This work aims to understand the spin-coating growth process of BiVO4 photoanodes from a photon absorption and conversion perspective. layers with thicknesses ranging 7 48 nm role thin (<5 nm) SnO2 hole-blocking layer have been studied. The internal absorbed photon-to-current efficiency (APCE) is found be nonconstant, following specific dependence charge separation extraction on increasing thickness. APCE variation thickness key for precise computational simulation light propagation in based...
Thin films containing monometallic (Ag,Au) and bimetallic (Ag–Au) noble nanoparticles were dispersed in TiO2, using reactive magnetron sputtering post-deposition thermal annealing. The influence of metal concentration annealing the (micro)structural evolution was studied, its correlation with localized surface plasmon resonance (LSPR) enhanced Raman spectroscopy (SERS) behaviours evaluated. Ag/TiO2 presented columnar to granular microstructures, developing Ag clusters at for higher...
Bringing the V oc of a perovskite solar cell toward its radiative value, corresponding to 100% external fluorescence quantum yield (QY) cell, has been pursued reach highest performance photovoltaic devices. Therefore, much research focused on maximizing QY active layer isolated from rest layers. However, such quantity does not often correlate with following ideal diode relation. Herein, QYs complete FA 0.8 MA 0.2 PbI 3− y Br cells are reported, ranging 0.1% 3%, and compared their s, 1 1.13...

A semiconductor/solar cell tandem structure has been theoretically demonstrated as a viable path achieve an efficient direct transformation sunlight into chemical energy. However, compact designs exhibiting indispensable optimally balanced light absorption have not demonstrated. In current work, we design...
Abstract Perovskite based photovoltaic (PV) cells are unique in combining low open‐circuit voltage losses with a broad bandgap tunability. This makes them an ideal PV cell to recycle photons back into electrical power variety of illumination systems or light emitting devices. Here, advantage these features is taken and wide (WBG) perovskite incorporated devices suitable for display demonstrate high yield stray recycling electricity up 37.5% conversion efficiency. The specific device...
Solar cells based on perovskite compounds have displayed remarkable efficiency, with a focus enhancing parameters like short-circuit current (Jsc) and open-circuit voltage (Voc) to maximize their performance. However, Voc is closely related recombination optical effects an important parameter affecting energy conversion efficiency. To exploit the full potential of solar cells, photonic management emerges as key strategy. This study delves into strategies for improving overall efficiency cells.
Energy efficiency in many illumination devices is far from optimal. For instance, liquid crystal displays, a large fraction of the emitted light lost provided absorbing polarizers are used for image formation. Herein, light‐guiding structure to achieve diffuse polarized emission top guide, combined with harvesting and conversion back into electricity unwanted polarization proposed. Key achieving such double goal use half‐cylinder photonic plate an ergodic light‐guided propagation...
