Asia Air Survey Co., Ltd. Exhibit overview image1

Traditional forest inventory techniques require a lot of field work. Workarounds exist but at the expense of accuracy. Here, field work for forest inventory in Malawi (Photo: Asia Air Survey)

Asia Air Survey Co., Ltd. Exhibit overview image2

Instead, we are introducing an automated inventory technique that utilizes airborne laser scanning in order to improve accuracy and reduce field work.

Airborne laser is a technology for measuring the shape of the terrain, buildings, forests, etc. by mounting a laser scanner on a plane or helicopter. Asia Air Survey is developing a method to evaluate forest resources using this technology. Information on the color tone of the vegetation, canopy shape, and tree height is obtained by scanning forests from above. By repeating this every few years, it is possible to measure the growth of each individual tree and hence to calculate its carbon accumulation. Outside Japan, the carbon balance of forests is generally estimated by multiplying the variation of forest area by the unit carbon amount of each tree species or forest type, but by using laser data, more accurate carbon assessment can be achieved, which can result in higher quality credits.

New Solar Cells to Boost Renewable Energy

Light, film-type perovskite solar cells and Cu₂O tandem solar cells with high power generation efficiency

Toshiba Corporation and Toshiba Energy Systems & Solutions Corporation Exhibit overview image1

Perovskite cells and tandem cells meet different needs in urban areas

If we are to achieve carbon neutrality, we need to deploy more, and more efficient, photovoltaic power generation. However, current silicon (Si) solar cells are heavy and inflexible, which restricts where they can be installed, and there are limits to how far they can be improved. Two solar cells that Toshiba Group is developing will change this. Film-type perovskite solar cells are light, thin and flexible, and can be installed in buildings and locations inaccessible or unsuitable for Si cells. The Cu₂O tandem solar cell places a transparent copper oxide (Cu₂O) solar cell over a Si solar cell, boosting generation efficiency and producing much more power by area.
