Patents

From a laboratory result to protected technology

Publishing is only half of the story. Alongside the papers, the group protects the chemistry and the device engineering behind its perovskite photovoltaics — the precursor formulations, the tin-based absorbers, the ways of growing the film, and the layers that carry and protect it. Sixteen patents are on record, six of them already granted, all filed in China through the Southern University of Science and Technology.

Portfolio

Patents

The group's patented technology, filed through the Southern University of Science and Technology and covering the same ground as the papers: precursor chemistry, tin-based perovskites, film formation, electron transport layers and device encapsulation. All are Chinese filings, so each entry is listed under its title as filed, with our English rendering underneath. The list is newest first, and 6 of the 16 are already granted.

Our patents are only useful with people who can move them

A granted claim protects an idea; someone still has to scale it. We are looking for the people who will.
