Optimised Heat Pump Management for Increasing Photovoltaic Penetration into the Electricity Grid
(2019)Advanced control of heat pumps with thermal storage and photovoltaics has recently been promoted as a promising solution to help decarbonise the residential sector. Heat pumps and thermal storage offer a valuable flexibilisation ... -
Optimization of thin-film highly-compliant elastomer sensors for contractility measurement of muscle cells
(2016)Test assays capable of providing quantitative characterization of the contraction of cardiac and smooth muscle cells are of great need for drug development and screening. Several methodologies have been proposed for achieving ... -
Optimization of tunnel junction IBC solar cells based on a series resistance model
(2019)This work presents the upscaling of the tunnel IBC technology on large area, Czochralski (Cz) n-type wafers. At the junction level, a self-aligned PECVD masking technology has been developed for the deposition of hydrogenated ... -
Optimizing the Consumption of Spiking Neural Networks with Activity Regularization
(2022-05)Reducing energy consumption is a critical point for neural network models running on edge devices. In this regard, reducing the number of multiply-accumulate (MAC) operations of Deep Neural Networks (DNNs) running on edge ... -
Organic–inorganic halide perovskite/crystalline silicon four-terminal tandem solar cells
(2014)Tandem solar cells constructed from a crystalline silicon (c-Si) bottom cell and a low-cost top cell offer a promising way to ensure long-term price reductions of photovoltaic modules. We present a four-terminal tandem ... -

Parasitic Absorption Reduction in Metal Oxide-Based Transparent Electrodes: Application in Perovskite Solar Cells
(2016)Transition metal oxides (TMOs) are commonly used in a wide spectrum of device applications, thanks to their interesting electronic, photochromic, and electrochromic properties. Their environmental sensitivity, exploited ... -
Passivating electron contact based on highly crystalline nanostructured silicon oxide layers for silicon solar cells
(2016)We present a novel passivating contact structure based on a nanostructured silicon-based layer. Traditional poly-Si junctions feature excellent junction characteristics but their optical absorption induces current losses ... -
Passive mode-locking in the cavity of monolithic GaN-based multi-section laser diodes
(2013-03-04)We demonstrate picosecond pulse generation in the blue-violet wavelength region by passive intra-cavity mode-locking in GaN-based ridge waveguide laser diodes with monolithically integrated absorbers. For cavity lengths ...
