Hunt Energy announced reports that its solar technology company, Hunt Perovskite Technologies (HPT), has achieved an industry-leading milestone in the development of a highly-durable perovskite technology for the manufacture of low-cost printed solar cells.

In December 2019, HPT successfully demonstrated that its ink-based process was able to produce a perovskite solar cell that exceeded key benchmarks recognized by the solar cell manufacturing industry and exceeded the International Electrotechnical Commission (IEC) durability thresholds in temperature, humidity, white light and ultraviolet (UV) stress testing while reaching efficiency performance levels of 18%.

"The Hunt team is thrilled to have achieved this level of progress to-date," said Hunter Hunt, chief executive officer of Hunt Energy. "We strategically chose to develop perovskite solar several years ago; we envisioned its strategic importance as an innovative new energy technology in addressing the world's energy needs for the future, as well playing a part in combating climate change. As part of the global energy transition that is occurring, our solar team is hoping to make a meaningful contribution."

Interest in perovskite solar technology has increased significantly since debuting in 2009 given its potential for high efficiency, low cost, and applicability. However, while researchers worldwide have made rapid progress on improving perovskite solar cell efficiency, progress in improving durability has been slow.

Hunt's results show that its technology has achieved improved durability while achieving high efficiency, and it has done so using a scalable, potentially lower cost manufacturing process. To date, Hunt has been granted 18 patents by the United States Patent and Trademark Office and 30 additional patents by various foreign patent offices.

"When we started developing this technology, we took a different approach from others in the industry," said Michael D. Irwin, chief technology officer of Hunt Perovskite Technologies. "While we knew it would initially be a harder path to follow, we also believed it would be a better way to realize the overall application potential of an all perovskite solar cell, both in terms of cost and, more importantly, durability."

For the past six years, Hunt has been working as a corporate partner with researchers at the U.S. Department of Energy's National Renewable Energy Laboratory (NREL) on the development and testing of its perovskite technology.

"Hunt has been an important partner and collaborator in NREL research on perovskite solar cells from the early days of our investigation into these materials", said Joe Berry, senior scientist on NREL's Perovskite and Hybrid Solar Cells Team. "We look forward to continued collaboration with our industry partners as we seek to develop and, ultimately, deploy these promising technologies from the laboratory to the marketplace."

Oblique electrostatic inject-deposited TiO2 film leads efficient perovskite solar cells
Kanazawa, Japan (SPX) Feb 11, 2020
The need to efficiently harvest solar energy for a more sustainable future is increasingly becoming accepted across the globe. A new family of solar cells based on perovskites - materials with a particular crystal structure - is now competing with conventional silicon materials to satisfy the demand in this area. Perovskite solar cells (PSCs) are continually being optimized to fulfill their commercial potential, and a team led by researchers from Kanazawa University has now reported a new and simp ... read more
