A model is derived for the frequency and time domain optoelectronic response of perovskite solar cells (PSCs) that emphasizes the role of charge carrier exchange, i.e., extraction and injection, from (to) the perovskite through the transport layer to

Diffusion lengths are abundantly mentioned as a key enabler of high performance in lead-halide perovskite solar cells based on the implicit assumption that diffusion lengths are directly connected to efficient collection of charge carriers. While lon

This paper proposes a flexible digital control scheme for isolated phase-shift full-bridge (PSFB) converters. The required transformer suffers from inevitable imbalance of magnetic flux resulting in an increased magnetizing DC-offset current that thr

The power conversion efficiencies of most organic solar cells roll off quickly with thickness more than 100 nm. Here, Wu et al. show that avoiding excessive charge accumulation in the intra-bandgap tail states is vital to maintain the photocurrent ge
