NaHCO3‐induced porous PbI2 enabling efficient and stable perovskite solar cells

Abstract Driven by their many unique features, perovskite solar cells (PSCs) have become one of the most promising candidates in the photovoltaic field. Two‐step preparation of perovskite film is advantageous for its higher stability and reproducibility compared to the one‐step method, which is more suitable for practical application. However, the incomplete conversion of the dense lead iodide (PbI2) layer during the sequential spin‐coating of formamidinium/methylammonium (FA+/MA+) organic amine salts severely affect the performance of PSCs. Herein, sodium bicarbonate (NaHCO3) is used to induce the formation of porous PbI2, which facilitates the penetration of the FA+/MA+ ions and the formation of a perovskite film with high crystallinity and large grain microstructure. Meanwhile, the introduction of Na+ not only improves the energetic alignment of the PSC, but also increases the conductivity via p‐doping. As a result, the optimized NaHCO3‐modified PSC achieves a champion power conversion efficiency of 24.0% with suppressed hysteresis. Moreover, the significant reduction in defect density and ion migration as well as a mild alkaline environment enhance the stability of device. The unencapsulated NaHCO3‐modified PSCs maintain over 90% of their original efficiency upon storage in ambient air (30%–40% relative humidity) for 2160 h. We have demonstrated an ingenious strategy for controlling the quality of perovskite and improving the performance of device by low‐temperature foaming of simple inorganic molecules of NaHCO3

Photocapacitor integrating voltage-adjustable hybrid supercapacitor and silicon solar cell generating a Joule efficiency of 86%

Photocapacitor integrating both energy harvest and storage functions into a single device is a frontier research orientation, which facilitates the efficient and sustainable utilization of green energy. However, the multi-functions in one device and structural complexity of the integrated device, particularly the mismatch between energy harvest and storage units, lead to a relatively large energy loss in the energy storage and output processes. Here, we design a voltage adjustable hybrid supercapacitor (VAHSC) as an energy storage unit of a three-terminal photocapacitor. The VAHSC effectively harmonizes the energy harvest and storage units, resulting in the current, voltage, power, and energy match between both units. The optimal photocapacitor achieves a storage efficiency as high as 98.28% and Joule efficiency of 86.01%, along with excellent charge/discharge cycle stability. The great leap in this efficiency marks a substantial step towards the practical application of solar-charging energy storage integrated devices.GM
