Professor Green – often described as the “father of modern photovoltaics” – is recognized for his pioneering efforts and groundbreaking achievements in high conversion efficiency of silicon photovoltaic materials as well as leading the invention and development of the passivated emitter and rear contact (PERC) solar cell.

PERC technology improved the quality of both the top and rear surfaces of standard silicon solar cells, resulting in greater and more efficient generation. This allowed more electricity to be generated from sunlight, lowering costs and increasing the adoption of sustainable solar energy worldwide.

The technology breakthrough helped increase the conversion efficiency of standard solar cells by over 50% in relative terms from 16.5% in the early 1980s to 25% in the early 2000s. Through successive improvements to cell design and fabrication, Green and his team held the record for silicon cell efficiency for 30 of the past 40 years.

PERC currently dominates solar cell production worldwide. Together with Tunnel Oxide Passivated Contact (TOPCon) cells – first demonstrated by Green’s research group at UNSW – the cells account for more than 90% of solar cells manufactured in the world today at a sales value exceeding $100 billion USD to date.

Development of this technology also resulted in the training of a generation of students who, with Green’s support, applied their acquired skills to establish solar cell manufacturing in Asia. These achievements are unique globally in both the quantum of efficiency improvement and the share of manufacturing capacity.

Professor Green is thrilled to be awarded the Leigh Ann Conn Prize. “From the start of my career, I was determined to do something that would make a difference in the world. I am very proud that, through the efforts of my team and countless others, we now have low-cost solar as a means for reducing the impact of climate change while, at the same time, reducing the cost of energy generation, something not widely thought possible only a decade ago,” said Green.

UNSW’s acting Vice-Chancellor and President Professor George Williams congratulated Professor Green on winning the Prize.

“Martin is a brilliant engineer whose leadership and accomplishments have led to the creation and development of the world’s solar manufacturing industry. His life’s work benefits people around the globe every day and is arguably our biggest weapon to combat global warming and climate change. Everyone at UNSW is proud to celebrate this well-deserved honour with him,” Williams said.

In March 2024, Green will give a public lecture in Louisville about his winning work and achievements, trials and tribulations. He will receive the Conn Prize medal and $50,000 award at a formal ceremony.

“Professor Martin Green is a true pioneer in the field of photovoltaics,” said University of Louisville President Kim Schatzel, who will confer the award. “His work in solar cell technology is of great importance worldwide, and it is an honor to bestow upon him the Leigh Ann Conn Prize.”

The UofL prize is named for the late daughter of Hank and Rebecca Conn, who were university alumni, supporters and the prize benefactors. Their vision to create a legacy in honor of Leigh Ann celebrates scientists with the fortitude, patience, and resiliency to endure renewable energy technology innovation and translation into the marketplace, where impact occurs.

Nominations for the 2025 Leigh Ann Conn Prize competition close Dec. 31, 2024. Criteria and instructions are found at . For more information, contact Andrew Marsh at 502-852-8597 or LeighAnnConnPrize@louisville.edu.

The team also includes members from the American University of Sharjah, Higher Colleges of Technology and American University in Dubai, all located in the United Arab Emirates.

Team “Desert Phoenix” will compete with 14 other teams from around the world to design, build and operate sustainable models of solar-powered homes, with a focus on protecting the environment, taking into consideration the climate and culture of the region. 

These homes will be assembled at the SDME competition site in Mohammed bin Rashid Al Maktoum Solar Park in Dubai. The multidisciplinary teams compete in 10 different categories, ranging from best architecture and engineering to energy production for heating and cooling, while gaining invaluable real-world experience in a growing global industry.

Organized by Dubai Electricity and Water Authority under the patronage of His Highness Sheikh Hamdan bin Mohammed bin Rashid Al Maktoum, crown prince of Dubai and chairman of Dubai Executive Council, SDME is the largest solar decathlon competition for international universities. Its goal is to involve youth in sustainable development processes and encourage them to use their creativity to develop solutions that support global efforts to reduce the negative impacts of climate change.

“Conn Center’s intention is to forge partnerships with many other institutions and inspire students to address the global energy challenge,” said Mahendra Sunkara, director of the of the at UofL.

The team hopes to develop and introduce low-cost housing solutions with very low energy bills for low-income urban and rural living. Their design seeks to provide cost-effective, zero-net energy residential space with a low environmental and actual footprint to improve the affordability of these spaces, especially in the current world economy.

Each of the four universities will focus on a specific area in the project. Team members at UofL are focusing on the building structure, building envelope and energy conservation. AUS is focused on smart solutions and water management, AUD on architectural design of the house and HCT on civil engineering, especially water conservation.

“This multinational effort allows us to explore varied technologies and design philosophies to address common problems, with significant potential for improvement in performance and acceptance in all our countries,” said W. M. McGinley, professor of civil engineering at , who will lead the UofL team group, along with Sunkara.

“World-class competitions such as this are of immense benefit to students as they enable them to implement theories learned in classes in a highly practical and experiential environment, by way of innovative and cutting-edge designs and concepts, which will help to solve global housing issues,” said Tariq Khan, assistant professor in mechanical engineering and team leader at HCT. “Our eco-friendly house will be the best blend of architecture, reflecting local heritage and innovative engineering excellence with a focus on sustainability.”

The project also provides an opportunity to engage the community in support of the project.

“Each of the universities will reach out to the various institutions in the community according to their area of expertise to support the project, whether through technical expertise, funding or equipment. We aim to strengthen our community engagement and give back to society. The project will not only positively impact the community but will also increase the country’s energy security and make it less dependent on fossil fuel,” said Mostafa Shaaban, associate professor in electrical engineering and AUS project team leader.
