Abstract

We have investigated the potential use of HITCI molecules in PMMA for use as a luminescent solar concentrator (LSC) in a photovoltaic (PV) window, where the LSC layer is used to direct the infrared solar radiation towards silicon solar cells located inside the window’s frame. On small sample with various HITCI concentrations, Stokes shift in the range of 70nm to 80nm have been measured. The LSC layer as an IR waveguide shows a decay length of 12.9mm-1. Implementation on a real size window (20cm x 20cm) shows only marginal improvement compared to a similar window without any LSC layer.
