Summary: In this study, a p-conjugated polymer PBDB-T is used to improve the stability of semi-transparent perovskite solar cells (ST-PSCs). The incorporation of the polymer forms a polymer composite hole transport layer (HTL) with Spiro-OMeTAD, enhancing the stability of the perovskite/HTL interface and passivating the interfacial defects. The ST-PSCs achieved a champion efficiency of 13.71% and an average visible light transmittance of 36.04%, resulting in a high light utilization efficiency of 4.94%. The encapsulated device maintained 84% of the initial efficiency after 751 hours of continuous one-sun illumination, while the unencapsulated device maintained 80% of the initial efficiency after more than 1250 hours of continuous one-sun illumination.

Summary: Conventional semi-transparent perovskite solar cells generally have lower performance and stability compared to opaque PSCs. This study reveals that lithium ions from a doped hole-transport layer can diffuse into the buffer layer, leading to reduced efficiency and accelerated degradation of semi-transparent PSCs. However, by modifying the surface of the hole-transport layer, this undesired ion diffusion can be avoided, resulting in ST-PSCs with record efficiency and improved stability.

Summary: The effects and mechanism of sputtering damage and poor conductivity of sputtered indium tin oxide (ITO) on perovskite solar cells were investigated in this study. The deposition of tin oxide (SnO2) on non-reactive C-60 resulted in island growth of SnO2 film, leading to large dark current in solar cells. However, this phenomenon was inhibited by decorating C-60 surface with WO3 thin film. By optimizing the buffer layer and electrodes, the fill factor (FF) and power conversion efficiency (PCE) of the semi-transparent solar cells (ST-PSCs) were improved. These findings provide new strategies for damage reduction and performance improvement of ST-PSCs.

Summary: Mixed halide perovskites are promising for high-efficiency perovskite solar cells (PSCs) and tandem solar cells. However, they face challenges of microstrain and phase segregation, resulting in non-radiative recombinations and energy losses. In this study, a dual chloride additive strategy was employed to mitigate these issues. The resulting perovskite films exhibited reduced microstrain and defects, and inhibited iodide ion migration. PSCs with dual chloride additive achieved an efficiency of 22.94% and demonstrated improved stability compared to pristine and single additive PSCs.

Summary: 2D/3D perovskite heterojunctions show promise in improving the efficiency and stability of perovskite solar cells (PSCs). However, challenges still exist in developing high-quality 2D/3D heterojunctions, such as controlling the perovskite phase and poor performance in inverted devices, limiting their commercialization. This paper summarizes the latest research progress and critical factors in modulating PSCs with 2D/3D heterojunctions, highlighting the advantages of constructing these heterojunctions and discussing the problems and solutions of using low-dimensional perovskites as passivation layers. The prospects of utilizing 2D/3D perovskite heterojunctions in passivation strategies to further improve the photovoltaic performance of PSCs in the future are also presented.
