We are absolutely thrilled to announce that an Ossila student employee, Oluchi Emenike, has won a Regional award for Student Employee of the Year (SEOTY) in the Commercial Impact category. This is the third time that one of our student employees has won a SEOTY award! Read about our previous SEOTY award-winning students.
The SEOTY awards have been held annually in the UK since 2002. As the UK’s largest student awards, they honour the extraordinary contributions and accomplishments of students who have flourished in combining their academic and part-time work duties.Read more...

Surface energy is a material property that can be used to explain why solutions wet differently on different surfaces. This is important for almost any solution processing technique. Values of surface energy can be calculated using contact angle measurements, allowing for easier optimisation of wetting.
In the latest guide by our PhD student Emma Spooner, we discuss how surface energy can be defined, what impacts the value, and the different methods that can be used to calculate it. Learn more here - A Guide to Surface Energy.

Spin coating is a great technique to easily deposit thin films, but is easier for some materials than others. Solutions with poor solubility, or those that are very volatile/viscous can cause difficulties when spin coating - especially if they don’t wet well to the substrate. This means that non-uniform or incomplete films can be formed, often leading to poor device performance.
In the latest guide by our PhD student Emma Spooner, we discuss some of the reasons why non-uniform films happen, and the techniques that you can use to improve them in order to achieve better device performance. You can read more here - Spin Coating: A Guide to Coating Difficult Solutions.

As part of our continuous mission to enable more scientific research, we are happy to announce that several of our OPV & OLED substrates will now have permanent price reductions. Due to increased support and demand from our customers, we have been able to reduce costs by scaling up our manufacturing and production processes - thus allowing us to provide you prices that are even more affordable!
The following substrates (100 pieces) will now be priced at £199 (previously £425):
- S101: 6-Pixel ITO Glass OLED Substrates (Pixelated Anode)
- S171: 6-Pixel ITO Glass Substrates (Pixelated Cathode)
- S211: 8-Pixel ITO Glass Photovoltaic Substrates
In addition, our ITO substrate packs have also had a massive price reduction and are now £279 (previously £500).Read more...

Spin coating is a simple and straightforward thin-film deposition technique. As such, it is a great technique for beginners due to its relatively low barrier-to-entry.
However, to become highly skilled at spin coating, it is beneficial to understand how the background physics involved (in terms of physical factors and solution properties) can affect the films you produce, and how they dictate eventual film thickness.
In the latest guide by our PhD student Emma Spooner, we cover the basic steps of spin coating and explore a couple of models on film thickness equations. You can read more here - Spin Coating: A Guide to Film Thickness.

A material's properties are not only determined by what it is made of - the size of a material can also affect how it behaves. When reduced down to nanoscale form, certain materials will display properties that are different to what they show in their bulk form.Read more...

Earlier this week, we published a guide on the factors that influence the degradation of perovskite solar cells. As a follow-up to it, we now have a guide on several methods that have been found to help improve perovskite solar cell stability and durability.
These methods can also be divided into two categories: Intrinsic (which includes using mixed cations/halides, additives, and 2D perovskites) and extrinsic (e.g. encapsulation). You can learn more about these by reading Perovskite Solar Cells: Methods of Increasing Stability & Durability.

In the field of photovoltaics, it is common knowledge that perovskite solar cell stability and durability still has room for improvement. Although recent studies have shown promising advancements, perovskite solar cells still do not reach the standards defined by the International Electrotechnical Commision (performing well under non-lab conditions, and withstanding those conditions for over 1000 hours consistently).
As such, the durability of perovskite solar cells needs to be improved further before they can competitively enter the current market. The first step is towards this is to gain a thorough understanding of the exact factors that cause the perovskite crystal to undergo degradation.
These factors are explored and discussed in our latest guide - Perovskite Solar Cells: Causes of Degradation.
