In this review, we present important concepts to describe inorganic–organic interfaces in
hybrid solar cells. We discuss the formation of hybrid interfaces, provide an introduction to …

Third generation photovoltaics are inexpensive modules that promise power conversion
efficiencies exceeding the thermodynamic Shockley–Queisser limit, perhaps by using up-or …

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 …

The color-tunable upconversion (UC) emission and optical temperature sensing based on
non-thermal coupled levels (NTCL) were observed from the Yb 3+/Ho 3+ codoped Lu 3 NbO …

Upconversion is a photon-management process especially suited to water-splitting cells that
exploit wide-bandgap photocatalysts. Currently, such catalysts cannot utilize 95% of the …

We present a red-to-blue upconversion system based on triplet–triplet annihilation in a solid-
state film configuration that significantly enhances the photocurrent of a model solar cell …

Solar cell or photovoltaic technology consists of devices that generate electrical energy from
electromagnetic radiation, most often from the sun. Crystalline silicon (Si) technology is a …

Hitherto, great strides have been made in the development of organic systems that exhibit
triplet–triplet annihilation-induced photon-energy upconversion (TTA-UC). Yet, the exact role …

Photon upconversion based on the process of triplet–triplet annihilation in a system of
organic donor and acceptor molecules has been attracting increasing attention because it …
