Abstract Molecule design of organic semiconductors (OSCs) for eliminating photoresponse and maintaining high charge mobility concurrently is beneficial to realize intrinsically photostable high‐performance field‐effect transistors (OFETs), which has never been reported. Here, a novel semiconductor TFP‐TT‐TPA with centrosymmetric structure synthesized. Remarkably, OFETs show negligible under light intensity up 170.4 mW cm −2 (higher than sunlight intensity, about 138 ), ensures that the...

Industrial radio frequency (rf) power applications, such as plasma generation, require high-frequency rf over a wide dynamic range and across variable load impedances. It is desired in these applications to maintain high efficiency fast response. This paper introduces scalable amplifier (PA) architecture control approach suitable for applications. approach, which we refer Multi-Inverter Discrete Backoff (MIDB), losslessly combines the outputs of paralleled switched-mode PAs, modulates number...
Applications such as plasma generation require the and delivery of radio-frequency (rf) power into widely-varying loads while simultaneously demanding high accuracy speed in controlling output across a wide range levels. Attaining efficiency performance all operating conditions meeting these system requirements is challenging, especially at frequencies (10s MHz) levels (1000s Watts above). This paper evaluates different architectures that directly address challenges enable efficient...

We demonstrate a novel spectrum-splitting module for integration with laterally-arrayed multi-bandgap micro-scale solar cells. The high-efficiency, low-cost, and low-profile design potentially enables significant improvement on performance reduction of energy production costs.
Many industrial radio-frequency (rf) power applications are characterized by high levels, narrow frequency ranges, and the need to combine rf from multiple sources. In HF range (3–30 MHz) above, combiners based on coupled transmission lines attractive due their small form factor efficiency. However, most available literature combining with transmission-line structures focuses response, little consideration regarding losses or efficiency optimization. This paper explores design optimization...
Wireless power transfer system in commercial electronic devices often employ duty cycle control for enhanced load regulation capabilities. When the transmitter operates deep mode, e.g. under light conditions, receivers based on synchronous rectifiers can exhibit significant voltage ringings ac nodes. For receiver-side in-band communication demodulation (e.g. frequency-shift keying as regulated WPC Qi standards), these transient be particularly concerning they cause data decoding errors,...
a Industrial radio-frequency (RF) power applications often require high-performance combiner network to efficiently merge from multiple amplifiers (PAs) and deliver it the load, at single operating frequency or within narrow band. Key requirements for such include small size, high efficiency, minimal reactive loading effects due parasitics. While combiners based on coupled transmission lines offer advantages in terms of size existing literature primarily focuses achieving broad response...
