Perovskite semiconductors are an thrilling new materials to be used in photo voltaic cells. They’re extraordinarily skinny and versatile, simple and cheap to fabricate, and extremely environment friendly. Nonetheless, two hurdles should be overcome earlier than perovskite photo voltaic cells could be marketed on a big scale: firstly, they don’t seem to be but secure over a long time, and secondly, essentially the most highly effective perovskite supplies comprise lead.
An fascinating, non-toxic different being investigated at HZB is tin perovskite photo voltaic cells, that are doubtlessly extra secure than their lead-containing counterparts.
Due to their particular electro-optical properties, they’re significantly properly suited to tandem and triple photo voltaic cells. Nonetheless, tin perovskite photo voltaic cells are nonetheless a way from attaining the excessive efficiencies of lead-based perovskites.
SAMs in tin perovskites
In present tin perovskite photo voltaic cells, the bottom contact layer is produced utilizing PEDOT:PSS. This isn’t solely a cumbersome course of, but it surely additionally leads to losses. Nonetheless, in lead perovskites, the PEDOT:PSS layer could be changed with a extra elegant resolution: self-organized…
