Multi-porous-layered-electrode perovskite solar cells (MPLE-PSCs) have been fabricated for the outer-space application, which should have the stability at 130 degrees C. After selection of sealing glue compounds, the thermal stability of MPLE-PSCs...

The effect of atomic hydrogen exposure on hydrogenated amorphous carbon (a-C:H) films was investigated by X-ray photoelectron spectroscopy (XPS). From the dependence of the wide-scan XPS spectra of an a-C:H film on atomic hydrogen exposure, it was...
Improving stability has become one of the most important objectives in the practical application of perovskite photovoltaics. Here, we develop encapsulated mesoporous-carbon perovskite solar mini-modules that retain more than 92% of their initial ...
We applied room-temperature photoluminescence (PL) spectroscopy for the compositional engineering of a CH3NH3Pb(Cl,I)(3) light harvester in an alloy-based perovskite solar cell. This spectroscopic characterization determines the optimal Cl concent...

In this work we compare seven different types of natural and synthetic graphite particles and examine how their integration into the cathode of carbon-based perovskite solar cells (C-PSCs) is influencing their opto-electronic properties. By combin...
