Black silicon photodetector hits record-breaking 132% efficiency

Together, these advances made for a device with 130-percent external quantum efficiency. The team even had these results independently verified by the German National Metrology Institute, Physikalisch-Technische Bundesanstalt (PTB).

The researchers say that this record efficiency could improve the performance of basically any photodetector, including solar cells and other light sensors, and that the new detectors are already being manufactured for commercial use.

Eoin Treacy's view

The efficiency of solar cells has been improving steadily for the last forty years. The capital poured into the renewables sector following the collapse in interest rates a decade ago, has been the catalyst to greatly enhance the speed with which efficiency gains are being delivered.
