Incorporating guanidinium into perovskite solar cells stabilizes their efficiency at 19% for 1,000 hours under full-sunlight testing conditions. With the power-conversion efficiency of silicon solar cells plateauing around 25%, perovskites are now ideally placed to become the market’s next generation of photovoltaics...
