PV Power Generation Has Made The Latest Technological Breakthrough
A team at King Abdullah University of Science and Technology (KAUST) in Saudi Arabia has just set a new efficiency record for connected solar cells. Using so-called tandem solar cells, which combine two different materials, the team was able to achieve a groundbreaking level of efficiency.
The tandem solar cells were made by stacking two thin-film solar cells on top of each other. The top cell was made of a metal-halide perovskite material, while the bottom cell was made of a silicon material. The two cells were connected by a transparent conductive adhesive. This allowed the cells to work together to better capture sunlight and generate electricity.
The KAUST team was able to achieve an efficiency level of 33.2%, surpassing the previous record of 32.5% for this specific type of solar cell. This breakthrough paves the way for more efficient and cost-effective solar energy production.
"This record-breaking efficiency level demonstrates the potential of tandem solar cells, especially for high-efficiency solar modules," said Dr. Stefaan De Wolf, Associate Professor of Photovoltaics at KAUST.
Tandem solar cells have been gaining in popularity in recent years due to their ability to capture more of the sunlight spectrum. This results in higher efficiencies and lower costs per watt of electricity generated. With this new breakthrough, the KAUST team is helping to make solar energy even more competitive with traditional energy sources.
