Does lead iodide affect the performance of perovskite solar cells?

It is widely believed that excess/residual lead iodide (PbI 2) can affect the performance of perovskite solar cells . Moderate PbI 2 can enhance efficiency by passivating defects, while extremely active PbI 2 leads to non-negligible hysteresis effects and reduces device stability.

How effective are lead halide perovskite solar cells?

Over the past few years, the performance of lead halide perovskite solar cells has rapidly surged. Since the first demonstration of good performance with these materials, (1,2) the power conversion efficiency increased from 12% to 22.1% (3) in a span of just three years.

Are perovskite solar cells safe?

Despite notable advantages and power conversion efficiency achieved by perovskite solar cells (PSCs), they could not hit the market commercially as perovskite solar cells are bottlenecked by the toxicity issue caused by the metal lead. Lead has proven toxicity issues that can harm human beings and the ecological system to a significant extent.

Are antimony-based perovskites a good substitute for lead-based solar cells?

In precise, Cs 3 Sb 2 I 9 is a promising substitute for lead-based perovskites with their enhanced photovoltaic performance . But there are also a few challenges associated with antimony-based perovskites which need to be confronted to produce an efficient perovskite solar cell.

Are lead halide perovskites toxic?

Despite their appealing performance, using lead-halide perovskites in indoor applications poses toxicity issues because there would be no other protection between the human end-user and the lead contained within the perovskite device except the encapsulating layer.

Do lead iodide perovskites have a bandgap?

Recent results suggest that lead iodide perovskites may have both a direct and indirect bandgap, (16,17) a consequence of the Rashba effect. (18,19) This could influence the shape of the band-edge absorption.
