Harvesting electricity from shadow

Researchers in Singapore have created a device that can produce electricity from the contrast in illumination between lit and shadowed areas under weak ambient light. Although not directly related to solar, this new technology opens up new horizons for producing clean energy under indoor lighting conditions.

Mini perovskite module with 18.13% efficiency

Scientists from Singapore have developed semi-transparent perovskite solar cells that can be easily integrated into a range of urban contexts, including building facades, gates and windows. The 21cm2 mini panels are made of perovskite solar cells based on methylammonium lead iodine (MAPbI3), with an efficiency of 20.28% for 0.16 cm2.

Covid-19 pandemic puts 150 GW of PV, wind at risk in Asia

Up to 150 GW of PV and wind projects could be postponed or canceled throughout the Asia-Pacific region by 2024 if the coronavirus-triggered recession continues beyond the current year, according to new research by Wood Mackenzie.

Chinese developer buys back three-year senior notes issued three months ago

The board of bailed-out Singyes Solar has bought back $18.4 million worth of notes issued in Singapore in late December and also hoovered up $240,000 worth which were unclaimed in the fundraising round.

Lithium-sulfur solid-state batteries promise fire safety at high performance

The scramble for new battery solutions is accelerating as researchers from Singapore tout an electrolyte which which they say produces highly stable lithium-sulfur batteries that maintain performance metrics – a task which has proven tricky thus far.

Change at the top for Meyer Burger after €37m loss

The Swiss PV equipment supplier posted the loss for 2019, citing increasingly fierce competition in China, and plans to continue a strategic realignment of its business with the options including the establishment of a European PV manufacturing operation.

Raising crops in PV facades

An international research group has analyzed the visual impact of PV facades on buildings which include crop cultivation. Architects, PV specialists and farmers were surveyed and the results showed broad acceptance of such projects.

Hot charge extraction to push perovskite efficiency

With the absorption of ‘hot’ charges, which lose their energy faster than it can be absorbed by any convention technology, solar cells could become massively more efficient. An international group of scientists has developed a method to examine the bond between a perovskite and charge extraction layer, and determine the most suitable materials for hot charge extraction in a solar cell.

Hot news on harvesting electrons in perovskites

An international research group claims to have developed a new bulk perovskite semiconductor material that can capture the excess energy of hot electrons. The material is said to rapidly absorb as heat energy which would otherwise be wasted. With the harvesting of hot electrons, the maximum theoretical efficiency for hybrid-perovskite solar cells could increase from 33% to 66%.
