The presence of toxic lead (Pb) remains a major obstruction to the commercial application perovskite solar cells.

Under mild mechanical pressure, halide perovskites show enhanced optoelectronic properties. However, these improvements are reversible upon decompression, and permanent enhancements have yet to be realized.
