FPT University is my dream school. After entering the school I was placed in the trans class even though my English is not really good. After 2 months of taking trans 4 class, I have had a lot of interesting experiences. I was taught by 2 very enthusiastic teachers, Mr. Roy Gocela from the Philippin...

YMXene-Assisted Perovskite Solar Cells
MXene-Assisted Perovskite Solar Cells Rnx8V
A large and rapidly expanding class of two-dimensional (2D) metal carbides,
nitrides, and carbonitrides called MXenes, with their interesting photovoltaic
applications and tunable surface termination, has found a vast range of applications
as improving the perovskite solar cells (PSCs) performance. By doing simulations,
we report the influence of additive Ti3C2Tx MXene into the absorber layer, and at
the interfaces in a PSC, to achieve physical understandings about its impact on the
improvement of PSC performance. In this work, the considered architecture
contains the methylammonium lead triiodide (MAPbI3) absorber layer, TiO2
electron transport layer, and Spiro-OMeTAD hole transport layer. The simulations
show that the addition of Ti3C2Tx to halide perovskite and TiO2 layers induces electric dipole at the interfaces that can change the band alignment between the
charge transfer layers and absorber layer. The combined action of work function
tuning and interface engineering can modify electric field distribution in the layers
that can increase built-in potential, affect the photocurrent and current density, and
finally, improve the performance in MXene-modified PSCs with respect to
reference cells without MXene. This work provides a theoretical discussion to
display the promising role of MXenes to be used in PSCs to improve their
performances.

An army of people claim that it is better to allow people to choose the styles of their houses instead of old styles of housing. Although there might be some disadvantage over th...
