APAC Sustainability "Perovskite & Space Solar Series: Outlook for Japanese..."

and, he said there were commonalities in the failures

experienced by Japanese companies in liquid crystal displays, solar cells, and

semiconductors. He expressed the view that a risk-averse pattern of behavior, in which

companies avoid large-scale investment at the critical stage of a market taking off, has

led to a decline in Japan's competitiveness. From the perspective of technology

management, he stated his belief that investment decisions at the early stage when

technologies are emerging are extremely important, and that perovskite solar cells are

currently at exactly that stage. He also pointed out that perovskite is a Japan-originated

technology and stressed the strong importance of foundational patents. Regarding

patents, he confirmed that there has been an increase in filings by Chinese companies

but indicated that what is important is not only the number of filings, but also who holds

the early foundational patents and the patents related to mass-production technologies.

He also expressed the view that Chinese companies may have acquired a large number

of patents related to mass-production processes.

What are perovskite solar cells?

A type of solar cell whose power-generating layer is made mainly from iodine,lead,

and tin

Characteristics: lightweight and flexible, compatible with low-light

conditions,and highly efficient.

Issues being addressed 1: Rapid degradation occurs when exposed to water,

oxygen, or high temperatures of 50.0°C or above. Continuous power generation

for more than 1,000 hours in a 60.0°C environment has been achieved with the

crystal structure and encapsulation technologies.

Issue being addressed 2: It is difficult to make large panels uniform. Uniform
