Mitsubishi and Japanese university offer peer-to-peer trading alternative to FIT payments

Blockchain systems are being tested as a means of offering solar households revenue for excess power they generate, now the FIT program has ceased.

The week in perovskites

As a focus of research at leading institutes the world over, new developments in the perovskite field come thick and fast almost every week. From x-ray observations on a nanoscale to financing and plans for mass production, pv magazine is bringing together some of the most exciting developments of recent weeks.

New perovskite promises 38.7% efficient tandem cells

Japanese researchers have identified a perovskite material with a strong band edge gap and high stability which they say could offer 38.7% efficiency if used in the correct tandem cell architecture.

Replacement for CdTe: Copper-nitride conductor for thin film discovered

A novel method developed in Tokyo, Japan, allows a nitride crystal to grow, which can function as both an n- and p-type conductor. The material can replace cadmium-telluride (CdTe) in thin films, and make such solar cells more environmentally friendly, while enabling greater efficiencies, the researchers claim.
