Efficient planar heterojunction perovskite solar cells by vapour deposition
Many different photovoltaic technologies are being developed for large-scale solar energy conversion. The wafer-based first-generation photovoltaic devices have been followed by thin-film solid… Expand
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… Expand

The organic-inorganic hybrid perovskites methylammonium lead iodide (CH3NH3PbI3) and the partially chlorine-substituted mixed halide CH3NH3PbI3-xClx emit strong and broad photoluminescence (PL)… Expand
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… Expand
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… Expand
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… Expand
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… Expand
Improving and Stabilizing Perovskite Solar Cells with Incorporation of Graphene in the Spiro-OMeTAD Layer: Suppressed Li Ions Migration and Improved Charge Extraction
Perovskite solar cells (PSCs) have achieved a huge success in power conversion efficiency (PCE), although they still suffer from the long-term stability problem caused by the intrinsic sensitivity ...
Anti-solvent free fabrication of FA-Based perovskite at low temperature towards to high performance flexible perovskite solar cells
Abstract Flexible solar cells have attracted increasingly attentions due to its possible extensive applications in wearable, portable, flyable and deployable devices. The fabrication of flexible… Expand
