“…Pinholes are formed in the thin oxide layer during the growth or annealing, [31][32][33] play a crucial role in carrier transport through tunnel oxide layer. [34] In practice pinholes formed in the tunnel oxide layer are not uniform, the radii vary in the range 2-40 nm, and density varies in the range 10 5 -10 10 cm À2 . Also, for all the pinholes, poly-Si does not make direct contact with Si substrate rather a very thin oxide layer exists in between.…”

Passivated emitter and rear contact (PERC) on p‐type mono silicon has a roadmap for achieving >24% efficiency. The decrease of the full‐area rear metal contact to partial rear contact (<10%) accounts for the majority of the increase in efficiency of PERC solar cells over Al‐BSF solar cellswhich reached its maximum efficiency around 19.5%. P‐type tunnel oxide passivated contacts (TOPCon) solar cells have achieved further improvement in efficiency ≥25% by completely removing the partial rear metal contact and introducing a thin tunneling oxide layer at the rear. Thus passivating the partial rear and front metal contacts using SiOx/poly‐Si tunnelling layer stacks and an AlOx/SiNx stack on the entire back surface to passivate the remaining areas might lead to further advancements in PERC solar cells. Therefore, by integrating TOPCon and PERC architectures, as originally proposed by Fraunhofer lab, a modified design known as TOPerc solar cell has been studied in depth in this paper. Using 3D Sentaurus TCAD simulation software, a thorough numerical simulation of a p‐TOPerc solar cell has been performed. It is shown that efficiency of 25.2% and 26.0% is obtained for a p‐type wafer of bulk lifetime of 400 μs and 5.0 ms, respectively.

“…Additionally to the above-mentioned problems, Potential-Induced Degradation (PID), Light-Induced Degradation (LID), and general degradation are indeed crucial concerns in the realm of PV technology, especially with the advent of modern advancements like the half-cut Passivated Emitter Rear Cell (PERC) [87,88] or Top Contact (TopCon cells) [89,90]. It may take a long time to detect the PID through traditional data analysis methods, resulting in an undetected energy loss [91].…”

The installed solar capacity in the European Union has expanded rapidly in recent years. The production of these plants is stochastic and highly dependent on the weather. However, many factors should be considered together to estimate the expected output according to the weather forecast so that these new PV plants can operate at maximum capacity. Plants must be operated in coordination with maintenance operations and considering actual energy market prices. Various methods have recently been developed in the literature, ranging from the most impactful artificial-intelligence-based generation estimation methods to various diagnostic and maintenance methods. Moreover, the optimal operational and maintenance strategy usually depends on market regulation, and there are many concerns related to the distribution system operator. This review article aims to summarize and illustrate the challenges of operating and maintaining solar power plants and the economic and technical importance of these problems.
