Plasmonic quantum dot solar cells for enhanced infrared response

Feng Lu, Hao; Mokkapati, Sudha; Fu, Lan; Jolley, Greg; Hoe Tan, Hark; Jagadish, Chennupati

Description

Enhanced near infrared photoresponse in plasmonic InGaAs/GaAs quantum dotsolar cells (QDSC) is demonstrated. Long wavelength light absorption in the wetting-layer and quantum-dot region of the quantum dotsolar cell is enhanced through scattering of light by silver nanoparticles deposited on the solar cellsurface.Plasmonic light trapping results in simultaneous increase in short-circuit current density by 5.3% and open circuit voltage by 0.9% in the QDSC, leading to an overall efficiency...[Show more]
