SnO2 : A Wonderful Electron Transport Layer for Perovskite Solar Cells.

Small, 2018
The highest power conversion efficiency of perovskite solar cells is beyond 22%. Charge transport layers are found to be critical for device performance and stability. A traditional electron transport layer (ETL), such as TiO2 , is not very efficient for

Over 30% External Quantum Efficiency Light‐Emitting Diodes by Engineering Quantum Dot‐Assisted Energy Level Match for Hole Transport Layer

Advanced Functional Materials, 2019
In the study of hybrid quantum dot light‐emitting diodes (QLEDs), even for state‐of‐the‐art achievement, there still exists a long‐standing charge balance problem, i.e., sufficient electron injection versus inefficient hole injection due to the large ...

Transport layer fairness revisited

2015 13th International Conference on Telecommunications (ConTEL), 2015
Fairness amongst the competing flows at the transport layer has always been an important topic, however, the current definition based on the TCP-compatible view is not always suitable. With the increasing deployment of multipath transport protocols such as Multipath TCP (MPTCP) and the Concurrent Multipath Transfer extension of SCTP (CMT-SCTP), the ...

Efficient BiVO4 Photoanode with an Excellent Hole Transport Layer of CuSCN for Solar Water Oxidation

Advanced Energy Materials
Bismuth vanadate (BiVO4) is reported as a key material in photoelectrocatalysis owing to high theoretical efficiency, relatively narrow band gap of 2.4 eV, and favorable conduction band edge position for hydrogen evolution.

Transport Layer — Layer 4

1988
Open image in new window The Transport Layer is the highest layer in the OSI model which is directly involved with data communications. The network service provides routeing and relaying across real subnetworks, possibly involving the use of intermediate open systems; the transport service, in contrast, is concerned only with communication between end
