Solution-processed polymer optoelectronic devices such as light-emitting diodes and solar cells have many advantages for large-area manufacture, and show increasing levels of performance. Here, we review recent progress in using blends of two conjugated polymers for optoelectronic devices. The blending of two or more polymers allows tuning of device performance, and for photovoltaics presents a...

Integrated circuits and optoelectronics are currently dominated by silicon technology. However, silicon’s response wavelength is typically less than 1,100 nm, limiting the application of in machine vision, autonomous vehicles, night vision. For infrared photodetectors, HgTe colloidal quantum dots (CQDs) promising materials. Because adjustable bandgap, it responds over a wide spectral range. con...

Electromagnetic radiation can be described as a stream of individual photons. In solid-state detectors (e.g., photocathodes or semiconductor photosensors), each photon of sufficient energy creates one or several mobile charge carriers which can be subsequently detected with sensitive electronic circuits, possibly after charge packet multiplication employing the avalanche effect. Two types of no...

Abstract Since Complementary metal–oxide–semiconductor technology is the conventional for micro- and optoelectronics, integration of emerging materials, such as halide perovskites, into process an important branch perovskite technologies development. In this regard ITO free device research becomes increasingly important. The Perovskite Light-Emitting electrochemical cells are a promising altern...
