Researchers develop semi-transparent perovskite solar cells with 21.68% efficiency

Researchers from the Korea Institute of Energy Research (KIER), Korea Research Institute of Standards and Science, Jusung Engineering and the Jülich Research Center have reported an advancement in the stability and efficiency of semi-transparent perovskite solar cells.

The semi-transparent solar cells achieved an impressive efficiency of 21.68%, which is said to be the highest efficiency to date among perovskite solar cells that use transparent electrodes. Additionally, they showed remarkable durability, with over 99% of their initial efficiency maintained after 240 hours of operation.

Researchers develop triple-junction perovskite–perovskite–silicon solar cell with power conversion efficiency of 24.4%

Researchers at the Karlsruhe Institute of Technology (KIT), Institute for Solar Energy Research Hamelin (ISFH) and Leibniz University Hannover have designed triple-junction perovskite–perovskite–silicon solar cells with a record power conversion efficiency of 24.4%.

Optimizing the light management of each perovskite sub-cell (∼1.84 and ∼1.52 eV for top and middle cells, respectively), the team maximized the current generation up to 11.6 mA cm−2. Key to this achievement was the development of a high-performance middle perovskite sub-cell, employing a stable pure-α-phase high-quality formamidinium lead iodide perovskite thin film (free of wrinkles, cracks, and pinholes). This enabled a high open-circuit voltage of 2.84 V in a triple junction. Non-encapsulated triple-junction devices retain up to 96.6% of their initial efficiency if stored in the dark at 85 °C for 1081 h.

Researchers develop novel lead-free antimony-based perovskite solar modules

Lead-halide perovskites hold great promise as the next generation of PVs, but unstable lead exposure through gas, water, and soil accumulation could have detrimental consequences if not properly controlled and recycled as perovskite use expands globally. There are also stability issues limiting operational lifetime for lead-perovskite devices themselves. Researchers have attempted to replace lead with slightly less toxic tin, but thus far tin-based perovskites still suffer from air instability. Without breakthroughs in stability and environmental safety, scaling perovskite solar technology could flood our waste stream with hazardous materials. Now, researchers from CHOSE (Centre for Hybrid and Organic Solar Energy) at the University of Rome Tor Vergata have addressed the concerns regarding toxicity and recyclability associated with the lead contained in perovskite solar cells.

The scientists may have found a solution in a new lead-free antimony-based perovskite solar cell design. Their recent research demonstrates a mixed-cation perovskite-inspired material (PIM) that boosted efficiency by 81% compared to conventional cesium-only antimony solar cells, while also exhibiting unmatched stability.

Researchers use zinc additives for efficient perovskite solar minimodules

Researchers at the University of North Carolina at Chapel Hill and CubicPV have developed mini solar modules based on perovskite cells treated with zinc trifluoromethane sulfonate [Zn(OOSCF3)2]. The scientists found that using a small amount of this zinc salt in the perovskite solution can address the issue of interstitial iodides, which are the most critical type of defects in perovskite solar cells that limits efficiency and stability. The zinc salt helps control the iodide defects in resultant perovskites ink and films. 

The scientists explained that this is a low-cost material that is used as an additive at a very small percentage in perovskite inks and that its use makes perovskite module fabrication more reproducible, which helps to also make it cheaper.

Netherlands reveals details of incentive scheme for PV manufacturing

The Dutch government has drafted a public proposal to support the production of heterojunction and perovskite-silicon tandem modules, as well as building- and vehicle-integrated PV panels, with a maximum allocation of €70 million ($75.1 million) per solar manufacturing project. Rijksdienst voor Ondernemend Nederland (RVO), the state-run agency that manages the SDE++ program for renewable energy in the Netherlands, has publicly proposed the idea of supporting the production of solar panels, storage systems and electrolyzers. The new incentive scheme, “Investeringssubsidie maakindustrie klimaatneutrale economie” (IMKE), will fund a portion of the capital expenditure needed to build factories for the three clean energy technologies.

The RVO said that the incentives for the production of PV panels will be limited to products for building-integrated (BIPV) and vehicle-integrated (VIPV) applications, as well as heterojunction modules or perovskite-silicon tandem panels.

Researchers develop a perovskite-based 3D printing ink that could power next generation OLED devices

Researchers at Lawrence Berkeley National Laboratory (Berkeley Lab), led by Prof. Peidong Yang, have developed a new 3D printing ink based on perovskite materials, that exhibits near unity photoluminescence quantum yield (PLQY). Interestingly, as it is a 3D printable ink, it is possible to create luminescent objects from it, as seen in the image below:

The researchers brand the new ink as 'supramolecular ink', and say it is produced without any rare metals. It is a combination of several powders containing hafnium (Hf) and zirconium (Zr), and is made at room temperatures. In a process called supramolecular assembly, tiny molecular building block structures are self-assembled within the ink. These supramolecular structures enable the material to achieve stable and high-purity synthesis at low temperatures.
