Systematic evaluation of the biotoxicity of Pb-based perovskite materials and perovskite solar cells

“…In recent years, Pb-based perovskite materials have been widely used in solar cells, light-emitting diodes (LEDs), photoelectric detectors, and so on. [1][2][3][4][5] Among them, perovskite solar cells (PSCs) are drawing great interest owing to the impressive advantages of perovskite materials, such as their large absorption coefficient, long diffusion length of charges, high carrier mobility, and low exciton binding energy. [6][7][8][9] Compared to Pbbased PSCs, these PSCs without Pb, which supersede Pb with Sn, Bi, Ge, Sb, and Cu, [10][11][12][13] oen show a lower activation energy of formation and undergo faster crystallization, resulting in the poor morphology of perovskite lms and awful photovoltaic performance.…”

Insight into the interface engineering between methylammonium lead halide perovskites and gallium oxide: a first-principles approach

“…To date, the enhanced interfacial properties of MAPbI 3 /Ga 2 O 3 and MAPbCl 3 /Ga 2 O 3 have already been explored by experimental studies. [21][22][23][24][25][26][27][28][29][30][31] The underlying reasons behind the enhanced interfacial properties of perovskite/Ga 2 O 3 systems remain elusive, yet understanding them could offer valuable insights into applying interface engineering for achieving high-performance perovskite-based photovoltaic and optoelectronic devices. [32][33][34][35][36][37] Consequently, there is growing interest in conducting extensive theoretical studies on their interface engineering.…”
