Highly stable deuterium (D) substituted A-site organic cations:
D-substituted formamidinium halides and D-substituted methylammonium halides. Hybrid perovskites contain organic amino group in which the H atom in N-H bond is highly active and can migrate and form HX (X=I, Br or Cl) with halide in its proximity, causing decomposition of the perovskites. The replacement of active H with its non-radioactive isotope D can effectively retards the decomposition reaction. These deuterated organic cations are demonstrated to be adaptable to any customers' own perovskite formulations but exhibit added stabilizing effect in addition to customers' own formulations.​​​​ See details in PNAS Nexus, 2023, 2, p160.

Transparent, defects-passivating, air-/water- repellent and decades-durable encapsulating materials for perovskite solar cells (PSC). Excellent choice for perovskite-water electrolysis and building-integrated photovoltaics (BIPV). Apply this specially formulated gel-like material on back side of PCS. It cures (hardens) within 3~5 days to protect vulnerable components in PSC as secured as ambers, and also prevents the shattering of TCO glass.

* HJT Si wafers (n-type) specially fabricated for perovskite-Si tandem cells with small pyramid size (1-1.5µm). Double side textured HJT wafer is adaptable to wafer manufacturing line, a realistic choice for the commercialization of perovskite-Si tandem cell. Reference and news report on perovskite-Si tandem cell using double side textured HJT wafer: Science 2023, 381, 59; 33.5% perovskite on textured Si tandem cells; Nature 2023, 623, 732; Science 2022, 377, 302
Price: $1500/pack, each pack contains three Si HJT wafers without ITO layers on either side (Note: n and p sides are indicated in the packaging box with the n side facing up and the p side facing down; the pyramid size ranges from 1~1.5µm) + one set (two pieces) of identical masks (see above picture for diagram) made from glass fiber (a material adaptable to UHV sputtering chamber) for patterned ITO coating on both sides and for patterned metal coating on the p side. The Si wafer size =210mm x 105 mm. Customers can coat ITO on both sides with desired thickness, and use laser to cut the wafer into smaller pieces. Typically, the n side appears more bluish, while the p side is more grayish.

Lead toxicity mitigation and laminated safety glass for perovskite solar cells: on-device lead sequestering solar EVA encapsulating film. Most high-performance perovskite solar cells contains water-soluble lead contents and non-tempered TCO glass. Thus, future commercialization of perovskite solar cells is subject to tight regulations by EPA, OSHA, US CPSC and government building glazing materials regulations. AA's proprietary lead-absorbing solar EVA film technology provides an excellent solution to form laminated safety TCO glass for BIPV (avoid glass shards) and to minimize lead leakage to environment or to residential area. See more details at Nature, 2020, 578, 555 and Nature Sustainability 2021, 4, 1038.
Price: $300/film, film size 156mm x 156 mm. Other customized sizes are also available per request. Make-to-order, lead time 2~4 weeks.
It is AA's perspective that future commercialized perovskite solar cells will likely adopt the following laminated safety glass configuration to meet safety regulations.

PV Efficiency Booster: This innovative coating solution can boost the power conversion efficiency of most solar cells for extra 0.1%~0.15% (absolute value). The active materials can be readily applied via spraying coating on the front side of most solar cells such as on the TCO glass side of perovskite solar cells, or on the TCO layer of perovskite-Si tandem cells, or on the front surface of metalized Si wafers (right before encapsulation).

Electrolyzers and components for CO2 reduction to value-added chemicals including ethanol, ethylene, acetate, formate and beyond
* We provide catalysts-coated cathodes, flow plates, anode coated with OER catalyst, gasket and full set of electrolyzers with standard active area of 5cm2, or 25cm2. The full electrolyzer can be assembled in the format of mebrane electrode assembly (MEA). Our patent-pending flow field design on cathode side can minimize the salting out and clogging of the gas flow channels. Our patent-pending cathode design allows the use of superhydrophobic PTFE film as the gas diffusion layer to minimize the flooding issue (in contrast to the case of using carbon paper as gas diffusion layer), while electrical current can still be delivered to the catalytic layer without suffering from high series resistance. Our electrolyzer system can achieve over 80% in Faradaic efficiency for electrocatalytic CO2 to C2 (mainly ethylene and ethanol) conversion when properly installed and used.
Full set CO2 to C2 products MEA system is configured as Titanium anode flow plate | OER catalyst-coated anode | Gasket | Membrane | CO2R catalyst-coated cathode | Gasket| Stainless steel cathode flow plate, with all inlets, outlets, bolts with insulating sleeves, screws, and a torque wrench. The active area can be 5cm2 or 25cm2 . We also offer individual parts and components including anode flow plate(titanium), OER catalyst-coated anode, gasket, CO2R catalyst-coated cathode, cathode flow plate (SS316), all with options for 5cm2 and 25 cm2 active areas. Please request quotation for active area of 25cm2 or other customized active sizes beyond 25cm2.
