• This paper reports the external quantum efficiency (EQE) of encapsulated screen‐printed crystalline silicon solar cells, where the encapsulation includes a layer of luminescent down‐shifting (LDS) molecules. At wavelengths less than 400 nm, the inclusion of the LDS molecules increases the EQE from near zero to, at most, 40%. The increase in EQE corresponds to a rise in short‐circuit current density of 0·37 ± 0·13 mA/cm2 under the AM1‐5g spectrum. Copyright © 2008 John Wiley & Sons, Ltd. The quantum efficiency of screen‐printed silicon solar cells is measured after encapsulation. At short wavelegths, the quantum efficiency is 20–40% when the encapsulation includes luminescent organic dyes, and 0% when it does not. At best, the difference in quantum efficiency equates to a 1% increase in short‐circuit current under the AM1‐5g spectrum.
