and the improved quality of the bottom of the perovskite films featuring a larger grain size with low defects, together promote the more efficient charge transfer and the suppressed non-radiative ...

A Chinese research team has fabricated an all-perovskite solar cell with a 3D/3D double-layer perovskite heterostructure that reportedly ensures improved charge extraction. The device achieved an ...

Tsukuba, Japan—Perovskite solar cells are attracting ... in one-dimensional overlapping manner and thereby facilitates charge transfer. Despite demonstrating high charge mobility, perovskite ...

Professor Lee said, "Through this study, we have effectively solved the charge accumulation and energy band mismatch problems ...

"The MoS 2 interlayer increases the surface contact area with the adjacent perovskite layer, improving charge transfer dynamics between the two layers," wrote Koo, Choi and their colleagues.

Most traditional optoelectronic devices in use today exploit control of charge and light ... chiral molecule to transfer its properties without changing the perovskite composition makes the ...
