Nanoscale mapping of chemical composition in organic-inorganic hybrid perovskite films

Ulf Anders Hagfeldt, Silver Hamill Turren Cruz, Rodrigo Szostak

Lead-based organic-inorganic hybrid perovskite (OIHP) solar cells can attain efficiencies over 20%. However, the impact of ion mobility and/or organic depletion, structural changes, and segregation under operating conditions urge for decisive and more accu ...

Optimized Design of Silicon Heterojunction Solar Cells for Field Operating Conditions

Christophe Ballif, Mathieu Gérard Boccard, Jan Haschke, Jean Cattin, Brahim Aissa, Olivier Denis Dupré

Solar modules are currently characterised at standard test conditions (STC), defined at 1000 W/m2 and 25 °C. However, solar modules in actual outdoor operating conditions typically operate at lower illumination and higher temperature than STC, which signif ...

InAlN underlaver for near ultraviolet InGaN based light emitting diodes

Nicolas Grandjean, Jean-François Carlin, Mauro Mosca, Camille Haller, Rolf Erni

We report on InAlN underlayer (UL) to improve the efficiency of near ultraviolet (NUV) light emitting diodes (LEDs). While InGaN UL is commonly used in high-efficiency blue LEDs it may absorb light for shorter wavelengths. InAlN lattice-matched to GaN exhi ...

Extraction of p-n junction properties and series resistance in GaAs nanowire-based solar cells using light concentration

Anna Fontcuberta i Morral, Dmitry Mikulik, Pablo Romero Gómez, Ian Nachemson

Series resistance in solar cells limit their maximum conversion efficiency and thus should be minimized. Generally, such losses originate from deficiencies at the contact or absorber level. Quantifying them is the first step for tackling its reduction. In ...

Influence of Body-Implanted Capsule Dimensions and Materials on Achievable Radiation Efficiency

Anja Skrivervik, Denys Nikolayev

Fundamental bounds on achievable radiation efficiency serve as the design quality gauge, facilitate the choice of the antenna type considering the available dimensions, and provide simple rules to check the feasibility of a given design. This study quantif ...
