Copolymer?Templated Nickel Oxide for High?Efficiency Mesoscopic Perovskite Solar Cells in Inverted Architecture

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...

Nanocarbons for mesoscopic perovskite solar cells

Degradation 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 ...

Sprayed P25 scaffolds for high-efficiency mesoscopic perovskite solar cells.

Uniform, thickness-controllable and large-size mesoscopic TiO2 films based on commercial P25 nanoparticles are prepared by a spray method, which have been applied in the perovskite solar cells, achieving a high efficiency of 16%. This spray method shows promising application in the large-scale production of mesoscopic solar cells.

Overcoming the Limitations of Sputtered Nickel Oxide for High‐Efficiency and Large‐Area Perovskite Solar Cells

Perovskite solar cells (PSCs) are one of the promising photovoltaic technologies for solar electricity generation. NiO x is an inorganic p-type semiconductor widely used to address the stability issue of PSCs. Although high efficiency is obtained for the devices employing NiO x as the hole transport layer, the fabrication methods have yet to be demonstrated for industrially relevant manufacturi...
