Luminescent solar concentrators (LSCs) can be used to concentrate both diffuse and direct sunlight without the need of complex light tracking systems, thus facilitating photovoltaic cells to harvest more solar energy, while reducing the material costs of solar cells. In order to manufacture a successful LSCs, there are two requirements which are reabsorption and scattering. Through a one-step fast microwave-assisted approach, aurum nanoclusters (AuNCs) are synthesized using Glutathione as a precursor and Chloroauric acid as a doping. AuNCs has a large Stokes shift to reduce the probability of absorption. Moreover, the AuNCs/Polymer composites are put in the middle of two glass to become a smooth LSC.
