This study considers the in situ introduction of a heterojunction capable of tuning energy levels into perovskites, where the energy level difference and the construction of a built-in electric field greatly improve the separation and migration efficiency of photogenerated carriers.
This perspective focuses on recent developments of solution-processed perovskite heterojunctions for solar cells and novel optoelectronic devices, in particular, highlighting the demonstrated and potential advantages of nanocrystal-enabled fabrication strategies.
Recent studies have demonstrated various strategies for using perovskite nanocrystals as a component to fabricate perovskite/perovskite heterojunctions, either with a perovskite thin film or a second nanocrystal layer. Heterojunctions such as these can impart many advantages of both bulk and nanocrystalline perovskite morphologies.
For the perovskite/In-BTC heterojunction films, different quantities of In-BTC nanocrystals were added into the above pristine perovskite precursor solution to form stable suspension with different concentrations of In-BTC for further spin-coating. Afterward, the substrates were heated at 100 °C for 15 min.
In this paper, we present a facile approach to enhance the efficiency and stability of perovskite solar cells (PSCs) by incorporating perovskite with microporous indium-based metal–organic framework [In 12 O (OH) 16 (H 2 O) 5 (btc) 6] n (In-BTC) nanocrystals and forming heterojunction light-harvesting layer.
Heterojunctions are used to tailor the properties of semiconductors in optoelectronic devices, yet for emerging devices composed of metal halide perovskites, fabricating perovskite/perovskite heterojunctions has proved challenging due to solvent incompatibilities and rapid homogenization due to ion migration.
