CO2-free electricity
New Horizons for Solar Power with Next-gen Perovskite Solar Cell PVs

To drive a shift toward the installation of PV systems and renewable energy being used as a primary option, we enable efficient electricity production using solar energy that can be leveraged in many urban locations.

Organic-inorganic Hybrid PV Team

Research themes

  • Material and process development for innovative ultra-light weight and high efficiency PVs using perovskite solar cells
  • Development of low-production-energy fabrication technology to reduce CO₂ emissions
  • Branching out in applications for perovskite and organic PVs

Concept for social contributions and implementation

We will develop an ultra-lightweight panel that offers equivalent power generation capacity to Si PVs, thereby realizing PV devices that can be installed on factory complexes and other buildings with weaker structures.

MURAKAMI Takurou

I first developed an interest in solar energy when I was in high school. I was fascinated to learn that photosynthesis occurs in the plants that grow all around us but with a conversion efficiency of just 3%. I then considered that humans should use this abundant energy source more effectively. Solar power generation is a highly flexible approach for power generation with renewable energy, in terms of the range of locations where devices can be installed. I hope we can contribute to the realization of a system for the local production and consumption of energy.
