What are the primary limitations of existing ETL and HTL materials in perovskite solar cells?
Maryam Bari discusses the challenges associated with existing materials used for Electron Transport Layers (ETL) and Hole Transport Layers (HTL) in perovskite solar cells. Traditional metal oxides, for instance, require high-temperature sintering (around 400°C) to crystallize and function effectively, which is energy-intensive and potentially incompatible with flexible substrates.
Organic semiconducting materials offer good performance but currently lack scalability and cost-effectiveness for large-scale production. Furthermore, the use of toxic solvents in some organic material processing poses environmental concerns.

How does the nanoparticle size distribution of Pina Creation's zinc oxide nano inks contribute to their performance in solar cells?
How does the nanoparticle size distribution of Pina Creation's zinc oxide nano inks contribute to their performance in solar cells?
Maryam Bari presents technical data showcasing the characteristics of Pina Creation's nano inks. Dynamic Light Scattering (DLS) results indicate a nanoparticle size distribution below 10 nanometers for zinc oxide in an isopropyl alcohol (IPA) solvent, which is crucial for achieving uniform and efficient thin films.
Transmission Electron Microscopy (TEM) images of the thin film reveal a crystallized size of around 2 nanometers with high crystallinity. This combination of small particle size and high crystallinity contributes to the enhanced performance of the nano inks in solar cell applications.

* The crystallized size and high crystallinity of the thin film.
* The contribution of these characteristics to solar cell performance.
