We report different solar cell designs which allow a simple electrical connection of subsequent devices deposited on the same substrate. By arranging so-called standard and inverted solar-cell architectures next to each other, a serial connection of

This work reports a reversible braking system for micromotors that can be controlled by small temperature changes (≈5 °C). To achieve this, gated‐mesoporous organosilica microparticles are internally loaded with metal catalysts (to form the moto

It is common knowledge that molecular energy level offsets of a type II heterojunction formed at the donor–acceptor interface are considered to be the driving force for photoinduced charge transfer in organic solar cells. Usually, these offsets –

A new sidechain-based statistical anthracene-containing poly(arylene-ethynylene)-alt-poly(p-phenylene-vinylene) (P2) bearing 2-ethylhexyloxy and decyloxy side chains was synthesized to study the effect of elongating the sidechain length from octyloxy

The bulk heterojunction morphology of organic solar cells widely controls their device efficiency and stability. Structural order and domain size of the donor phase strongly impact the charge separation efficiency, recombination rates, and the hole p

Lately, non-fullerene acceptors (NFAs) have received increasing attention for use in polymer-based bulk-heterojunction (BHJ) organic solar cells (OSCs), as improved photovoltaic performance compared to classical polymer–fullerene blends could be de
