Dynamic ON-resistance (RON) in GaN HEMTs is a critical issue for power electronics efficiency. This paper proposes a novel method to measure dynamic (RON) under long-term OFF-state drain-stress and steady-state soft-switching, comparing Schottky-type (GaN- ...

Zinc phosphide (Zn3P2) has been lauded as a promising solar absorber material due to its functional properties and the abundance of zinc and phosphorous. In the last 4 decades, there has not been any significant improvement in the efficiencies of Zn3P2-bas ...

Perovskite solar cells have led the new surge of solar energy research. However, their instability is a pressing issue mostly attributed to the perovskite interface with charge-selective transport layers. In this work, diethylammonium iodide (DEAI) surface ...

The origin of the low densities of electrically active defects in Pb halide perovskite (HaP), a crucial factor for their use in photovoltaics, light emission, and radiation detection, remains a matter of discussion, in part because of the difficulty in det ...

Chiral cyclooctadienes are a frequently occurring scaffold in natural products and specialty chemicals, and are used as ligands in asymmetric catalysis. Accessing substituted cyclooctadienes in an efficient asymmetric fashion has been notoriously challengi ...

In this paper, some practical issues related to the manufacturing, and design criteria related to the application in devices of a hybrid silver grid/poly (3,4-ethylenedioxythiophene) semi-transparent electrode are discussed. The electrodes are fabricated b ...

Today more than 90% of the global PV market is covered by c-Si solar cells which are limited by recombination losses at the metal-semiconductor interface. This recombination path can be avoided by separating the metal from the c-Si wafer by introducing a b ...

We present a mathematical model to predict the effect of potential-induced degradation (PID) on the power output of c-Si modules in different climates. For the experimental part, we manufacture mini-modules made of two c-Si p-type cells, and use accelerate ...

Heterocycles are important compounds in organic chemistry. To introduce functional groups on heterocycles or synthesize functionalized heterocycles stays a hot topic of research. Among all the functional groups, alkynes attracted a lot of attention not onl ...

Thin-film hydrogenated amorphous silicon solar (a-Si:H) cells are known to have better temperature coefficients than crystalline silicon cells. To investigate whether a-Si:H cells that are optimized for standard conditions (STC) also have the highest energ ...

A mere 2 nm conformal titanium dioxide overlayer coated by atomic layer deposition is shown to act as a blocking layer for high-efficiency solid-state perovskite (CH3NH3PbI3) absorber-based solar cells. Surpassing the existing multilayer passivation, this ...

This research studies the optical and electronics properties of Solid-State Dye-Sensitized Solar cells (SSDSCs). The propagation of light inside dye anchored TiO2 mesoporous layer includes scattering and absorption of photons. The light absorption behavior ...
