Tandem cells head outdoors

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.

A cell so thin, it can rest on a soap bubble

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.

Global green hydrogen project pipeline reaches 50 GW

International thinktank IEEFA says there are 50 viable green hydrogen projects under development with an estimated renewable energy capacity of 50 GW and the potential to produce 4 million tonnes of the fuel annually.

Wider wind-solar complementarity would mean less need for storage

A study from the Lappeenranta University of Technology states a deeper complementarity between solar and wind generation may favor renewables deployment reducing the need for stronger developments in storage technology. Combining solar with wind more widely could also reduce the need for ramping and improve the reliability of energy supply, say the researchers.

Redox flow battery powered by perovskite solar cells

An international team has developed an integrated solar flow battery which has been suggested as ideal for off-grid locations. The device, which combines energy conversion and storage in one unit, can be used for lighting and recharging cell phones.

Saudi Arabia outlines new provisions for rooftop PV

The regulations will force power distributors to give more help to homeowners and businesses willing to go solar. The new framework will apply to PV systems ranging in size from 1 kW-2 MW and to all energy consumers.

Spherical monocrystalline solar cells with 18.93% efficiency

The spherical 3D cells can reportedly generate around 101% more power than conventional flat solar cells. Measurements have also shown that the spherical cells provide a 10% lower maximum temperature compared to flat cells, while accumulating less dust.

Solar costs have fallen 82% since 2010

The levelized cost of energy generated by large scale solar plants is around $0.068/kWh, compared to $0.378 ten years ago and the price fell 13.1% between 2018 and last year alone, according to figures released by the International Renewable Energy Agency.

Harvesting atmospheric water to cool down PV panels

Scientists from Saudi Arabia have proposed a new PV panel cooling technique which employs an atmospheric water harvester. The device uses waste heat from the PV panel to collect atmospheric water at night and then releases it during the day to cool down the module. The researchers claim the device may also be improved to produce liquid water, which could be used for the cleaning of the modules.
