“…Solar simulating light (SSL) has been frequently employed for evaluating the performance of photovoltaic cells (Senadeera et al, 2003) or photocatalysts (Yu et al, 2009;Sakai et al, 2016). Since the photovoltaic cells and photocatalysts are mostly sensitive to ultraviolet (UV) and visible (VIS) lights regions, most SSL are designed to reproduce the spectra of solar ray in these regions.…”
