International researchers have developed a silicon heterojunction PV cell with textured surfaces to accommodate the perovskite top cell. They optimized the rear transparent electrode to collect as much albedo as possible and achieved five different perovskite bandgaps by altering the iodide-to-bromide ratio in the perovskites, resulting in a higher open-circuit voltage.
Plunging regional solar tariffs reportedly prompted attempted renegotiations of agreed solar power prices with the result the kingdom made no progress towards its renewable energy goals in 2020.
Researchers in Saudi Arabia claim to have increased the efficiency of organic PV devices with diquat, a compound used in herbicide. The molecular diquat dopant increased optical absorption and the lifetime of electrical charges when light was absorbed.
Saudi Arabia’s futuristic Neom City will not use the cheapest sources of renewable energy, but those with the best chances of being dispatched, due to the storage potential of concentrated solar power. But several issues must be addressed to make the tech viable.
With the International Energy Agency publishing its latest five-year clean energy forecast today, pv magazine takes a look at the solar content of the 162-page document.
Scientists in Saudi Arabia have developed a new passivation process for n-type silicon solar cells, which they say could offer a simpler, lower-cost alternative to current processes used in manufacturing. The group fabricated wafers using this process with promising results, and now plans to integrate the process into a full silicon cell.
Scientists in Saudi Arabia headed outdoors to test the effects of the region’s high desert temperatures on the performance of small perovskite-silicon tandem cells in several different configurations. Their findings could offer new insight into selecting the best materials for long-term stability in the field.
Scientists at Saudia Arabia’s King Abdullah University of Science and Technology demonstrated an organic PV cell that can simply be printed onto a piece of paper. The cell set a new efficiency record for a fully inkjet-printed device, and its designers envisage applications in integrated medical sensors.
