How Much Better Can Solar Get? Deep Dive Australia 08: Martin Green
Solar was once dismissed as a marginal technology. Today, it is transforming the global energy system, and few people have done more to make that possible than Professor Martin Green. Innovations developed by Green and his research group can now be found in over 90% of all the solar panels in use today
One of the pioneers of modern solar power, Green’s research has helped make solar panels dramatically more efficient and cheaper to produce. He joins Michael Liebreich to discuss how he got into solar, the breakthroughs that helped drive its extraordinary rise, and the remarkable story of how research carried out at an Australian university helped create the global solar manufacturing industry. They also look at where solar goes next, and whether the next generation of technology can make it even more powerful.
