Perovskite solar cells free of hole transport layer

open access: yesJournal of Sol-Gel Science and Technology, 2019
In this work, easy and simple structured perovskite solar cells (PSCs) are designed and characterized. Our effort was to reduce the cost of the fabrication of such PSC devices, first by using an inexpensive starting precursor (aqueous methylamine solution) for the perovskite materials and second by design in a PSC structure free of the expensive hole ...

Harnessing Fungal Biowelding for Constructing Mycelium‐Engineered Materials

open access: yesAdvanced Engineering Materials, EarlyView.
Mycelium‐bound composites (MBCs) offer low‐carbon alternatives for construction, yet interfacial bonding remains a critical challenge. This review examines fungal biowelding as a biocompatible adhesive, elucidating mycelium‐mediated interfacial mechanisms and their role in material assembly. Strategies to optimize biowelding are discussed, highlighting

Investigating the performance of Tin-based perovskite solar cell with Cadmium Sulphide as etm and graphene as htm using SCAPS-1D

open access: yesФізика і хімія твердого тіла
Solar cells based on lead-free perovskite have demonstrated great potential for renewable energy. The SCAPS-1D simulation software was used in this study to perform device modelling of a lead-free perovskite solar cell of the architecture Glass/FTO/CdS ...

Interactions between Molten High‐Silicon Electrical Steels and Carbon‐Bonded MgO Refractories Based on Recyclates

open access: yesAdvanced Engineering Materials, EarlyView.
This study examines how several molten high‐silicon electrical steels interact with both conventional and recycled MgO–C refractories. For this, various immersion experiments are conducted. In addition to infiltration, a number of mechanisms are identified and explained that control the corrosion of the refractory material.

Half Metallic Bilayer Graphene [PDF]

open access: yes, 2013
Charge neutral bilayer graphene has a gapped ground state as transport experiments demonstrate. One of the plausible such ground states is layered antiferromagnetic spin density wave (LAF) state, where the spins in top and bottom layers have same ...

Reduction of Oxide Inclusions During the High‐Frequency Welding of Steel via a Nonthermal Ar/H2 Plasma Jet

open access: yesAdvanced Engineering Materials, EarlyView.
High‐frequency (HF) welding of steel is limited by oxide inclusions that degrade weld quality. This study demonstrates, for the first time, the integration of a nonthermal Ar/H2 dielectric barrier discharge (DBD) plasma jet into HF welding. Local plasma treatment provides effective shielding and in‐situ oxide reduction, resulting in markedly fewer and ...

An investigation into the optimal device design for selenium solar cells

open access: yesEnergy Reports, 2022
Despite a resurgence in recent years, the optimal device design for selenium solar cells is still not known with individual studies using significantly different window layers, hole transport layers and selenium absorber thicknesses.

Theory of carrier transport in bilayer graphene [PDF]

open access: yes, 2009
We develop a theory for density, disorder, and temperature dependent electrical conductivity of bilayer graphene in the presence of long-range charged impurity scattering as well as an additional short-range disorder of independent origin, establishing ...
