“…The effect of both the Cu grid and the patterned OPD design on the optical transmittance and its design optimization are discussed below. Electro-optical simulations and design rules for NIR OPDs with a printed Cu grid TCE The effect of the metal grid design on the performance of organic photovoltaics was studied experimentally [16][17][19][20][21] and simulated [39][40][41] .

Touchless technology based on user interaction modes such as voice or gestures is paving the way for tomorrow’s digital ecosystems, accelerated by hygiene requirements resulting from the COVID-19 pandemic. Gesture-based touchless user interfaces typically use near-infrared (NIR) cameras. The applicability of these systems is hampered by their limitations in field of view and their calibration requirements for high accuracy. Here, we show a novel touchless user interface based on a large-area visually transparent NIR-sensitive 16 × 16 organic photodetector (OPD) array that can be used on top of a display as a touchless user interface. Optical transparency is realized by implementing a printed copper (Cu) grid as a bottom transparent conductive electrode (TCE) and an array of patterned OPD subpixels. Electro-optical modelling enabled an optimal image sensor design that resulted in a high photodetectivity of ca. 1012 Jones at 850 nm and high visible-light transmittance of 70%. We demonstrate that our imager can be used as a penlight- and gesture controlled touchless user interface when combined with a commercial display.

Optimization complications are solved using meta-heuristic methods, which transforms the complex data into simplest way and computational process is quite attractive because of their intensification, diversification, and accurate evaluating/computational behavior on the nonlinear data. Among different existing meta-heuristic algorithms, Tabu Search Optimization (TSO) algorithms have robust performance due to escaping strategy from local optimum and extensive extraction ability. Hence, this paper delineates the TSO searching technique for extracting the parasitic parameters of solar Photovoltaic (PV) modules under different climatic stipulations. Double diode design is developed and implemented in the operational aspect based on the extraction issue. The six parameters of the solar cell, i.e., I Ph , I 01 , I 02 , R S , R P , a 1 are emulated and the obtained data is investigated using TSO approach, at the same time the extracted data is compared with the effective selected metaheuristic algorithms such as Gravitational Search Algorithm (GSA), Lightning Search Algorithm (LSA), Pattern Search (PS), Particle Swarm Optimization (PSO) and Genetic Algorithm (GA). Compared to the existing algorithms, TSO has very less computational time to extract all the six parameters.
