In hopes of one day replacing silicon-based photovoltaic solar cells, which are relatively expensive and require a lot of energy to make, scientists have turned to hybrid organic-inorganic lead halide perovskites
When one type of an oxide structure called perovskite is exposed to both water vapor and streams of electrons, it exhibited behavior that researchers had never anticipated.
Perovskite compounds commonly are comprised of a hybrid organic-inorganic lead or tin halide-based material and have been pursued as potential materials for solar cells for several years.
Perovskite materials have shown great promise for use in next-generation solar cells, light-emitting devices (LEDs), sensors, and other applications, but their instability remains a critical limitation.
Tiny defects in perovskite’s crystalline structure can hamper the conversion of light into electricity in a solar cell, but “what we’re finding is that there are some defects that can be healed under light
A new study has found both the cause and a solution for the pesky tendency of perovskite solar cells to degrade in sunlight, a research breakthrough potentially removing one roadblock to commercialization for this promising technology.
