Spray-On Solar

The video discusses the potential of solar power and the challenges in making it cost-effective and efficient. It highlights the work of Brian Korgel and his team at the University of Texas, who are developing spray-on solar cells as a flexible and cheaper alternative to traditional solar panels. These cells use nanocrystals and can be applied like ink. The current efficiency of these cells is around 3%, but they need to reach 10% for commercial viability. The video concludes with the excitement surrounding this innovative approach to sustainable energy.
