    Titanium helps perovskite solar cells do a lead detox New Atlas

    Feb 14, 2018 . Over the last few years, perovskite has proven itself to be a promising material for photovoltaic solar cells, but it's not without its problems. Now, a team has found a way to helps solve at least one of those issues, removing toxic lead from the device by substituting in titanium.

    High Tolerance to Iron Contamination in Lead Halide Perovskite .

    Jun 28, 2017 . The relationship between charge carrier lifetime and the tolerance of lead halide perovskite (LHP) solar cells to intrinsic point defects has drawn much attention by helping to explain rapid improvements in device efficiencies. However, little is known about how charge carrier lifetime and solar cell.

    Effect of different lead precursors on perovskite solar cell .

    We present the use of halide (PbCl2) and non halide lead precursors (Pb(OAc)2 (OAc = CH3CH2COO), Pb(NO3)2, Pb(acac)2 (acac = (CH3COCHCOCH3)) and PbCO3) for the preparation of perovskite solar cells. We have confirmed by X ray diffraction the growth of CH3NH3PbI3 in all the analyzed cases, except for.
