Ideal Deposition Roots For SALD For Perovskite Solar Cells

Ideal Deposition makes production equipment for perovskite solar cells (PSC) with an annual capacity of 300 atomic layer deposition (ALD) units/year. Speaking on Day 4 of the 4-day TaiyangNews High Efficiency Solar Technologies 2024 conference, Ideal Deposition’s Process Technology Manager Dr. Jun Wang presented the company’s SALD or Spatial ALD technology.

ALD is well-established and widely acknowledged as a deposition technique for solar cell layers. However, Wang said that ALD’s long production process approach limits its power. SALD, or spatial ALD, has a shorter process time, she explained, adding that it is suitable for large-area deposition and mass production. It increases the deposition rate compared to ALD.  

Ideal Deposition developed its deposition solutions for perovskite solar cells based on SALD, in which the 2 half reactions are not separated by time but by space, as the substrates move laterally absorbing different precursors separated by inert gas curtains. Wang claimed there is growing interest in the technology in the PSC market.
