Have you ever wondered how we can use the sun's rays to power our homes and schools? Meet Dr. Martin Green, a brilliant scientist who's as amazing as the sun! He is called the
Dr. Martin Green was a curious kid. He lived in Sydney, Australia and loved exploring nature's wonders. He wondered if he could use the sun's rays to create electricity and help the Earth. As Dr. Green grew up, his curiosity turned into a quest to find a way to turn sunlight into electricity. He discovered special "solar cells" that could do just that! These tiny heroes could change sunlight into clean and green energy.
The Birth of a Solar Superhero
As he continued his studies, Dr. Green's interest in solar science grew. During his PhD work in Canada, he stumbled upon something amazing - a special type of solar cell called tunnel oxide passivated contacts (TOPCon) with excellent energy conversion properties. This discovery excited him and deepened his resolve to explore solar energy further.
In 1974, after completing his PhD at McMaster University, Dr. Green returned to his homeland and joined the University of New South Wales (UNSW) in Sydney. There, he initiated the Solar Photovoltaics Group, a team of bright minds determined to unlock the secrets of solar power.
Driven by their passion for renewable energy, the team at UNSW worked tirelessly to develop silicon solar cells with greater efficiency. They aimed to capture more sunlight and convert it into electricity, making solar power a fantastic alternative to traditional energy sources.
Breaking World Records
In 1983, the Solar Photovoltaics Group achieved something incredible- they set a new world efficiency record for silicon solar cells. Their innovative work resulted in a solar cell that could convert a remarkable 18 per cent of sunlight into electrical energy directly. This was the first of 18 separate records from his team over the next 30 years, increasing silicon cell efficiency by over 50% in relative terms during the process.
It was a moment of triumph, as it meant that solar energy could become a practical and efficient source of power.
But Dr. Green and his team didn't stop there. They continued their journey and broke more efficiency records. They pushed the boundaries, reaching efficiencies of 20 per cent in 1985, 24 per cent in 1994, and 25 per cent in 2008. Their solar cell technology, known as PERC (Passivated Emitter and Rear Cell), became the backbone of modern solar power, accounting for 90 per cent of global solar cell production.
"If you bought a solar panel recently, it will most likely have UNSW PERC technology used in it," Dr. Green proudly declares.
Inspiring Solar SuperHeroes of Tomorrow
Dr. Green's passion for renewable energy extended beyond research. He loves to share his knowledge and inspire others, especially young minds like you! He has written several books on solar cells, making complex science easy to understand for everyone.
He has also made a substantial impact on engineering education. His highly cited book, "Solar Cells: Operating Principles, Technology, and System Applications," has become a cornerstone in the field.
He also played a crucial role in introducing the world's first photovoltaic undergraduate engineering degree program in 2000, paving the way for future solar engineers to continue his work. His goal is to nurture a new generation of solar heroes who will carry forward the mission of a cleaner and greener world.
Over the years, he supervised over 120 PhD students, many of whom have gone on to achieve great things in their careers. One of his most famous students is Dr. Zheng Rong-Shi, who set up solar cell manufacturing in China. Dr. Zheng's success with Sunman Energy became a turning point for the entire solar industry, making solar panels more affordable for everyone.
Dr. Green's former students have made significant contributions to the solar industry, reducing solar costs and making solar energy a powerful weapon in the fight against climate change.
Through his pioneering efforts, Dr. Green has paved the way for the "third generation" of photovoltaics, which explores exciting new ways to make solar energy even more efficient and sustainable.
Awards and Legacy
For his outstanding contributions, Dr. Green has received numerous prestigious international awards. These include the Australia Prize, the Japan Prize, the Millennium Technology Prize, and the Queen Elizabeth Prize for Engineering. His work has been recognized globally, inspiring others to follow in his solar-powered footsteps.
Dr Martin Green's journey from a curious kid in Sydney to a world-renowned solar superhero shows the amazing impact of curiosity and hard work. His work in renewable energy has changed the solar industry, making clean energy a reality for our planet's future.
With Dr. Green as our guiding star, let's continue the journey of solar brilliance, embracing renewable energy and becoming solar superheroes ourselves! Together, we can light up the world and protect our precious Earth.
