- *Abstract
-
Recent advances in the field of photovoltaic technology have enabled production of low-cost, high-efficiency solar cells. However, these devices are based on lead-containing perovskite minerals, which present a concern from an environmental point of view. Northwestern University researchers were able to solve this problem by designing and manufacturing a solar cell without the use of lead. Their novel methylamonium tin halide perovskite material is not only lead-free, but also features the ideal optical band gap, which makes it an efficient light harvesting material. This disruptive technological advance will further solar cell research by removing a critical concern about detrimental effects to the environment.
