Luminescent solar concentrators (LSCs) are light-management devices and used for harvesting concentrating light from a large area to their edges. Being semitransparent devices, LSCs show great promise future utilization in glass walls of urban buildings as environmentally friendly photovoltaic power plants. The development cheap eco-safe materials, the extension LSC operation range, enhancement optical efficiency key challenges, which need be solved order transform energetically passive into self-sustainable units. Herein, (64 cm2) tandem fabricated using entirely eco-friendly highly emissive blue, green, red carbon dots is demonstrated, with an internal quantum 23.6% external 2.3%, while maintaining high transparency across visible spectrum. This opens up new direction application advanced technologies.
