The square nanowire array solar absorbers are inversely designed using the Particle Swarm Optimization algorithm to maximum short-circuit current density. The results shows that absorptance of device exhibits a flatter trend which is due to the superposition of absorption peaks with different spacing nanowires. Furthermore, there is a notable increase in absorption at longer wavelengths, owing to the enhanced light trapping effect. The ultimate photoelectric conversion efficiency of the non-uniform nanowire array can reach 33.97%. This work provides a new approach for the design of novel high-efficiency solar devices.

摘要

The square nanowire array solar absorbers are inversely designed using the Particle Swarm Optimization algorithm to maximum short-circuit current density. The results shows that absorptance of device exhibits a flatter trend which is due to the superposition of absorption peaks with different spacing nanowires. Furthermore, there is a notable increase in absorption at longer wavelengths, owing to the enhanced light trapping effect. The ultimate photoelectric conversion efficiency of the non-uniform nanowire array can reach 33.97%. This work provides a new approach for the design of novel high-efficiency solar devices.
