In a major technological breakthrough, researchers have harnessed the capabilities of a ‘miracle material’ known as perovskite to significantly enhance solar panel efficiency. According to two groundbreaking studies, perovskite can push the power conversion efficiency rate of photovoltaic (PV) solar cells beyond the 30% mark. This is a huge leap considering the theoretical limit for conventional silicon PV cells has long been 29%.
Discovered around 15 years ago, perovskite’s unique properties enable it to harvest energy from a wider range of the light spectrum. This capability could revolutionize not just the renewable energy sector, but other industries as well.
By layering perovskite on top of silicon to create a ‘tandem device’, researchers have managed to supercharge the efficiency of existing PV technologies. This advancement retains the industry-standard configuration and is expected to significantly lower the cost of electricity generated from solar power.
Currently, the efficiency record for this next-gen solar cell is an impressive 33.7%, a milestone achieved by engineers at the KAUST Solar Center. In China, a startup recently announced plans to commence production of these tandem solar cells. With the abundance of perovskite, the cost could be slashed to just a fraction of that of traditional solar cells.
While the technology holds immense promise, there are still challenges to be addressed. Achieving durability under real-world conditions and scaling the cells to the size of conventional solar panels are key tasks ahead. Despite these hurdles, this breakthrough in perovskite technology marks a significant stride towards the future of renewable energy.
