Breakthrough Perovskite-on-Silicon Tandem Solar Cells Achieve 25% Efficiency
Oxford PV, a spinout from Oxford University, has achieved a groundbreaking milestone by developing the world’s most efficient solar panel. The newly created solar cell boasts an impressive 25% efficiency in converting the sun’s energy into electricity, surpassing the industry average ranging between 15-20%.
Perovskite-on-Silicon Technology Revolutionizes Solar Efficiency
The key to this remarkable achievement lies in Oxford PV’s perovskite-on-silicon tandem solar cells. Utilizing perovskite, a calcium titanium oxide mineral, enhances light absorption compared to the conventional crystalline silicon used in most solar panels, potentially revolutionizing the solar energy industry.
Collaboration and Theoretical Efficiency
Developed in collaboration with the Fraunhofer Institute for Solar Energy Systems in Germany, these panels boast a theoretical efficiency of 43%. Although this peak efficiency is yet to be demonstrated in real-world conditions, the breakthrough signals a significant advancement in solar technology.
Oxford PV’s Vision for the Solar Revolution
Chris Case, Chief Technology Officer at Oxford PV, envisions a solar revolution on the horizon. The continuous advancements in solar cell efficiency, he believes, position the industry for transformative change. The company aims to enhance module efficiency, enabling increased electricity generation within the same surface area, catering to residential, commercial, and utility-scale applications.
Pivotal Year for Oxford PV
Established in 2010, Oxford PV has dedicated over a decade to refining perovskite-based solar technology at its R&D site in Oxford and a pilot facility near Berlin, Germany. With substantial funding of €116 million from venture capital and government sources, the company anticipates a pivotal year in 2024. Plans include scaling up production at its German facility to achieve high volumes of hybrid solar cell manufacturing.
While expressing concerns about the UK’s lack of government incentives, Oxford PV is set to demonstrate its competitive edge in the global solar market, potentially challenging Chinese dominance. While cost competitiveness may be a challenge, the superior performance of its perovskite tandem solar cells positions Oxford PV as a key player in advancing cleaner, faster, and more effective climate change mitigation technologies.
