A two-resonance tapping cavity for an optimal light trapping in thin-film solar cells
(2017-09-20)
Article
Open AccessAn optimal photon absorption in thin film photovoltaic technologies can only be reached by effectively trapping the light in the absorber layer provided a considerable portion of the photons is rejected or scattered out ... -
Circumventing UV light induced nano-morphology disorder to achieve long lifetime PTB7-Th:PCBM based solar cells
(Wiley, 2017-07-17)
Article
Open AccessLarge area flexible electronics rely on organic or hybrid materials prone to degradation limiting the device lifetime. For many years, photo-oxidation has been thought to be one of the major degradation pathways. However, ... -

Ergodic Light Propagation in a Half-Cylinder Photonic Plate for Optimal Absorption in Perovskite Solar Cells
(2019-05-17)
Article
Open AccessIn an optical medium slab, a randomization of the interfaces will lead to an ergodic light propagation, implying a kind of light trapping that sets an upper limit for a broadband absorption enhancement factor. However, in ... -
Inverse Optical Cavity Design for Ultrabroadband Light Absorption Beyond the Conventional Limit in Low-Bandgap Nonfullerene Acceptor–Based Solar Cells
(2019-05-23)
Article
Open AccessIn the subwavelength regime, several nanophotonic configurations have been proposed to overcome the conventional light trapping or light absorption enhancement limit in solar cells also known as the Yablonovitch limit. It ... -
Light harvesting at oblique incidence decoupled from transmission in organic solar cells exhibiting 9.8% efficiency and 50% visible light transparency
(2020-01-01)
Article
Open AccessFor many years, it has been recognized that potential organic photovoltaic cells must be integrated into elements requiring high transparency. In most of such elements, sunlight is likely to be incident at large angles. ... -
Monolithic CIGS-Perovskite Tandem Cell for an Optimal Light Harvesting Without Current Matching
(ACS, 2017-03-23)
Article
Open AccessWe present a novel monolithic architecture for optimal light harvesting in multijunction thin film solar cells. In the configuration we consider, formed by a perovskite (PVK) cell overlying a CIGS cell, the current extracted ... -

Relation between Fluorescence Quantum Yield and Open-Circuit Voltage in Complete Perovskite Solar Cells
(Wiley, 2020-04)
Article
Open AccessBringing the Voc of a perovskite solar cell toward its radiative value, corresponding to a 100% external fluorescence quantum yield (QY) of the cell, has been pursued to reach the highest performance photovoltaic devices. ...
