Assessing the potential of inversion layer solar cells
Based on highly charged dielectric nanolayers
The production and performance of inversion layer silicon solar cells is investigated in this paper published by IPSS.
An ion-injection technique is used to obtain highly charged dielectric nanolayers. Charge concentrations as high as 2 x 1013 cm-2 is demonstrated, which could lead to an efficiency of 24.8% on 10 Ω cm silicon.
Better performance is expected with enhanced passivation, higher charge densities, and optimal negative charge at rear dielectric.
