The TRMC technique is commonly employed to examine the dynamics of photogenerated charge carriers in semiconductor materials characterized by low background conductivities. TRMC relies on the interaction between the mobile charge carriers and the electric field component of the microwaves, allowing for the...
Commercialization is widely believed to be achievable for metal halide perovskite solar cells with high efficiency and low fabrication cost. However, stability remains a key obstacle for them to compete with established photovoltaic technologies. The pho

Zhijun Ning is an assistant professor at the School of Physical Science and Technology, ShanghaiTech University, ...
In addition to the above-mentioned perovskite-based tandem solar cells, there have been other approaches to perovskite-tandem cells employing emerging photovoltaic materials. These include combinations such as perovskite/CZTSSe, perovskite/colloidal quantum dots (QDs), and perovskite/CdTe. The application...
Due to their outstanding optoelectronic properties, lead-based halide perovskite materials have been applied as efficient photoactive materials in solution-processed solar cells. Current record efficiencies offer the promise to surpass those of silicon s
Different 2D and quasi-2D perovskite materials have demonstrated significant improvements in the device stability compared to 3D perovskites due to their increased hydrophobicity and suppressed ion migration. However, fundamental investigations of these
What causes the instability of perovskite solar cells has been a puzzling problem impeding the development of commercial panels. So far there is limited evidence on the link between device instability and the various materials in each of the stacked laye

the presence of bulky organic cations in 2D structure hampers the charge transport, and as a result of this, the solar cell devices based on 2D perovskite materials have lower efficiencies compared with the pure three-dimensional (3D) perovskite-based solar cells12,14,15. Due to these reasons...
the use of 2D perovskite materials presents additional challenges in fabricating high-efficiency solar cells, as the crystal orientation in the photo-absorber film significantly affects the device performance. To overcome this, Tsai et al. developed a hot-casting spin-coating method for the preparation...
