Researchers at KAUST, Fraunhofer ISE, and University of Freiburg developed a method using 1,3-diaminopropane dihydroiodide (PDAI) to treat the perovskite surface of perovskite silicon tandem solar cells. The treated solar cells achieved a conversion efficiency of 33.1% and an open-circuit voltage of 2.01 volts. The devices maintained performance at over 40°C for over 1500 hours along the Saudi coast. Why it matters: This innovation overcomes challenges in surface passivation of textured perovskite cells, paving the way for more efficient and stable solar energy solutions suitable for deployment in hot climates.
KAUST researchers have demonstrated that incorporating tetrahydrotriazinium into perovskite/silicon tandem solar cells enhances both performance and stability. The additive increases hydrogen bonds in the perovskite film's crystal structure, improving power conversion efficiency to 33.7% and phase stability during testing under intense conditions. The improved cells showed more stability after 1500 hours of testing, modeling harsh environments. Why it matters: This research offers a pathway to more durable and efficient solar cells suitable for deployment in harsh climates like the Arabian Peninsula, potentially boosting renewable energy adoption in the region.
KAUST scientists developed a new perovskite solar cell design using thin perovskite layers at the top and bottom of the interface. The new design achieves a power conversion efficiency of 25.6%, comparable to silicon solar cells, with only a 5% efficiency loss after 1000 hours of high heat exposure. The key innovation is the use of a specific ligand that interacts effectively with the 3D perovskites for passivation, maintaining purity in the thin layers. Why it matters: This advancement enhances the stability and efficiency of perovskite solar cells, making them a more viable and cost-effective alternative to silicon, especially for countries like Saudi Arabia aiming to increase renewable energy reliance.
