An inverted perovskite cell with 22.3% efficiency

Saudi researchers have developed a cell which is said to exhibit improved structural and optoelectronic properties as well as enhanced carrier mobility and diffusion lengths. The feat was achieved by reducing voltage losses using a new passivation technique.

Watch how to improve perovskite solar cells in 2D!

Saudi researchers claim to have improved the thermal stability and moisture resistance of such devices by replacing 3D hybrid perovskite with two-dimensional compounds. They used organic compound ethanolamine, which is said to provide better results in slowing down the hot-carrier cooling process.

Germany tops global league table for renewable energy

A list compiled by a British price comparison website draws upon data from German company Statista which shows clean energy – including hydro – made up 12.74% of the nation’s power mix at the end of September.

The weekend read: Your guide to market growth in 2020

Some 15 countries are likely to be able to lay claim to the status of being members of solar’s “gigawatt club” in 2019, according to conservative projections from BloombergNEF. Nonetheless, PV suppliers, developers and service providers are always on the lookout for new pockets of growth. To kick off 2020, pv magazine’s global team of correspondents and editors have highlighted 10 “fast-growing” solar markets to evaluate where the opportunities, and potential risks, lie.

Tungsten disulfide helps organic solar cell reach 17% efficiency

Researchers from Saudi Arabia’s King Abdullah University of Science and Technology claim to have developed a highly performant organic PV cell using tungsten disulfide flakes a few atoms thick. The stability of the device, however, is still to be evaluated.

Saudi Arabia’s 300 MW Sakaka solar plant comes online

The PV facility was completed a month and a half ahead of schedule by Saudi energy company ACWA Power. The project will sell power at $0.0236/kWh.
