Microquanta reaches 21.86% efficiency of 810 cm² perovskite module

Microquanta has reportedly announced that its 810 cm² medium-sized perovskite module has achieved a certified full-area power conversion efficiency of 21.86% (average of forward and reverse scan: 21.83% forward, 21.89% reverse), as verified by the National PV Industry Measurement and Testing Center (NPVM).

The company called this a new efficiency record for perovskite modules of this size. Microquanta stated that the module incorporates its proprietary cryogenic laser repair technology, which in addition to significantly enhancing module efficiency also greatly improves module stability. Microquanta plans to apply this technology to its upcoming GW-scale perovskite production line, set to commence operations in March this year. The company has set a target of surpassing 20% conversion efficiency and achieving a 25-year lifespan for large-area modules with a size of 2.88 m².

New European project aims to improve tin halide perovskite solar cells for BIPV

Smartline PV is an innovative Horizon Europe project focused on improving the efficiency and stability of tin halide perovskite solar cells, a promising alternative to toxic lead-based systems. The project focuses on overcoming key challenges with a fast, robust, and scalable plasma-assisted crystallization technology, which ensures high-quality tin perovskite films through precise control of nucleation and growth. This innovative process benefits from high speed, low temperatures, and tailored precursor chemistry.

Additionally, Smartline PV will implement tailored interlayers to further enhance solar cell efficiency and stability, along with novel device concepts for flexible, color-selectable tin perovskite solar cell modules. Smartline PV's lead-free technology aims to achieve efficiencies of 22%, significantly reducing energy consumption and manufacturing costs compared to traditional high-temperature thin film processes.

New strategy stabilizes wide-bandgap perovskites and enables improved Cu(In,Ga)Se2 tandem solar cells

Researchers from China's Westlake University, Advanced Solar Technology Institute of Xuancheng and Turkey's Marmara University have addressed the stability issues of perovskite solar cells (PSCs) by developing a divalent cation replacement strategy that mitigates ionic migration while limiting phase segregation. 

Using the new method, the scientists fabricated a champion cell that showed a PCE of 23.20% (certified 22.71%) for a single-junction PSC with a bandgap between 1.67 eV and 1.68 eV. Furthermore, a PCE of 30.13% was obtained for mechanically stacked perovskite/Cu(In,Ga)Se2 tandem devices, and a PCE of 21.88% for transparent perovskite devices. Finally, they obtained a steady-state PCE of 23.28% (certified 22.79%) for flexible monolithic perovskite/Cu(In,Ga)Se2 tandem cells.

New one-step method combines photolithography and solution processing to prepare superior perovskite single crystal arrays under ambient conditions

Halide perovskite single crystals have demonstrated enormous potential for next-generation integrated optoelectronic devices. However, there is a lack of
a facile method to realize the controllable growth of large-scale, high-quality, and high-resolution perovskite single crystal arrays on diverse types of
substrates, which hinders their application in practical scenarios.

HZB and Humboldt University reach 24.6% efficiency of CIGS-perovskite tandem cell

Scientists from HZB and Humboldt University Berlin have reported a CIGS-perovskite tandem cell that sets a record with an efficiency of 24.6%, certified by the independent Fraunhofer Institute for Solar Energy Systems.

The team's new tandem solar cell combines a bottom cell made of CIGS with a top cell based on perovskite. By improving the contact layers between the top and bottom cells, they were able to increase the efficiency to 24.6%. This cell was the result of a successful team effort: the top cell was fabricated by TU Berlin master's student Thede Mehlhop under the supervision of Stefan Gall. The perovskite absorber layer was produced in the joint laboratory of HZB and Humboldt University of Berlin. The CIGS sub-cell and contact layers were fabricated by HZB researcher Guillermo Farias Basulto. He also used the high-performance cluster system KOALA, which enables the deposition of perovskites and contact layers in vacuum at HZB.
