Researchers show that manipulation of antisolvent application rate can help create efficient and reproducible PSCs

Researchers from the Emerging Electronic Technologies Group of Prof. Yana Vaynzof at Germany's Technische Universität Dresden have found that fundamental processes that occur during perovskite film formation strongly influence the reproducibility of the photovoltaic devices.

When depositing the perovskite layer from solution, an antisolvent is dripped onto the perovskite solution to trigger its crystallization. "We found that the duration for which the perovskite was exposed to the antisolvent had a dramatic impact on the final device performance, a variable which had, until now, gone unnoticed in the field." says Dr. Alexander Taylor, a postdoctoral research associate in the Vaynzof group and the first author on the study. "This is related to the fact that certain antisolvents may at least partly dissolve the precursors of the perovskite layer, thus altering its final composition. Additionally, the miscibility of antisolvents with the perovskite solution solvents influences their efficacy in triggering crystallization."

China's GCL raises over $15 million for 100 MW mass production line for perovskite solar cells

GCL Optoelectronics Technology Holdings, a subsidiary of China’s Golden Concord Holdings Limited (GCL), recently closed a new financing round to enable it to expand its pilot perovskite solar module production to the mass production level.

According to various reports and news, the company has announced raising more than RMB 100 million (around $15.36 million) for a 100 MW mass production line for these modules.

Energy Materials Corporation achieves high-speed, roll-to-roll printing of conductors on flexible glass for perovskite solar panels

Energy Materials Corporation (EMC), developer of high-speed roll-to-roll manufacturing of solar energy panels, recently announced that it has developed an enabling process to print transparent conductors as part of the scale-up of its inline manufacturing process.

Roll-to-roll printing of metal conductors on Corning Willow Glass (flexible glass) at 60 meters per minute reportedly sets a world speed record for printing flexible electronics on glass. The process surpasses the company's goal of achieving less than 5% loss in the transmission of light though the conductive layer.

EMC discloses plans for roll-to-roll printing of perovskite PV on glass

Energy Materials Corporation (EMC) has stated its plans for roll-to-roll printing of perovskite PV on glass.

The plan is backed by two partnerships—one with the Eastman Kodak Company for roll-to-roll printing and another with glass and ceramics company Corning, for flexible glass. EMC’s funding includes a $4 million research grant from the Solar Energy Technologies Office of the U.S. Department of Energy.

KRICT team demonstrates 'roll-to-roll' manufacturing of flexible perovskite solar cells

Researchers at South Korea's KRICT, led by Seo Jang-won, have demonstrated pilot-scale "roll-to-roll" (R2R) manufacturing of flexible and light perovskite solar cells.

As an eco-friendly antisolvent, Seo's team introduced tert-butyl alcohol (tBuOH), a colorless solid, which melts near room temperature and has a camphor-like odor, for R2R processing through cooperation with VTT Technical Research Centre of Finland.
