Perovskite solar production

The Solar Energy Research Institute of Singapore (SERIS) upgrades equipment towards industrial production of perovskite-silicon tandem solar cells

The Solar Energy Research Institute of Singapore (SERIS) at the National University of Singapore (NUS) announces that it will upgrade its "Spatial Atomic Layer Deposition" (SALD) equipment. SoLayTec and SERIS have been working closely together for over a decade in the field of silicon solar cells. Recently, SERIS stated that SoLayTec will upgrade its existing ALD system using the latest technology of SALD BV, a Dutch technology start-up, for development of scalable perovskite-silicon tandem solar cells.

SERIS gears up perovskite solar cells for industrial tandem cell production

"Upgrading to the new SALD equipment brings us significant advantages," explains Dr. Shubham Duttagupta, Deputy Director of the Next-Generation Industrial Solar Cells & Modules Cluster at SERIS. The Dutch company SALD BV has developed a patented technology for applying precise coatings on an industrial scale that can be as thin as a single atom. An atomically thin coating, as can be achieved with the SALD technology, can make the cells significantly more robust. SERIS wants to take the leap “from lab to fab” with the new SALD machine.

New technique could help upscale the production of perovskite solar cells

Researchers from the City University of Hong Kong and the Southern University of Science and Technology in Shenzhen, China, have shown that a self-assembled monolayer can facilitate the formation of a large-area perovskite film using a blade-coating process, thus promote the upscaling of perovskite photovoltaic technology.

Researchers develop new technique to upscale the production of perovskite solar cells image

Researchers build perovskite solar cells with layers of material deposited on an underlying substrate. In adapting the high-speed blade-coating method for perovskite thin-film deposition, the researchers realized that the surface properties of the substrate are critical for large-area coating and perovskite growth. The current process leaves voids at the buried interface of the perovskite film that is detrimental to the device performance. “To solve this problem, we have screened various hole-transporting materials and found that self-assembled monolayers are a class of promising materials for the upscaling of perovskite devices,” said Alex Jen, a professor at City University of Hong Kong.

Researchers use high-speed flexography to produce more affordable perovskite solar cells

Last month, a group of Dartmouth College scientists developed what it refers to as 'the quickest reliable printing method for the manufacturing of perovskite solar cells'. The Dartmouth Engineering Lab's new method accelerates total processing time of solar charge transport layers (CTLs) by 60 times while maintaining reliability.

High-Speed Flexography yields affordable PSCs image

"Our method prints the layers of the solar cell with the speed and efficiency of a commercial newspaper printing press. This high manufacturing speed is important because it directly translates to lower cost per kWh, which will ultimately make solar energy more affordable for a larger population", said Dartmouth Engineering Professor William Scheideler

When will perovskite solar panels hit the market?

Perovskite solar panels have been under intensive R&D, and it seems as if commercial production is right around the corner. Some pilot-scale production lines are already functional, and companies are now ramping up production of perovskite panels, using various technologies.

UK-based Oxford PV, for example, recently announced that it has completed the build-out of its 100 MW manufacturing site in Germany, and it is on track to start full production in 2022. China's Microquanta Semiconductor perovskite panel factory is reportedly also nearing production (which should have started late 2020, but updates have not been available since), and another China-based company, GCL, has raised around $15 million USD to expand its pilot-scale production factory to mass production (100 MW).

CubicPV plans $1.1 billion investment under India's PLI scheme

CubicPV is said to be in talks with the Indian government to participate in the performance linked incentives (PLI) scheme for solar equipment manufacturers. CubicPV was established as a result of a collaboration between Hunt Perovskite Technologies and 1366 Technologies.

CubicPV reportedly plans to invest $1.1 billion to set up 10 GW solar wafer and cells manufacturing capacity in India over the next five years. Frank Van Mierlo, CEO of CubicPV, said that the company is planning to bring its innovative products in the solar equipment category, such as wafers and semiconductors, to India.

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."
