Photovoltaics : reviewing the European feed-in-tariffs and changing PV efficiencies and costs [PDF]

, 2014
Feed-in-Tariff (FiT) mechanisms have been important in boosting renewable energy, by providing a long-term guaranteed subsidy of the kWh-price, thus mitigating investment risks and enhancing the contribution of sustainable electricity.

Colossal Photovoltaic Current in Ferroelectric Oxide by Constructing Defect Band

Advanced Science, EarlyView.
Colossal photovoltaic current density of 34.36 mA/cm2 under 375 nm illumination has been achieved in the Pb‐deficient PbTiO3 film. The ultraviolet photoresponsivity surpasses that of all reported ferroelectric materials. This enhancement is attributed to the junction effect between the Pb‐deficient and non‐defective layers.

Integrated Photoelectrode and Electrolyte Engineering via Carbon Quantum Dots for Self‐Powered H2O/O2‐Mediated Portable Photoelectrochemical Cells

Advanced Science, EarlyView.
Surface‐charged N‐CQDs serve as both electrolyte additives and photocathode modifiers. Electrodeposited N‐CQDs on Cu2O form a stable composite, steering 4e− ORR toward water. A quasi‐solid electrolyte with N‐CQDs aids charge migration, electrode‐electrolyte interfacial compatibility and replenishes active sites.

Alcohol‐Adduct Mediated Precursor Stabilization Strategies for Conformal SnO2 Layers in Highly Efficient and Stable Perovskite Solar Modules

Advanced Energy Materials, EarlyView.
An alcohol‐adduct‐mediated strategy is employed to stabilize tin isopropoxide for the formation of a homogeneous double electron transport layer (ETL) incorporating SnO2 nanoparticles (NPs). This double‐ETL exhibits improved optical and charge‐transport properties due to reduced defect density and better energy level alignment, resulting in high ...

Vapor‐Phase Grain‐Boundary Anchoring Enables Molecular Toughening and Record Bending Endurance in Pilot‐Scale Roll‐to‐Roll‐Printed Flexible Perovskite Modules

Angewandte Chemie, EarlyView.
A vapor‐phase molecular toughening strategy is developed for pilot‐scale roll‐to‐roll (R2R) ‐compatible fabrication of flexible perovskite solar modules. Thiol vapor selectively regulates crystallization and anchors at grain boundaries, reducing defects while enhancing mechanical resilience.
