We propose a design for a concentrated photovoltaic (CPV) module with features that can capture both direct and diffuse sunlight. This approach uses a luminescent solar concentrator (LSC) sheet that includes quantum dots, and a tailored optical coating that enhances concentration and delivery of sunlight to the micro-PV cells. In addition, the light not captured by the quantum dots impinges on a tandem solar cell beneath the LSC sheet. The design of the LSC focuses on lowering the number of expensive micro-PV cells needed within the concentrator waveguide, thus reducing system costs while maintaining high efficiency. The design also allows the module to be effective without a tracking system, making it attractive to all PV markets.
