Abstract

The present invention is a highly stable perovskite solar cell modified based on maleimido undecanoic acid and a preparation method thereof. The structure of the device is, from bottom to top, a metal counter electrode, a hole transport layer, an active layer, an electron transport layer and a substrate; the active layer is a perovskite active layer containing maleimide undecanoic acid. layer; during the preparation process, by adding maleimide undecanoic acid into the perovskite precursor, a ‑COOH functional group containing a long alkyl chain was introduced as a passivation agent. During thermal annealing, the long alkyl The chains are excluded from the perovskite surface to form a hydrophobic passivation layer, which inhibits the non-radiative recombination of charge carriers while significantly improving the device's resistance to humidity and improving the device's efficiency and stability. The present invention has important strategic significance for the accelerated commercialization of perovskite solar cells.

Description

technical field [0001] The invention belongs to the field of novel photovoltaic solar cells, in particular to a highly stable perovskite solar cell modified based on maleimide undecanoic acid and a preparation method thereof. Background technique [0002] With the world's population growth, industrial development, and the accelerated pace of cities, people's demand for chemical energy continues to increase, resulting in increasingly severe energy crisis and environmental problems. Therefore, the need for a clean and renewable energy source to alleviate the energy and environmental crisis is imminent. Among the existing renewable energy sources, developing solar energy to alleviate this problem is a very feasible solution. Organic-inorganic hybrid halide perovskite light-absorbing materials have high optical absorption coefficient, high carrier mobility, high carrier lifetime, bidirectional transport carrier characteristics, high absorption spectral range, low The advantages...
