“…Another factor affecting the performance is the reduction of the surface defect states in NiO x after SAM treatment as these surface states hamper the charge transport process in the device. Figure 4c shows the efficiency chart Vs cost for inverted structured NiO x -based devices, [23,[38][39][40][41][42][43][44][45][46][47][48][49][50][51][52][53][54] (Tables S2 and S3, Supporting Information). Considering the NiO x -based devices involving different modification processes and fabrication procedures, the ODPA-modified device stands in the economical category with decent efficiency.…”

Interfaces in perovskite solar cells (PSCs) play a pivotal role in determining device performance by influencing charge transport and recombination. Understanding the physical processes at these interfaces is essential for achieving high‐power conversion efficiency in PSCs. Particularly, the interfaces involving oxide‐based transport layers are susceptible to defects like dangling bonds, excess oxygen, or oxygen deficiency. To address this issue, the surface of NiOx is passivated using octadecylphosphonic acid (ODPA), resulting in improved charge transport across the perovskite hole transport layer (HTL) interface. This surface treatment has led to the development of hysteresis‐free devices with an impressive ≈13% increase in power conversion efficiency. Computational studies have explored the halide perovskite architecture of ODPA‐treated HTL/Perovskite, aiming to unlock superior photovoltaic performance. The ODPA surface functionalization has demonstrated enhanced device performance, characterized by superior charge exchange capacity. Moreover, higher band‐to‐band recombination in photoluminescence and electroluminescence indicates presence of lower mid‐gap energy states, thereby increasing the effective photogenerated carrier density. These findings are expected to promote the utilization of various phosphonic acid‐based self‐assembly monolayers for surface passivation of oxide‐based transport layers in perovskite solar cells. Ultimately, this research contributes to the realization of efficient halide PSCs by harnessing the favorable architecture of NiOx interfaces.

“…Photovoltaic (PV) technologies are the most promising for clean and renewable energy sources. Recently, crystalline silicon solar cells, [1] perovskite solar cells, [2][3][4][5][6] dyesensitized solar cells, [7][8][9][10] and organic solar cells [11][12][13][14] have made fruitful progress. Crystalline silicon cells (c-Si) are currently the dominating technology with over 95% market share.…”

The main hurdle to the upgradation of photovoltaic industry is the large performance losses that the tunnel oxide passivated contact (TOPCon) and silicon heterojunction (SHJ) cells have during the cutting and separating process for the assembly of shingle solar panels. Here, an organic solution with the passivation effect is prepared in situ by a non‐vacuum spraying process, which effectively compensates the cutting loss caused by laser slicing technology. Both the open‐circuit voltage (Voc) and power conversion efficiency (PCE) are improved. For example, after edge passivation, the Voc and PCE of the 3 × 3 cm2 SHJ (K = 1.186%) cell increase by up to 8 mV and a 1–2% in absolute efficiency, respectively. This passivation‐solution based method can be easily integrated into the current production line and thus solve the issue of cutting loss in separated silicon solar cells. This study provides a new passivation technology to compensate the recombination loss on the edge surface caused by the cutting process in shingle solar panels.
