perovskite solar cells

An international team has sought to use indium sulfide as an electron transport material in a perovskite solar cell. The result is a device with lower defect density and improved performance.

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 open-circuit voltage of 2.112 V, a short-circuit current of 6.5 mA cm-2, and a remarkable fill factor of 81.9%.

Chinese researchers have used Mortise-Tenon technology to connect the perovskite absorber with the hole transport layer in a perovskite solar cell. They say that this reduces non-radiative recombination, while improving the cell’s open-circuit voltage and fill factor.

Italian scientists have used a titanium oxide sponge to successfully prevent lead leakage in a semitransparent solar cell. The device has demonstrated comparable efficiency to semi-transparent perovskite devices and has an average visible transmittance (AVT) of 31.4%.

Futurasun, an Italian module manufacturer, has acquired Rome-based Solertix. It now aims to bring its perovskite-based solar cell technology closer to commercial production.

An international research team has crafted an innovative solar cell design. By employing a top absorber consisting of methylammonium lead iodide (MAPbI3), a lead-halide perovskite, and a bottom absorber composed of FA0.5MA0.5Pb0.5Sn0.5I3, a perovskite material, the cell maximizes light absorption across a broad spectrum.

Scientists from the US National Renewable Energy Laboratory (NREL) and the University of Louisville have developed a revolutionary solar cell using yttrium-doped tin oxide nanoparticles. The innovation improves charge extraction and overall cell performance.

NASA has discovered that perovskite solar cells tested in space exhibit less degradation than reference devices tested on Earth. The agency acknowledged that it is uncertain about the specific factors in the space environment that contributed to the superior performance of the perovskite absorber film.

Researchers at India’s National Institute of Technology (NIT) Silchar, Assam, have designed a formamidinium tin iodide (FASnI3) active layer-based perovskite solar cell. It could potentially achieve a power conversion efficiency of 31.57%, while also scoring well on other performance parameters.

Egyptian researchers have developed a novel hole transport layer (HTL) for inverted perovskite solar cells using silver thiocyanate instead of the commonly used PEDOT:PSS and copper thiocyanate. The new HTL material demonstrated exceptional efficiency and stability in the constructed cell.
