High-performance piezo-phototronic solar cell based on two-dimensional materials

Monolayer MoS2 shows piezoelectric and semiconductor properties in recent experiments, which have been used for nanogenertor and piezotronic transistor. Two-dimensional piezoelectric semiconductor can be applied for piezo-phototronic solar cell. The modulation by piezo-phototronic effect can enhance the performance of monolayer MoS2 solar cells.182
