🧪 New paper alert! We present a solvent-guided strategy to boost doping efficiency in n-type polymers via phase-selective doping. Predicting microstructure with solubility parameters? Yes, it’s possible.😉 🔗doi.org/10.1039/D4MH01805B

Leveraging solvent affinity for phase-selective doping to enhance doping efficiency in a DPP-based...

Phase-selective doping holds promise for optimizing the electronic properties of conjugated polymers. This approach has been observed on a selection of polymer hosts and dopants, but it is unclear...

Is #SAM really a 'SAM'? Our paper @nanotechie dives into why not all 'SAMs' ensure both efficiency and stability in OSCs. We reveal light-induced degradation in #2PACz. Is your favorite SAM failing your cells? @KAUST_PSE 👉onlinelibrary.wiley.com/doi/… #SolarCells #InterfaceEngineering

The Role of Self‐Assembled Monolayers in the Performance‐Stability Trade‐Off in Organic Solar Cells

This study reveals that spin-coated films of SAM molecules (2PACz and analogs) do not conform to the common assumption of forming monolayers. Compared to PEDOT:PSS, SAM-based devices show significa...

PAPER ALERT!💡 Check out our recent work on the ionic-electronic transport properties of Sn-based perovskites. We found that the influence of Sn vacancies extends beyond the optoelectronic properties. Great effort from @Luis5_4 and team. pubs.rsc.org/en/content/arti…

Deciphering the interplay between tin vacancies and free carriers in the ion transport of tin-based...

Mixed ionic-electronic conduction is a prevalent phenomenon in metal halide perovskites, having a critical impact in multiple optoelectronic applications. In Sn-based halide perovskites, their higher...

⚡️Reverse bias instability is a major challenge for PV modules in the field. In our latest work @ACSEnergyLett, we tackle this issue in narrow-bandgap Sn-Pb perovskite solar cells by using Cr/Cu top contacts @KAUST_OMEGALab #OpenAccess #ACSEditorsChoice pubs.acs.org/doi/10.1021/acs…

We are excited to share our latest work on organic solar cell (OSC) stability. Utilizing a side-chain-stable polymer donor enables retention of over 90% of the initial PCE during seven months of outdoor testing under the hot Saudi climate. rdcu.be/eeE2M

Our findings show that for most polymer donor-based devices, photo-stability plays a more critical role than thermal stability in determining outdoor device performance.
