Japan’s policies for carbon neutrality in 2050
 In October 2020, Japanese government declared that it aims to achieve carbon neutrality by 2050.
 The Ministry of Economy, Trade and Industry in collaboration with other ministries and agencies,
formulated the “Green Growth Strategy through Achieving Carbon Neutrality in 2050”.
 This strategy specifies 14 promising fields that are expected to grow and provides action plans forthem from the viewpoints of both industrial and energy policies.

Background of the project

Location constraints for solar power generation
 Currently, it is estimated that a cumulative total of about 1.1TW of solar power generation has been
installed worldwide.
 In Japan, many solar power generation have been already installed per national land area.
 In regions such as East Asia and Southeast Asia, where populated area suitable for installing solarpower generation are limited, further expansion of solar power generation installations is becoming
difficult.

Background of the project

Carbon Neutral City achieved by Next-generation PV
 One promising solution is practical application of lightweight, flexible, highly efficient next-generation
photovoltaics that can be installed on house and building roofs where difficult to install conventional
photovoltaics. IEA’s estimation show huge potential.
 Perovskite photovoltaics are expected to be a next-generation photovoltaic that meets theseconditions. Perovskite modules has potential of significantly lighter than other types, and can even be
fabricated on flexible substrates, which will be easily installed in urban areas.

Next-Generation Solar Cell Development
 Overcoming location constraints is the key to expanding solar power. Therefore, this project willdevelop next-generation photovoltaics (perovskite photovoltaics).
 This project works on three stage from R&D, through developing the underlying technologies (such as
high efficiency, large size module and durability) related to commercialization and the production
system, and all the way to demonstration and practical use, with aiming for the social implementationof Perovskite photovoltaics by 2030.

Theme 1: Development of basic technology for next-generation solar cells
R&D will be carried out on the optimum material composition of perovskite solar cells, elemental
technologies for conversion efficiency and reliability, and techniques for analysis/evaluation.
(Entrustment, FY2021-FY2025)
 National Institute of Advanced Industrial Science and Technology (AIST)

Theme 2: Next-generation solar cell practical application development
R&D will be carried out for realizing elemental technologies for manufacturing processes (such as
coating processes, electrode formation, and sealing processes) for scaling up products anddurability, cooperated with Universities and AIST (Theme1).
