Stabilized Intermediate Phase Via Pseudo‐Halide Anions Toward Highly Efficient and Light‐Soaking Stable Perovskite Solar Cells

Advanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
The formate pseudo‐halide anion is strategically introduced at the buried interface to stabilize the intermediate phases formed during perovskite crystallization. The controlled crystallization enhances crystallinity and alleviates tensile strain, eliminating residual PbI2 near the buried interface.

Removing Homocoupling Defects in Alkoxy/Alkyl‐PBTTT Enhances Polymer:Fullerene Co‐Crystal Formation and Stability

Advanced Functional Materials, EarlyView.
PBTTT‐OR‐R, a C14‐alkoxy/alkyl‐PBTTT polymer derivative, is of substantial interest for optoelectronics due to its specific fullerene intercalation behavior and enhanced charge‐transfer absorption. Comparing this polymer with (S) and without (O) homocoupling defects reveals that PBTTT‐OR‐R(O) forms stable co‐crystals with PC61BM, while PBTTT‐OR‐R(S ...

Photo‐Assisted Zn‐Iodine Battery via Bifunctional Cathode with Iodine Host and Solar Response Boost

Advanced Functional Materials, EarlyView.
A bifunctional cathode based on BiOI materials is developed for photo‐assisted Zn‐iodine batteries, serving as both an iodine host and a solar‐responsive material. This design enables dual reaction routes involving vacancy‐based iodine storage and reversible two steps iodine redox.

Wind power in Denmark! Wind power in Sweden?

Journal of Wind Engineering and Industrial Aerodynamics, 1988
Abstract It is now fifteen years since the oil crisis started the hunt for “new” energy sources. In Denmark and Sweden modern national wind energy programmes started around 1975 to investigate the possibilities for using wind power and eventually erect windmills.

WIND POWER

1986
Publisher Summary This chapter describes the wind power technology and applications. Medium sized wind turbines have to be used in connection with a large electrical grid. These machines have a turbine diameter of 7–17 m and a power output of 10–75 kW. Wind energy can only be economical in areas of good wind availability.

Working with wind - wind power

Engineering & Technology, 2008
The increased availability of wind power is beginning to cause utilities problems as engineers attempt to synchronise the power grid. Utilities have tended to ignore the operational aspects of wind power until there are commercial pressures to take positive action.
