The endeavour towards making power distribution systems (PDSs) smarter has made the interdependence on communication network indispensable. Further, prospective high penetration of intermittent renewable energy sources in the form of distributed energy resources (DERs) has resulted in the necessity for smart controllers on such DERs. Inverters...

The most simple grid connected PV system consists of a series connection of PV modules, connected to a string inverter. The power output of such a system can be sensitive to shade on a PV module. Also limited shade on a part of a cell can lead to high temperatures in that shaded cell, a so-called hotspot. The effect of shade can be reduced by...

Large scale implementation of PV in urban areas asks for more shadow tolerant modules and more size flexibility. Power optimizers and micro inverters can be used to improve shadow tolerance of standard c-Si modules but the electrical interconnection and the size of cell groups in the standard module design is a limiting factor when it comes to...

Split-gate ambipolar organic transistor technology is gaining interests as a practical solution for the implementation of complementary transistors. It is known that conventional ambipolar transistors suffer from poor DC gain, noise margin, and high power consumption, as they do not have a well-defined off-state region. A split-gate device...

A study of the photonic flash sintering of a silver nanoparticle ink printed as the back electrode for organic solar cells is presented. A number of sintering settings with different intensities and pulse durations have been tested on both full-area and grid-based silver electrodes, using the complete emission spectrum of the flash lamps from UV...

Building integrated and building attached photovoltaic (BIPV, BAPV) systems may suffer from lower performance than predicted as a result of unwanted partial shading. New system architectures have been proposed to optimize performance. The common approach of these new architectures is to track the maximum power point of every solar module...

All-solution processed organic solar cells with inverted device architecture were demonstrated. Devices contain opaque bottom electrodes and semitransparent top electrodes, resulting in top illuminated devices. Nanoparticles-based Ag ink was used for inkjet printing both top and bottom electrodes. Semi-transparent top electrode consists of high...

A wide range of characterization techniques are used to study spin-coated films of zinc oxide (ZnO) obtained from thermal decomposition of zinc acetylacetonate hydrate. Inverted organic solar cells with ZnO transport layers were prepared. Deposition conditions of the solution onto the substrate (e.g. substrate temperature) were found to be...

Solution processing of the electrodes is a big challenge towards scaling up and R2R processing of organic solar cells. Inkjet printing is a non-contact printing method, it can be realized by solution processing at ambient condition and provides freedom of shape in the electrode pattern. The inkjet and screen printing of the back electrode in...

In this work, we realize complementary circuits with organic p-type and n-type transistor integrated on polyethylene naphthalate (PEN) foil. We employ evaporated p-type and n-type organic semiconductors spaced side by side in bottom-contact bottom-gate coplanar structures with channel lengths of 5 μm. The area density is 0.08 mm2 per...

Within this work we present n-type self-assembled monolayer field-effect transistors (SAMFETs) based on a novel perylene bisimide. The molecule spontaneously forms a covalently fixed monolayer on top of an aluminium oxide dielectric via a phosphonic acid anchor group. Detailed studies revealed an amorphous, two-dimensional semiconducting sheet...

This work describes n-type self-assembled monolayer field-effect transistors (SAMFETs) based on a perylene derivative which is covalently fixed to an aluminum oxide dielectric via a phosphonic acid linker. N-type SAMFETs spontaneously formed by a single layer of active molecules are demonstrated for transistor channel length up to 100 μm. Highly...

This paper proposes the use of a three-phase four-leg (3P4L) converter in combination with an LCL filter for the inverter stage of a solid state transformer (SST). This configuration gives full control over the line-to-line, as well as the line-to-neutral voltage and currents, while providing exceptional harmonics mitigation. A procedure to...

Dual-gate organic transistor technology is used to increase the robustness of digital circuits as illustrated by higher inverter gains and noise margins. The additional gate in the technology functions as a VT-control gate. Both zero-VGS-load and diode-load logic are investigated. The noise margin of zero- VGS-load inverter increases from 1.15 V...

Inverted polymer:fullerene solar cells with ZnO and MoO3 transport layers are demonstrated. ZnO films are prepared through spin casting of a zinc acetylacetonate hydrate solution, followed by low temperature annealing under ambient conditions. The performance of solar cells with an inverted structure is shown to be equivalent to that of...
