Ultra-Stable Perovskite Solar Cells
There’s been a lot of interest in perovskite solar cells (PSCs) lately, and for good reason. Compared to conventional silicon solar cells, PSCs are lightweight, flexible, cheap to produce and easy to manufacture. With rapidly-rising power conversion efficiencies now being realized, the biggest obstacle for PSCs on their path to commercialization is long-term stability.
This challenge is rooted in the volatile nature of organic components contained within perovskites which, when exposed to environmental stimuli like light, heat and electric fields, can lead them to migrate or escape from the perovskite layer. This leads to rapid degradation, which significantly reduces the efficiency, stability, and performance of PSCs.
The BondLynx Advantage
A new study, released in the sustainable energy research journal Joule, demonstrates how PSCs treated with BondLynx can achieve remarkable efficiency and stability, even after 1,000 hours of continuous exposure to environmental stimuli. The results are extraordinary:
- Illumination Stability: After 200 hours of continuous operations under 1 sun illumination (1 KW/m2), untreated control PSCs exhibited a 35% loss in power conversion efficiency. In comparison, BondLynx-treated PSCs showed remarkable stability, retaining nearly 99% of their initial efficiency even after 1,000 hours of continuous illumination.
- Thermal Stability: When exposed to constant heat (60°C), untreated PSCs demonstrated poor thermal stability, losing 27% efficiency after 600 hours of continuous operation. In comparison, BondLynx-treated PSCs maintained nearly 98% efficiency under the same conditions.
- High Efficiency: Overall, BondLynx-treated PSCs achieved a high certified efficiency of over 24% with long operational stability over 1,000 hours.
The reason BondLynx is effective is because it forms chemical covalent bonds with the organic components in PSCs to strongly immobilize them, thereby reducing the losses of efficiency, stability, and performance typically seen in PSCs. With no significant reduction in performance over the course of the study, the stability improvements realized by BondLynx are expected to extend far beyond the 1,000 hour mark.
We look forward to engaging with companies operating in the perovskite solar cell sector to explore what can be achieved. Bring your projects – let’s collaborate!
