Summary of the clip:
Can you fabricate 18% efficiency perovskite solar cells in the open air, without a glovebox?
A major hurdle for the mass production of perovskite solar cells is the reliance on controlled, inert environments like gloveboxes to prevent degradation during fabrication. This clip showcases a significant breakthrough: the successful in-house fabrication of high-performance perovskite solar cells using a water-based Tin Oxide (SnO2) nano-ink under completely ambient conditions. This process entirely eliminates the need for a glovebox or any other controlled environment, paving the way for simpler, more cost-effective manufacturing.
The devices fabricated in open air demonstrate excellent photovoltaic characteristics, proving the robustness of the nano-ink ETL. They achieve a high open-circuit voltage (Voc) of around 1.1 volts and a strong short-circuit current (Jsc) near 22 mA/cm². Furthermore, the minimal hysteresis observed between the forward and reverse JV scans indicates a high-quality interface between the SnO2 ETL and the perovskite active layer, leading to efficient and stable charge extraction.
The results are not just promising; they are competitive. The champion device reached a power conversion efficiency (PCE) of approximately 17% in the forward scan and an impressive 18% in the reverse scan. These performance metrics match and even outperform those achieved with commercially available benchmark materials, validating the technology's potential to accelerate the industrial-scale production of perovskite solar cells.
In this short video, you can learn:
* How to fabricate perovskite solar cells using a water-based SnO2 ETL in ambient air.
* Key performance metrics achieved, including Voc, Jsc, and a champion efficiency of 18%.
* The significance of eliminating the need for a glovebox for scalable manufacturing.
📋 **Clip Abstract** This clip demonstrates the fabrication of high-efficiency (18% PCE) perovskite solar cells using PINA's water-based tin oxide ink entirely in ambient air. This breakthrough removes the need for expensive gloveboxes, showcasing a clear path to cost-effective, large-scale industrial production.

How can you process high-performance metal oxide transport layers below 120°C for flexible perovskite solar cells?
How can you process high-performance metal oxide transport layers below 120°C for flexible perovskite solar cells?
Metal oxide nano-inks offer a powerful solution to the challenges of stability and high processing temperatures that limit current perovskite solar cell manufacturing. Unlike organic layers that are unstable or traditional metal oxides that require over 450°C, these inks, featuring Zinc Oxide (ZnO), Tin Oxide (SnO2), and Nickel Oxide (NiO), are engineered for high stability, tunable energy alignment, and crucially, low-temperature processing.
The key to their effectiveness lies in their engineered properties. These nano-inks form highly uniform and transparent thin films at temperatures below 120°C, making them fully compatible with flexible plastic substrates. With optical transparency greater than 85% and strong interfacial performance, they ensure that minimal light is lost and that charge carriers are extracted efficiently, boosting overall device performance in both N-I-P and P-I-N architectures.
Designed for industrial scale-up, these inks possess a very low viscosity, making them fully compatible with a range of high-throughput deposition techniques. They can be applied using slot-die coating, blade coating, and spin coating, and are well-suited for future development in inkjet printing. This versatility ensures a smooth transition from laboratory research to large-volume industrial manufacturing, directly addressing a critical bottleneck in the commercialization of next-generation solar technologies.
In this short video, you can learn:
* The key advantages of metal oxide nano-inks over traditional organic and high-temperature inorganic transport layers.
* Specific performance metrics, including processing temperature (<120°C) and optical transparency (>85%).
* Compatibility with scalable deposition techniques like slot-die coating and inkjet printing.
📋 **Clip Abstract** PINA Creation's metal oxide nano-inks offer a breakthrough for perovskite and organic solar cells by enabling low-temperature processing without sacrificing performance. These inks are engineered for high stability, transparency, and compatibility with industrial-scale manufacturing methods.

Are defects in your transport layer always a bad thing? The answer might surprise you.
Are defects in your transport layer always a bad thing? The answer might surprise you.
In semiconductor device engineering, defects are typically viewed as detrimental, acting as recombination centers that trap charge carriers and reduce device efficiency and stability. This clip opens by addressing this critical concern, with a direct question about how defect levels are controlled in PINA's Tin Oxide (SnO2) nano-inks and what their impact is on the final device.
The response provides a fascinating and counter-intuitive technical insight. Rather than being a problem to be eliminated, the speaker explains that certain defects within their metal oxide films are actually beneficial. This discovery challenges conventional wisdom, suggesting that a zero-defect material is not necessarily the optimal goal for these specific applications.
The reason for this surprising benefit is rooted in charge carrier dynamics. The speaker clarifies that the presence of these engineered defects actually enhances charge mobility within the transport layer. This improved mobility facilitates more efficient extraction of electrons from the perovskite active layer, ultimately contributing to higher device performance. This paradigm shift from defect minimization to defect engineering is a key aspect of their material's success.
In this short video, you can learn:
* The role of defects in metal oxide nano-ink transport layers.
* Why certain defects can actually improve charge mobility and device performance.
* How PINA leverages this understanding to create more effective ETL materials.
📋 **Clip Abstract** In this clip, PINA's scientist reveals a surprising insight: defects in their tin oxide nano-inks are not a problem, but a feature. Learn how these defects can actually enhance charge mobility, leading to better-performing perovskite solar cells.
