New! Self-Assembled Monolayer (SAM)

Chao et al. demonstrated that Py3 (LT-S9998) has the potential to improve PSC performance and stability compared to conventional 2PACz, allowing an inverted PSC by using Py3 to achieve the PCE of 26.1% and showing predicted T90 about 7,462hrs under 1-sun light soaking at 55°C.

New! Perovskite Precursors

Chen et al. used oleylammonium iodide (OAmI, LT-S9539) to stabilize the desired crystal nuclei and vacuum quenching to control surface tension. Perovskite-silicon tandem solar cells with a 25 cm2 active area achieved the PCE of 29.4% and retained 90% of that efficiency after 800 hours at 50°C. The stable power output of champion tandem device can even achieve 32.41%. Science, 385 (2024) p554
