perovskite solar cells

The researchers of the Belgian research institute used a dual-layer treatment for the perovskite absorber, which they said improved the cell efficiency and stability. The device achieved an open-circuit voltage of 1.17 V, short-circuit density of 24.5 mA/cm2, and a fill factor of 84.6%.

The National Renewable Energy Laboratory (NREL) has made highly bifacial perovskite cells with a front-side efficiency of 23%.

German scientists have fabricated a carbon electrode perovskite solar cell with a hole-transporting bilayer made of organic semiconductors instead of a conventional hole transport layer. They claim this approach improves the device’s fill factor and open-circuit voltage.

European scientists used a nanosecond pulsed ultraviolet laser to reduce surface defects in perovskite films for solar cell applications. The result is a significant increase in cell efficiency and stability. The new technique may be particularly suitable for roll-to-roll (R2R) production lines.

GCL-SI has launched a new 320 W perovskite solar module. The company guarantees that the 10-year end power output will be at least 90% of the nominal output power, which decreases to 80% after 25 years.

Qatari researchers have incorporated an electron transport layer (ETL) made of tin(IV) oxide into a perovskite solar cell through air-thermal-annealing, resulting in better efficiency and stability. The device demonstrated an open-circuit voltage of 1.045 V, a short-circuit current of 22.01 mA/cm2, and a fill factor of 74.3%.

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%.
