Laser focus on perovskite film formation

Scientists in the United States developed a method to observe the structure and mechanics of a perovskite material during its synthesis and transition from liquid precursors to a solid thin film. The group says its work will provide new insight into manufacturing and the development of reliable large-scale processes for perovskite solar cell production.

Strong potential for inorganic perovskites

Scientists in the United States have developed a method to compare the performance and number of defects in different perovskite cell materials. Based on simulations and work with prototype materials, the group finds that all-inorganic materials have higher potential efficiency than their more widely researched organic-inorganic counterparts.

The Hydrogen Stream: Indian group makes bold green hydrogen claim as plans emerge for production capacity in Spain

The renewables-powered sustainable hydrogen announcements have come as a group of international researchers made controversial claims about the potential of gas-fired blue hydrogen to be part of the climate change solution.

‘Low-cost renewable hydrogen may already be in reach’

If the three record-busting low solar price tariffs recorded in the Middle East in the past 18 months are to be believed, renewables-powered hydrogen in prime sites in the region could already compete with gas-plus-CCS production, according to IRENA. Has the Gulf discovered the new petrol?
