Intermediate phase is considered an important aspect to deeply understand the crystallization procedure in the growth of high-quality perovskite layers by an anti-solvent technique. However, the moisture influence on the intermediate phase formation is not clear in air conditions as yet. In this work, pure (FA0.2MA1.8)Pb3X8(DMSO·DMF) intermediate phase was obtained in as-prepared perovskite film by spin-coating the precursor of co-solvent (DMSO and DMF) in an ambient air (RH20–30%). Moreover, the appropriate quantity of ethyl acetate (C4H8O2, EA) also controls the formation of pure intermediate phase. The uniform and homogeneous perovskite film was obtained after annealing this intermediate film. Therefore, the best power conversion efficiency (PCE) of perovskite solar cells (PSCs) is 16.24% with an average PCE of 15.53%, of which almost 86% of its initial PCE was preserved after 30 days in air conditions. Besides, the steady-state output efficiency ups to 15.38% under continuous illumination. In addition, the PCE of large area device (100 mm2) reaches 11.11% with a little hysteresis effect. This work would give an orientation for PSCs production at the commercial level, which could lower the cost of fabricating the high efficiency PSCs.

Power conversion efficiency (PCE) of perovskite solar cells increases very rapidly and more than 22% is already achieved. However, some problems still need to be resolved for mass production and commercialization, including reducing production costs and development of large area solar cells. The best PCE is reached by very small active area, mostly below 0.5 cm2 which is mostly produced by spin-coating technique. Moreover, the perovskite precursor materials, mostly lead (II) iodide (PbI2) and hole-transport materials (HTM) Spiro-OMeTAD are expensive material in perovskite solar cells. Therefore, the use of low-cost perovskite precursors and low-cost HTM materials is one way to reduce the whole production costs of perovskite solar cells. Nowadays, many groups have been developed HTM-free perovskite solar cells using carbon-based mesoscopic solar cells for low cost production and large area perovskite solar cells, although the PCE of large area perovskite solar cells is still half than that very small area prepared by spin-coating technique. Here, we report our recent study to fabricate perovskite solar cells using mesoscopic carbon-based structure consisting of glass/ITO/TiO2/ZrO2/perovskite/carbon with active area larger than 1 cm2 by use of simple screen printing technique in ambient air with high humidity. We also synthesize PbI2 as perovskite precursor material from electrodes of used car battery to reduce the cost of solar cells production. Although, the PCE is still much lower than that reported by other groups, however, our study shows that perovskite solar cells from used car battery and with active area more than 1 cm2 can be fabricated in ambient air with high humidity by use of simple screen printing technique.

Materials and processing of transparent electrodes (TEs) are key factors to creating high-performance translucent perovskite solar cells. To date, sputtered indium tin oxide (ITO) has been a general option for a rear TE of translucent solar cells. However, it requires a rather high cost due to vacuum process and also typically causes plasma damage to the underlying layer. Therefore, we introduced TE based on ITO nanoparticles (ITO-NPs) by solution processing in ambient air without any heat treatment. As it reveals insufficient conductivity, Ag nanowires (Ag-NWs) are additionally coated. The ITO-NPs/Ag-NW (0D/1D) bilayer TE exhibits a better figure of merit than sputtered ITO. After constructing CsPbBr3 perovskite solar cells, the device with 0D/1D TE offers similar average visible transmission with the cells with sputtered ITO. More interestingly, the power conversion efficiency of 0D/1D TE device was 5.64%, which outperforms the cell (4.14%) made with sputtered-ITO. These impressive findings could open up a new pathway for the development of low-cost, translucent solar cells with quick processing under ambient air at room temperature.
