Solar energy, past, present & future

Dr Paul Coxon


Solar photovoltaics have spread widely in recent years as costs have plummeted. They make up less than 1% of the electricity market today but could be the world’s cheapest energy source by 2030. I will give a gentle introduction on the history of solar energy, how solar cells work, and how scientists are now harnessing natural structures and materials to make them more efficient.
