According to a report by Kyodo News on January 21, Toshiba announced on the 21st that it has successfully achieved cuprous oxide for the first time.solar energyTransparency of the battery. It is envisaged to be applied to products that can be superimposed on widely available crystalline silicon solar cells to improve power generation efficiency. Cuprous oxide, an oxide of copper, is said to reduce costs significantly because copper is cheap to purchase.

According to the report, it has been confirmed that the cuprous oxide solar cells placed above can transmit light, so that the crystalline silicon solar cells placed below can maintain high power output. It is said that by precisely controlling the amount of oxygen in the preparation of cuprous oxide thin films, transparency, which has been difficult in the past, has been achieved.

At present, "multi-junction" products that combine solar cells of different properties use gallium arsenide semiconductors. By substituting cuprous oxide solar cells, Toshiba expects manufacturing costs to drop to 0.1% to 1%.

Toshiba's current self-produced crystalline silicon solar cells have an energy conversion efficiency of 17.6%. The company aims to increase the conversion efficiency to 30% in three years with the help of multi-junction solar cells using cuprous oxide.
