Optical adsorption, band alignment and power-conversion efficiency. (a) The optical adsorption of c-silicyne at the ε=0 and 0.09 strains. (b) The band alignment between MoS 2 and strained c-silicyne sheets. (c) Calculated power-conversion efficiency as a function of the donor bandgap and conduction band offset, in which the values of c-silicyne/MoS 2 system are marked as stars.
