Design of B,N Co‐Doped Carbon Spheres for Highly Effective Back Interface Engineering in Planar Carbon‐Based Perovskite Solar Cells

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The energy level mismatch of the perovskite/carbon back interface is decreased remarkably by using B, N co‐doped carbon sphere electrode in C‐PSCs, leading to effective charge carrier separation, extraction, and transport at the back interface. Combined with further buried modification using AMPA, the power conversion efficiency of the C‐PSCs is up to ...

Modification of mesoporous silicas

open access: yes, 2000
Mesoporous silicas were post-synthetically modified with organometallic complexes in order to produce well defined supported meal centres.The first part of this thesis describes the synthesis of mesoporous silicas MCM-41(A), MCM-41(B) and A1MCM-41 using surfactant templates, MESLC using liquid crystal templates and KMES from an aged gel mixture.
