Simulation Insights Into Enhanced Emitter Contact Passivation via LECO on Industrial TOPCon Solar Cells

Progress in Photovoltaics: Research and Applications, EarlyView.
Numerical simulations were employed to boost industrial TOPCon cells from 25.5% to 26.07% by suppressing J0e,metal,eff without compromising ρc with a dual optimization strategy: (1) engineering the selective emitter sheet resistance (Rsh_SE) to 117 Ω/□ and (2) reducing the LECO‐induced partial metal contact ratio (fpmc) to 1%.

Wet‐Transferred MoS2 on Passivated InP: A Van der Waals Heterostructure for Advanced Optoelectronic Applications

physica status solidi (RRL) – Rapid Research Letters, Volume 19, Issue 5, May 2025.
This study presents a photodetector based on atomically thin MoS2 on an InP substrate, forming an n‐MoS2/p‐InP type‐II staggered heterojunction. The device exhibits excellent rectifying properties with an ideality factor of 1.57 and achieves a peak photoresponsivity of 960 mA W−1, while MoS2 provides stable passivation for InP. III–V semiconductors are

Back bombardment for dispenser and lanthanum hexaboride cathodes

Physical Review Special Topics. Accelerators and Beams, 2011
The back bombardment (BB) effect limits wide usage of thermionic rf guns. The BB effect induces not only ramping-up of a cathode’s temperature and beam current, but also degradation of cavity voltage and beam energy during a macropulse.

The Role of Interfacial Energetics and Defects on The Efficiency of Tin Perovskite Solar Cells

Small, EarlyView.
ABSTRACT Tin perovskites are emerging as a sustainable alternative to lead‐based photovoltaics, yet their efficiency remains limited by energy‐level mismatch and intrinsic instability from tin oxidation. Progress is further hindered by inconsistent electrical behavior, obscuring the true bottlenecks of device performance.

Electrically Tunable Tunneling and Spectral Response in WSe2/h‐BN/CdSe/Graphene Heterostructure

Small, EarlyView.
In the WSe2/h‐BN/CdSe quantum dot/graphene heterostructure, the graphene voltage dynamically tunes the tunneling barrier and energy alignment across the h‐BN layer. The bias‐dependent Fermi‐level alignment enhances the tunneling density of states, leading to efficient extraction of photo‐excited electrons from QDs into WSe2 and graphene.

Effect of Intrinsic Carbon in Hot Briquetted Iron on Melting and Refining Efficiency under Electric Arc Furnace Conditions for Sustainable Steelmaking with Active Use of H2‐Reduced Iron

steel research international, EarlyView.
The melting behavior of hot briquetted iron (HBI) is observed and compared with FactSage computing simulation. When using HBI in an electric arc furnace process, a proper design of intrinsic carbon content in HBI, charging ratio of HBI, and addition of lime are proposed to be essential to control the slag volume, maintain slag basicity, and mitigate ...
