Solar technology firm LONGi has set a new world record for silicon-perovskite tandem solar cells by reaching 33.9 percent efficiency. The achievement has been certified by the US National Renewable Energy Laboratory (NREL), a company press release has claimed.
Renewable energy research has seen a significant push with the world looking to reduce its dependence on fossil fuels. Scientists worldwide have been working to improve the efficiency of solar panels so that more energy can be generated from the same area where they are installed.
The standard single-junction solar cells found in all commercial installations have a theoretical limit of 33.7 percent, also referred to as the Shockley-Quieser (S-Q) limit. To overcome this, researchers have been working with different materials that can be paired with silicon to improve efficiency. Significant success has been achieved with perovskites.
