Back-contacted emitter GaAs solar cells [PDF]

open access: yesApplied Physics Letters, 1990
A new device structure to improve the performance of concentrator GaAs solar cells is described and the first experimental results are reported. The reason for such an improvement relies on a drastic reduction of the shadowing and series resistance losses based on the possibility of back contacting the emitter region of the solar cell. The experimental

Metal diffusion barriers for GaAs solar cells [PDF]

open access: yesPhysical Chemistry Chemical Physics, 2017
Accelerated Ageing Testing (AAT) was used to assess the barrier potential of Ti, Ni, Pd and Pt. At a test temperature of 250 °C Ni offers the largest barrier potential. Based on TEM images and phase diagrams a barrier mechanism is proposed.
