Perovskite

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.

US scientists have analyzed the impact of “seasoning” a formamidinium lead iodide solution with two-dimensional (2D) perovskites. They have found that the template improved the efficiency and durability of their solar cells.

Swift Solar, a specialist in perovskite tandem photovoltaics, plans to build a factory in the U.S. in the next two to three years to manufacture thin-film solar.

China’s Utmo Light showcased its first full perovskite PV module at this week’s SNEC PV trade fair in Shanghai, underscoring the technology’s ongoing shift toward commercialization.

The result is the best efficiency ever recorded for a carbon-based PV cell using unconventional hole transporting materials to date. The device was built with a hole transparent layer based on electrochemically produced large-area phosphorene flakes, which reportedly enable the required band energy alignment within the cell.
