Focus on the negatives: A new path to highly efficient tandem cells

Scientists in the U.S. and South Korea have identified what could be a new route to high-efficiency perovskite-silicon tandem solar cells. Through engineering negatively charged particles in the passivation layer, the group made a tandem cell with 26.7% efficiency. With further tweaks to the silicon layer they expect to be able to surpass 30%.

Jinko joins Covid-19 fight

The module giant today announced it will donate a million items of personal protective equipment to the European and Asian countries currently battling the spread of the novel coronavirus.

South Korea’s president makes zero-carbon economy election pledge

For the first time ever, President Moon Jae-in’s ruling Democratic Party has vowed to achieve a zero-carbon economy, just weeks ahead of the April 15 legislative election.

Hybrid tandem quantum dot solar cell with 12.8% efficiency

South Korean scientists have produced an organic, hybrid-series tandem PV device that combines quantum dots and organic bulk heterojunction photoactive materials. They claim that the cell has the highest efficiency among all reported colloidal quantum dot cells, including single-junction devices and tandem devices.

A stretchable, transparent solar cell with 8% efficiency

Korean scientists have unveiled a colorless device made of silicon microwire composites. The enhanced light absorption of the cell, the researchers claim, is due to the re-absorption of light by the microwires, which also benefit from an enhanced electric field.

Achieving 21.2% efficiency in a perovskite cell thanks to food additives

South Korean scientists have developed two perovskite solar cells based on a polymer made with peppermint oil and walnut aroma food additives, respectively. The new dopant‐free hole transport polymer is said to enable longer durability of the devices and to prevent lead-leakage.

Trade shows postponed over coronavirus fears

As the contagion continues to spread, its impact is beginning to be felt on the solar industry outside China with the cancellation or postponement of major trade shows and conferences that were set to take place over the next few weeks.

Korean researchers announce flexible CIGS solar cell with 20.4% efficiency

The thin-film cell was manufactured through a low-temperature process and doping with alkali elements.

Quantum dot hybrid HTJ cell with 12.82% efficiency

South Korean researchers have developed a hybrid tandem solar cell based on quantum dots and organic bulk heterojunction (BHJ) photoactive materials. They claim that the cell could reach an efficiency rate of around 15% if they continue to reduce energy losses in the quantum dot cell and enhance near-infrared absorption.

Hanwha officially exits polysilicon business

Hanwha Solutions has confirmed that it will shut down its polysilicon business over the course of the next year, only a week after saying that it was still evaluating its plans for the sector.
