The PHOTOSINT project is driving innovation in perovskite solar cells (PSCs) for sustainable energy, achieving preliminary success in encapsulation methods that helped retain over 80% of the initial PCE in high-humidity conditions closer to real-world
In the drive for sustainable energy, perovskite solar cells (PSCs) are emerging as a high-potential option for integration into photoelectrocatalytic (PEC) systems. The latest approach by the CSIC team is focused on enhancing the performance and efficiency of PSCs, making them both a cost-effective and efficient choice for sustainable energy needs.
At the heart of the Photosint project is the use of halide perovskites, selected for their strong light absorption and potential to reach high energy conversion efficiencies. Recent achievements include individual PSCs with a power conversion efficiency (PCE) exceeding 18%, coupled with impressive short-circuit current densities (JSC) over 22 mA/cm² and open-circuit voltages (VOC) around 1 V. These figures highlight the progress being made toward creating PSCs capable of delivering reliable and high-performing power sources for PEC applications.
The team also explored various module configurations to expand the application range of PSCs. These designs demonstrated scalability and versatility by achieving a range of output currents—from 3 mA to over 50 mA—and output voltages spanning 1 V to 8 V. This flexibility enables the cells to meet the diverse energy demands of different PEC systems, paving the way for broader adoption and customization.
Tackling Stability Challenges
Despite these advancements, one of the significant challenges PSC technology faces is stability under environmental stressors, such as high humidity and temperature fluctuations. Addressing this, the CSIC team achieved preliminary success in encapsulation methods that helped retain over 80% of the initial PCE in high-humidity conditions. This is a promising step forward for PSCs, moving them closer to real-world applications where durability and longevity are essential.
Stay tuned for further updates on this promising technology as we work towards a more sustainable, energy-efficient future!
