A new world record is made for converting sunlight into electricity in which researchers state that there is an increase in renewable energy.
Researchers of Longi – the world’s biggest solar panel manufacturer claimed that they have achieved 34.6 percent of power conversion with the help of their efficient tandem perovskite-silicon solar cell which broke their record of 0.7 percent. This record is more than 7 percent efficient as compared to standard silicon solar cells, which are used in almost all commercial solar panels. This means that using this design solar power will be more affordable and effective.
This new design made by perovskite is truly considered a “miracle material” for its potential application in batteries to telecommunication and improving renewable energy. Silicon solar panels have almost reached their maximum limits, researchers are now moving towards perovskite-based tandem cells to get more solar energy.
Perovskite-silicon solar cells are more efficient than traditional silicon cells. Their efficiency limit is about 43 percent compared to traditional silicon cells, they have a limit of just 29 percent.
They have been breaking solar efficiency records for the past three years and now it has been over 16 times that China’s Longi has broken this latest record.
This record was announced at the 17th International Solar Photovoltaic and Smart Energy Conference (SNEC) in Shanghai, China with an agreement to change global energy by giving a partnership with Saudi energy firm ACWA Power. The company said that they have achieved the new record by “optimizing the thin film deposition process of the electron transport layer, developing and using high-efficiency defect passivation materials, and designing high-quality interfacial passivation structures.”
Longi has not given any further details. Though the company will commercialize the technology soon. Meanwhile, Oxford PV in the UK can be one of the first customers of this new perovskite-based solar cells which can be established in production facilities in Germany.
