Technology to convert solar energy transmitted from outer space to the earth into electric power
Space solar power system is a technology that converts solar energy transmitted from outer space to the earth into electric power.
As a step toward the realization of a sustainable society, we aim to utilize solar energy in outer space, which is an overwhelmingly clean and inexhaustible energy source whose practical applications have become apparent.
To utilize solar energy, we will combine technologies to efficiently convert sunlight into lasers or microwaves in geosynchronous satellite orbits, to transmit beams of uniform surface intensity to the ground without being affected by atmospheric fluctuations, and to efficiently convert high-intensity beams into electric power.
In addition to energy transmission from space, it is expected to be used as a power distribution system for mobile devices such as drones and automobiles, a power distribution system using microgrids, and power supply for remote islands and evacuation centers in the event of a disaster.
NTT Space Environment and Energy Laboratories are looking for researchers and engineers from several fields to help us find new solutions to pressing worldwide issues.
