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 ... -
Pathways to electrochemical solar-hydrogen technologies
(2018)Solar-powered electrochemical production of hydrogen through water electrolysis is an active and important research endeavor. However, technologies and roadmaps for implementation of this process do not exist. In this ... -
Patterning solar cell metal grids on transparent conductive oxides using self-assembled phosphonic acid monolayers
(2019-12-01)We present a novel, simple and cost-effective method for patterning transparent conductive oxides (TCO) in order to form solar cell's metal grid by electro-plating. Self-assembled monolayers (SAMs) are prepared by dipping ... -
Performance Assessment of a Dedicated Reflectance Pulse Oximeter in a Neonatal Intensive Care Unit
(2018)The measurement of peripheral oxygen saturation (SpO2) in neonatal intensive care units (NICUs) poses a significant challenge. Motion artifacts due to the patient’s limb motion induce many false alarms, which in turn cause ... -

Perovskite/Perovskite/Silicon Monolithic Triple-Junction Solar Cells with a Fully Textured Design
(2018)High efficiency triple-junction solar cells are currently made of III-IV semiconductors using expensive deposition methods. Perovskite/perovskite/silicon monolithic triple-junction solar cells could be a lower-cost alternative ... -
Perovskite/Silicon Tandem Solar Cells: Challenges Towards HighEfficiency in 4-Terminal and Monolithic Devices
(2017)Perovskite and silicon solar cells have recently been shown to be perfect partners for tandem devices with potentially very high efficiency at low additional costs over standard silicon cells. Here, we present the development ... -
Perovskite/Silicon Tandem Solar Cells: Marriage of Convenience or True Love Story? - An Overview
(2018)Perovskite/silicon tandem solar cells have reached efficiencies above 25% in just about three years of development, mostly driven by the rapid progress made in the perovskite solar cell research field. This review aims to ... -

Phosphorous-Doped Silicon Carbide as Front-Side Full-Area Passivating Contact for Double-Side Contacted c-Si Solar Cells
(2019)We present an electron selective passivating contact based on a tunneling SiO. capped with a phosphorous doped silicon carbide and prepared with a high-temperature thermal anneal. We investigate in detail the effects of ... -
Photo-acoustic dual-frequency comb spectroscopy
(2020-08-20)Photo-acoustic spectroscopy (PAS) is one of the most sensitive non-destructive analysis techniques for gases, fluids and solids. It can operate background-free at any wavelength and is applicable to microscopic and even ... -
Photonic chip based optical frequency comb using soliton induced Cherenkov radiation
(2015)Microresonator optical frequency combs have become an actively researched alternative way to generate optical frequency combs. Their key properties are large mode spacings and the potential for photonic integration which ... -
Photoplethysmography-Based Ambulatory Heartbeat Monitoring Embedded into a Dedicated Bracelet
(2013-09-22)Ambulatory electrocardiogram (ECG) monitors have been intensely used since half century but are still associated to clinical/ambulatory cumbersome procedures. The question of this research is the following: what is the ...
