Inorganic hole transport layers in inverted perovskite solar cells: A review

Hybrid interfacial ETL engineering using PCBM-SnS2 for High-Performance p-i-n structured planar perovskite solar cells

The rapid and continuous progress made in perovskite solar cell (PSC) technology has drawn considerable attention from the photovoltaic research community, and the application of perovskites in other electronic devices (such as photodetectors, light-emitting diodes, and batteries) has become imminent. Because of the diversity in device configurations, optimization of film deposition, and exploration of material systems, the power conversion efficiency (PCE) of PSCs has been certified to be as high as 25.2%, making this type of solar cells the fastest advancing technology until now. As demonstrated by researchers worldwide, controlling the morphology and defects in perovskite films is essential for attaining high-performance PSCs. In this regard, interface engineering has proven to be a very efficient way to address these issues, obtaining better charge collection efficiency, and reducing recombination losses. In this review, the interfacial modification between perovskite films and charge-transport layers (CTLs) as well as CTLs and electrodes of PSCs has been widely summarized. Grain boundary (GB) engineering and stress engineering are also included since they are closely related to the improvement in device performance and stability.

Hybrid organic/inorganic organometal halide perovskite solar cells (PSCs) have been attracting enormous research interest. However, their performance improvement and engineering at the molecular level remain challenging for the inverted structures. Surface traps present in semiconductor films critically influence ultimate photovoltaic behaviors. A solution-processable and stable cathode buffer layer that can passivate surface traps is thus of great importance for the application of PSCs. Here, we successfully fabricated high performance and stable inverted planar PSCs by employing calcium acetylacetonate (Ca(acac)2), a molecular modulator, as the cathode interfacial layer (CIL). The average power conversion efficiencies of PSCs based on different perovskite photoactive layers were improved. Strikingly, FA0.85MA0.15Pb(I0.85Br0.15)3-based and MAPbI3-based PSC devices were found to have champion power conversion efficiencies of 20.15% and 18.23%, respectively. Importantly, Ca(acac)2-modified PSCs also have high stability. Their power conversion efficiencies decreased by only 15% after 30 days of storage and they show much suppressed hysteresis compared with the control devices (without interfacial modification).
