p-type Mesoscopic Nickel Oxide/Organometallic Perovskite Heterojunction Solar Cells
In this article, we present a new paradigm for organometallic hybrid perovskite solar cell using NiO inorganic metal oxide nanocrystalline as p-type electrode material and realized the first mesoscopic NiO/perovskite/[6,6]-phenyl C61-butyric acid methyl ester (PC61BM) heterojunction photovoltaic device. The photo-induced transient absorption spectroscopy results verified that the architecture i...
متن کاملDegradation Kinetics of Inverted Perovskite Solar Cells
We explore the degradation behaviour under continuous illumination and direct oxygen exposure of inverted unencapsulated formamidinium(FA)0.83Cs0.17Pb(I0.8Br0.2)3, CH3NH3PbI3, and CH3NH3PbI3-xClx perovskite solar cells. We continuously test the devices in-situ and in-operando with current-voltage sweeps, transient photocurrent, and transient photovoltage measurements, and find that degradation ...
متن کاملApplication of Au@SiO2 Plasmonic Nanoparticles at Interface of TiO2 Mesoporous Layers in Perovskite Solar Cells
To investigate the plasmonic effect in perovskite solar cells, the effect of depositing Au@SiO2 nanoparticles on the top and the bottom of mesoporous TiO2 layers was studied. First, Au@SiO2 nanoparticles were synthesized. The particles were then deposited at the different interfaces of mesoporous TiO2 layers. Although the two structures show approximately similar optical absorption, only cells ...
متن کاملStable and durable CH3NH3PbI3 perovskite solar cells at ambient conditions.
Degradation of metal-organic halide perovskites when exposed to ambient conditions is a crucial issue that needs to be addressed for commercial viability of perovskite solar cells (PSCs). Here, a concept of encapsulating CH3NH3PbI3 perovskite crystals with a multi-functional graphene-polyaniline (PANI) composite coating to protect the perovskite against degradation from moisture, oxygen and UV ...
متن کاملSequentially Vapor-Grown Hybrid Perovskite for Planar Heterojunction Solar Cells
High-quality and reproducible perovskite layer fabrication routes are essential for the implementation of efficient planar solar cells. Here, we introduce a sequential vapor-processing route based on physical vacuum evaporation of a PbCl2 layer followed by chemical reaction with methyl-ammonium iodide vapor. The demonstrated vapor-grown perovskite layers show compact, pinhole-free, and uniform ...
