Scientists from the Universities of Cambridge and Bristol have found a way to create plastic semiconductor nanostructures that absorb light and transport its energy 20 times further than has been previously observed, paving the way for more flexible and more efficient solar cells and photodetectors.
Researchers have shown that defects in the molecular structure of perovskites – a material which could revolutionise the solar cell industry – can be “healed” by exposing it to light and just the right amount of humidity.
Researchers have demonstrated how a non-toxic alternative to lead could form the basis of next-generation solar cells.
Aditya Sadhanala wanders over to the wall, turns a pulley, and a wooden box about a metre squared swings up and away. Below it gleams an array of carefully positioned lasers, deflectors and sensors surrounding a piece of glass no bigger than a contact lens. He flips a switch and creates a ‘mirage’.
Green wall technology and semi-transparent solar panels have been combined to generate electrical current from a renewable source of energy both day and night.
Perovskite materials are the newest contender for breaking the silicon ceiling in solar cell technology. But they don’t just absorb light. Cambridge researchers have found they emit it like a laser, opening up an entirely new field of applications.
