Summary: Iodide migration causes degradation of the perovskite solar cells. Here, we observe the direct migration of iodide into the hole-transport layer in a device. We demonstrate that ultrathin room temperature atomic layer-deposited Al2O3 on the

Emerging photovoltaic technologies are expected to have lower environmental impacts during their life cycle due to their extremely thin-film technology and resulting material savings. The environmental impacts of four emerging photovoltaics were inve

The investigation of hot-pressed methylammonium lead bromide (MAPbBr3) is reported. The as-prepared materials consisted of microcrystallites (30–500 μm size) with a non-centrosymmetric pseudo-cubic tetragonal crystalline structure (P4 mm space gro

In this contribution, we investigate the solid electrolyte interface (SEI) layers’ composition depending on the spatial location within LiCoO2 composite cathode of a commercial Li-Ion battery. The surface chemistry is analyzed by X-ray photoelectro

Currently, Me-N-C catalysts are the most prominent alternative to Pt/C catalysts for the oxygen reduction reaction in acidic media. It is well known that the achievable activity and selectivity strongly correlates with the nature of metal species. Ho

Using plated contacts, many of the challenges of metallizing high-efficiency n-type solar cells can be overcome. Very low resistivity contacts on boron emitters are hard to achieve by standard screen printing, and voltage reductions of up to 30 mV wi
