Apart from costs, one of the keys to the market introduction of the fluorescent solar concentrator (FSC) is its outdoor lifetime, which up to now, is limited a few years by the lifetime of the fluorescent dye or quantum dot. This study shows that omitting the dye or quantum dot still can give power conversion efficiencies (PCE), which are comparable to, or even larger than that of the FSC. This can be done by using a special type of bottom mirror. It is shown that a PCE of 4.5% can be achieved.
