Fig. 2: Comparison of lead leakage impact in pristine PSCs, HPMCP-modified PSCs and PDMS-modified PSCs.
From: Green encapsulants boost stability and sustainability in inverted perovskite solar cells
a The schematic illustrations of plant and cell testing methods. b The cell survival rate with or without the immersion of HPMCP/PDMS modified perovskite films. c MTT assay for quantitative determination of cell number. The impact of blank, control, PDMS and HPMCP groups on the cell growth performance. Green represents live cells, and red represents dead cells. All scale bars are 100 μm. d The lead release rate of the soil at different time with different PSCs buried. e The sprouting rate of plants at different time with/without different PSCs buried. f Indicators for measuring plant metabolism in blank plants and those grown with PDMS-modified and HPMCP-modified PSCs. g The Pb content in the plants with/without different PSCs buried. The error bars in (b), (d), (g) represent the standard deviation for three samples.
