Efficient planar heterojunction perovskite solar cells by vapour deposition
It is shown that perovskite absorbers can function at the highest efficiencies in simplified device architectures, without the need for complex nanostructures.
Charge-carrier dynamics in vapour-deposited films of the organolead halide perovskite CH3NH3PbI3-xClx
We determine high charge-carrier mobilities ≥ 33 cm2 V−1 s−1 and bi-molecular recombination rates about five orders of magnitude below the prediction of Langevin's model for vapour-deposited
Charge selective contacts, mobile ions and anomalous hysteresis in organic-inorganic perovskite solar cells
High-efficiency perovskite solar cells typically employ an organic–inorganic metal halide perovskite material as light absorber and charge transporter, sandwiched between a p-type electron-blocking
Charge carrier recombination channels in the low-temperature phase of organic-inorganic lead halide perovskite thin films
The optoelectronic properties of the mixed hybrid lead halide perovskite CH3NH3PbI3−xClx have been subject to numerous recent studies related to its extraordinary capabilities as an absorber material
Homogeneous Emission Line Broadening in the Organo Lead Halide Perovskite CH3NH3PbI3-xClx.
Investigating processes for high-quality vapor-deposited films of CH3NH3PbI3-xClx using time- and excitation-energy dependent photoluminescence spectroscopy shows that the PL spectrum is homogenously broadened with a line width of 103 meV most likely as a consequence of phonon coupling effects.
Recent efficient strategies for improving the moisture stability of perovskite solar cells
In the past few years, hybrid organic–inorganic perovskite solar cells (PSCs) have attracted much attention due to their excellent photovoltaic performance and extremely low fabrication costs. The
Distinctive Supercapacitive Properties of Copper and Copper Oxide Nanocrystals Sharing a Similar Colloidal Synthetic Route
CuO and Cu2O are non‐noble transition metal oxide supercapacitive materials with high theoretical specific capacitances above 1800 F g−1. In this work, by adjusting organic additives of a colloidal
Tailored dimensionality to regulate the phase stability of inorganic cesium lead iodide perovskites.
The concept of using large radius cations in the 3D perovskite system provides a new perspective to further enhance the phase stability while retaining the device performance.
Influence of Interface Morphology on Hysteresis in Vapor‐Deposited Perovskite Solar Cells
Hysteresis in the current–voltage characteristics of vapor-deposited perovskite solar cells is shown to originate from an amorphous region of CH3NH3PbI3 at the interface with the device's electron
