Abstract In a microscopic model of the photoelectric effect, it becomes clear that conservation energy is exclusively determined by Doppler shift processes, i.e. , whole photon vanishes means redshifts. Accordingly, if generated, won blueshifts. This supposed to be valid for all processes with conservation. An experiment carried out make this flow visible interactions probes. The result weak fo...

A silicon nanocrystals (Si-ncs) conjugated-polymer-based bulk-heterojunction represents a promising approach for low-cost hybrid solar cells. In this contribution, the bulk-heterojunction is based on Si-ncs prepared by electrochemical etching and poly(3-hexylthiophene) (P3HT) polymer. Photoelectric properties in parallel and vertical device-like configuration were investigated. Electronic inter...

Perovskite solar cells have emerged as promising photovoltaic systems with superb power conversion efficiency. For the practical application of perovskite devices, the greatest concerns are the power output density and the related dynamics under working conditions. In this study, the working conditions of planar and mesoscopic perovskite solar cells are simulated and the power output density ev...

In today’s rapid development of multiphase organic photodetectors(OPDs), research on inverted ternary OPDs is very necessary. Therefore, this paper innovatively proposes an photodetector(OPD) with a structure ITO/PEIE/PC $$_{61}$$ BM/P3HT: PCPDTBT/MoO $$_{3}$$ /Al. And the PEIE electron transport layer(ETL), which essential for structure, used to study effects different thicknesses. Different t...

In this paper, the fabrication and characterisation of pentacene-based photoconductors using indium tin oxide electrodes obtained by ion beam sputtering are discussed. The photoelectric properties of pentacene under red (632 nm) and ultraviolet (365 nm) illuminations were investigated. We have shown that the photocurrent was dependent on the wavelength, bias voltage and illumination side of the...

A phoswich detector with two scintillation layers has been designed and assembled at Oregon State University. This detector is able to identify and reject Compton events and ultimately reduce the Compton continuum in gamma energy spectra. In this detector, CsI(Tl) crystal is used to primarily detect photoelectric events. The CsI(Tl) crystal is partially surrounded by a BGO crystal layer to capt...

FPGA can solve the lack of custom circuit, and overcome the original programmable gate device limited number of faults. The paper presents application of FPGA in high-speed CMOS digital image acquisition and color recognition system. Color recognition system is mainly composed of analog and digital two parts. The analog part mainly used photoelectric signal conversion, amplification and filteri...
