In this paper, a 64 mm×64 mm matrix polymer solar cell (PSC) was fabricated by air-brush spray deposition. Although the open-circuit voltage (Voc) and the fill factor (FF) both need to be improved, the efficiency of matrix PSCs still reaches about 1.82%, and especially the current density achieves nearly 20 mA/cm2. The results verify that air-brush spray deposition is a suitable method to prepare...
A new non-contact inspection technique based on laser-PSD (position sensitive detector) to inspect the inner surface of small-diameter pipe is proposed, and the corresponding sensor has been developed. After being reflected by two mirrors in series, a laser beam is projected onto the inner wall of a pipe as a small light spot and is read by a two-dimensional PSD. Based on the signals from the PSD...
