UK-based perovskite material developer Helio Display Materials announced that it has raised $4.75 million in its Series A funding round. The funds will be used to significantly expand the company's team and also a move to custom-built labs.

Helio Display Materials was spun-off from both Oxford and Cambridge University, to commercialize photoluminescent and electroluminescent perovskite-based materials for the display industry. In June 2020 we posted an interview with Helio's CEO, Simon B. Jones, discussing the company's technology and business

Researchers from France's Institut Photovoltaïque d'Île-de-France (IPVF), EDF R&D and C2N have fabricated a mini perovskite solar module, via deposition of tin oxide as an electron extraction layer using chemical bath deposition (CBD), a low-cost and solution-based fabrication process.

Using this simple low-temperature deposition method, highly homogeneous SnO₂ films can reportedly be made in a reproducible manner. In addition, the perovskite layer was prepared by sequentially slot-die coating on top of the n-type contact. The symbiosis of these two industrially relevant deposition techniques can allow for the growth of high-quality dense perovskite layers with large grains.
