Perovskite

A review of indoor PV cell technologies by an international research team delves into recent progress, characterization, and design strategies used to develop highly efficient cells. The study presents 250 commercial and laboratory devices, as well as applications and performance reporting.

Scientists in the United States have fabricated an all-perovskite tandem solar cell that reportedly shows reduced interfacial energy loss in the cell’s top device. It was built with a hole transport layer based on a compound known as P3CT that was doped with lead iodide.

Developed by researchers in China, the inverted perovskite device purportedly achieves the smallest nonradiative recombination-induced open-circuit voltage loss reported to date. It uses a synergistic bimolecular interlayer to functionalize the perovskite interface.

Researchers in China have built for the first time an inverted perovskite solar cell relying on a high-entropy hybrid perovskite material. The result is a device with an improved open-circuit voltage and fill factor, due to reduced non-radiative recombinations and optimized interface.

Chinese in China have utilized two sulfone-based organic molecules known as diphenylsulfone (DPS) and 4,4′-dimethyldiphenylsulfone (DMPS) to passivate absorber defects in perovskite solar cells. The result is a device with a higher electron cloud density at the interface between the perovskite material and the passivation layer.

The Saudi research institute said its new four-terminal tandem device has achieved the highest efficiency ever reported for perovskite-based 4-T and triple-junction tandem solar cells to date. The key feature of the cell is the hole transport layer of the top perovskite cell, which was engineered with self-assembled monolayers.

An international research group has sought to build for the first time a perovskite solar cell with the help of ChatGPT. The experiment helped the scientists identify a series of materials for the cell composition and the results were cells with a higher power conversion efficiency compared to that of reference cells built without the material proposed by the large language model.

Oxford PV has announced a record-setting 26.9% efficiency for its perovskite tandem module at Intersolar Europe 2024, the continent’s largest solar and energy storage event.

Sticky Solar Power is taking orders for industrial-scale versions of its novel room-temperature cell interconnection system, which is reportedly well-suited for back-contact (xBC), perovskite, and heterojunction cell technologies.

Canon has announced a new functional material for perovskite thin film passivation that potentially improves durability of perovskite solar cells while enabling a mass-production process. The Japanese company aims to start commercial production of the material in 2025.
