Westra's materials are also unlocking new performance levels in solar energy technologies. Used as electron transport materials (ETMs) in next-generation photovoltaic devices, our conductive polymers play a critical role in improving both the efficiency and durability of solar cells. In these devices, the interface between active layers is one of the most sensitive and performance-limiting aspects. Poor energy alignment or unstable interfaces often lead to reduced power conversion efficiency and rapid device degradation.
Westra's ETMs address these challenges by providing excellent energy level alignment with typical photoactive materials, enabling more efficient charge extraction and reduced energy losses. At the same time, our materials form stable, high-quality interfaces that prevent unwanted chemical reactions and degradation mechanisms at the critical junctions within the solar cell. This dual benefit, enhanced performance and improved stability, translates directly into higher power output and significantly longer operational lifetimes.
By extending the lifespan of solar modules and improving their efficiency, Westras technology contributes to lowering the levelized cost of electricity from solar installations, making renewable energy more affordable and competitive. In doing so, we are actively supporting the global transition towards cleaner energy systems, helping to meet ambitious climate targets and accelerating the widespread adoption of renewable energy solutions. Our materials are enabling solar technologies to go further, to last longer, perform better, and deliver more sustainable energy to a growing world.
