Defect‐rich black titanium dioxide (B‐TiO2) has been extensively studied over the past decade due to its enhanced photoelectrochemical efficiency compared to titanium dioxide (TiO2), which is known for its outstanding photocatalytic stability. So

Fuel cell electric vehicles (FCEVs) can be used during idle times to convert hydrogen into electricity in a decentralised manner, thus ensuring a completely renewable energy supply. In addition to the electric power, waste heat is generated in the fu

Radiative cooling to subambient temperatures can be efficiently achieved through spectrally selective emission, which until now has only been realized by using complex nanoengineered structures. Here, a simple dip-coated planar polymer emitter derive

Fabry-Perot-type resonant nanocavities allow for broadband enhancement of light absorption in ultrathin absorber layers. By introducing a switchable mirror, these thin film structures can be used as unique optical devices enabling interesting applica
In this contribution, we study the effects of optical switching on quantum confinement of a semitransparent solar cell based on an ultrathin amorphous germanium absorber placed inside a resonant nanocavity. The optical switching of the cavity is base

In this work, we report a proof-of-concept for an ultrathin multiple quantum wells (MQW) solar cell based on silicon (barrier)/germanium (QW) heterostructures integrated as a subwavelength photonic resonator below 50 nm. The multiplication of the QWs

The aim of this study is to evaluate the potential of using standard photovoltaic (PV) modules on board of cruise ships to increase the share of renewable energies in the total energy demand. Due to the limited space available, also partial shaded ar
