摘要：
Low-energy photons, which are not used by a solar cell, can be converted to higher-energy photons by photon upconversion. The figure-of-merit of upconvertors, J(UC) is given in mA cm(-2) under 1 sun excitation conditions. A device-relevant J(UC) should not be less than 0.1 mA cm(-2). However, to date, the highest J(UC) reported is in the 10(-2) mA cm(-2) range. In this Perspective, we analyze the shortcomings of previously reported devices and unfold a roadmap toward device -relevant, high-efficiency upconvertors.
