Alzchem: Innovative Guanidine Salts for the Next Generation of Solar Cells

Alzchem supports the development and optimization of perovskite solar cells with high-quality guanidine salts such as guanidine thiocyanate and guanidine hydrochloride. These specialty products are manufactured with high purity and quality and can be crucial for increasing the efficiency and longevity of modern solar cells. More than 50 scientific publications demonstrate that the use of these additives can achieve an efficiency gain of up to 5.5% as well as significantly improved stability in laboratory settings. The extended durability is achieved through surface sealing, defect repair, reduced moisture penetration, more stable crystal structures, and limitation of charge losses. The advantages of Alzchem’s guanidine salts are their low metal content, minimal impurities, and high flexibility in the formulation of these chemicals.  

Guanidine Salts as an Additional Driver for the Renewable Energy Transition 

Perovskite solar cells are currently at the threshold from applied research to commercialization and are considered a potentially disruptive technology compared to conventional, silicon-based photovoltaic systems. While conventional silicon cells are limited in their maximum efficiency, perovskite solar cells achieve significantly higher efficiencies—in the upper twenties or mid-thirties percent range, both in exclusive perovskite systems and in perovskite/silicon tandem cells. Their high flexibility and transparency enable numerous specialized applications, such as coating windows, displays, windshields, or price tags. Additionally, perovskite solutions can be produced more cost-effectively than silicon solar cells.  

Ecological and Economic Advantages of Perovskite Solar Cells 

Perovskite solar cells have gained significant attention worldwide, as reflected in increasing investments from research institutions and companies. Their material properties and the ability to be printed on flexible substrates pave the way for innovative design concepts in energy generation. For example, facades, exterior walls, or portable devices can be efficiently supplied with energy, opening new perspectives for integrating renewable energies into everyday life. Resource-saving and energy-efficient manufacturing offers ecological and economic advantages over conventional technologies. Nevertheless, improving long-term stability and reliability remains a central challenge, requiring interdisciplinary approaches from materials science, chemistry, and engineering. Collaboration between industry partners like Alzchem and academic research institutions promotes rapid technology transfer and ensures that innovations reach the market promptly.
