Perovskite

GIST researchers have developed a perovskite mini-module with 22.56% efficiency by improving the SnO₂ electron transport layer with PEI, reducing defects and electron loss. The module retained 94% of its performance after 500 hours, highlighting potential for scalable, stable perovskite solar cells and modules.

Shenzhen-based SolaEon has reported a 27.87% efficiency for a single-junction perovskite solar cell on a 0.076 cm² lab device, certified by China’s National Photovoltaic Industry Metrology and Testing Center.

A Chinese-Swedish research team has boosted the performance of tin-lead perovskite solar cells by modifying additives and post-treatment processes. The device also demonstrated improved stability, retaining 60% of its initial efficiency after 550 hours at 85 °C under maximum power point conditions.

Halocell Energy is set to benefit from the development of a sovereign supply chain for high-purity precursors to perovskite after signing a memorandum of understanding with Queensland advanced materials company Lava Blue.

Researchers from KAUST, TU Delft, and LMU Munich have improved the performance of monolithic perovskite-silicon tandem solar cells by modifying the physical structure at the front of the bottom heterojunction solar cell.

Researchers have used multivalent amidinium ligands to boost perovskite solar cell efficiency to 25.4%, achieving over 95% stability after 1,100 hours at 85  C. The proposed approach enables controlled low-dimensional passivation layers, offering a practical route for durable, large-area perovskite devices.

The Chinese perovskite solar technology developer said the result is currently under testing by an unspecified third-party authoritative laboratory in China. The achievement is part of the company’s efforts to bring its perovskite cell technology closer to commercial production.

The Chinese energy and oil company said the cell can be used as a top device in perovksite-silicon tandem configurations. The result was confirmed by the Shanghai Institute of Microsystem and Information Technology (SIMIT).

Researchers in China developed a monolithic perovskite-silicon tandem solar cell using a steric-complementary interface design, achieving a certified efficiency of 32.12% and enhanced long-term stability. This strategy optimizes molecular fit in the perovskite lattice, improving both charge transport and device longevity.
