where oxygen and moisture (two major stressors ...

When a defect might be beneficial

In the quest to design more efficient solar cells and light-emitting diodes (LEDs), a team of engineers has analyzed different types of defects in the semiconductor material that enables such devices to determine if and how ...
