Toshiba raises efficiency of transparent cuprous oxide solar cell from 8.4% to 9.5%

Toshiba has revealed that it has improved the power conversion efficiency of a transparent cuprous oxide solar cell to 9.5%, from the 8.4% mark it reached in December 2021. It enlarged the cell and suppressed carrier recombination at the edge of the cuprous oxide (Cu2O) generation layer, which usually causes generation efficiency degradation.

Toshiba expands fuel cell business

Toshiba is cooperating with Swedish battery specialist Echandia to develop pure hydrogen fuel cells that could be used for continuous operation in marine applications.

Toshiba launches 20Ah rechargeable lithium-ion battery

Toshiba has developed a battery that can be used with PV modules, with a design that charges and discharges at high currents. The new 20Ah-HP SCiB product has a rated capacity of 20Ah, a nominal voltage of 2.3V, and an input power of 1,900W. It measures 116 mm x 22 mm x 106 mm and weighs 545 grams.

Toshiba claims 8.4% efficiency for transparent cuprous oxide solar cell

The record efficiency was achieved by engineering the cell with reduced copper(II) oxide (CuO) and copper (Cu) impurities in the thin-film deposition. It showed an open-circuit voltage of 1.13 V, a short-circuit current of 10.63 mA/cm2, and a fill factor of 0.696. 

Toshiba claims 15.1% efficiency for polymer film-based large-area perovskite solar module

The result is claimed to be the highest efficiency ever reached for a large-area, polymer film-based perovskite photovoltaic module. The device has an area of 703 square centimeters and was fabricated through a new coating method.
