‘World-changing’ indoor solar cells offer everlasting electronics
Harvesting energy from any light source – even a candle – a new generation of ultra-durable and flexible solar cells means devices never need charging. ‘Our grandchildren will laugh that we had cables,’ one industry pioneer tells Anthony Cuthbertson
Sweden may seem an unlikely location for a solar revolution, but the lack of light during the winter months was one of the reasons for Exeger co-founder Giovanni Fili to look beyond the Sun as the sole source of power for a photovoltaic cell. “It works in any light condition, it’s more durable than any other solar cell in the world, it’s easy to manufacture, and it can imitate any surface – leather, carbon fibre, wood, brushed steel. The Korean electronics giant has made switching from alkaline batteries to photovoltaic energy a priority in order to reach sustainability targets, claiming it could reduce its greenhouse gas emissions by around 6,000 tons per year.
