Although metal halide perovskites are increasingly popular for the next generation of efficient photovoltaic devices, the inevitable defects from the preparation process have become the notorious barrier to further improvement of performance, which increases non-radiative recombination and lowers the power conversion efficiency of solar cells.
The surface passivation of the perovskite layer has become one of the most critical methods to address these challenges. This review introduced defects and their influence on the cell''s performance in different aspects (the carrier …

The amount of solar energy incident on the earth surface every second (1650 TW) is higher than the combined power consumption by using oil, fossil fuel, and other sources of energy by the entire world community (< 20 TW) in 2005. The solar photovoltaic power generation are ever increasing in capacity, yet at a lower scale.
Following the invention of the PECVD method by Stirling and Swann in 1965 [11], this technique was soon used for electronic devices and, in the mid-1970s, for photovoltaic (PV) devices (amorphous silicon solar cells [12]) 1981, Hezel and Schörner [1] transferred the fabrication of SiN by PECVD from the microelectronics industry to the crystalline silicon PV …

Low-cost double-sided passivation of perovskite solar cells improved perovskite surface and PV performance by 11.7 %. • Biphenyl-4,4 -dicarboxylic acid used for the first time to passivate perovskite solar cells. • Passivation created a barrier to migrating ions, reducing intrinsic degradation and J-V hysteresis. •
Consequently, the device with surface passivation enhances the power conversion efficiency (PCE) and long-term ambient stability of PSCs by maximizing the c-TiO2 ETL electrical characteristics. It is also discovered that the passivated c-TiO2 layer has increased hydrophobicity and reduced the RMS surface roughness from 28.8 to 27.3 nm.
Right panels in Figure 2a and b show a cross-sectional image of CQDs in stable final configuration. Initially, for both passivation we observe O2 embedding into the top surface monolayer, resulting in the coordination of O2 by 2-3 cations. However, the O2 molecule remains labile and can diffuse across the surface. In the case of PbI2 passivation,
