Crystalline silicon solar cells make use of mono- and multicrystalline silicon wafers wire-cut from ingots and cast silicon blocks. An alternative to standard silicon wafer technology is constituted by amorphous or nanocrystalline silicon thin films, which will be described in the next subsection.
Silicon-based solar cells occupy an absolutely dominant position in the solar cell market, accounting for more than 90% of the market share. With the advantages of abundant raw materials, mature production technology, long service life, and high efficiency, crystalline silicon solar cells are the most promising solar cells in the short term [169] .
High carrier recombination loss at the metal and silicon contact regions is one of the dominant factors constraining the power conversion efficiency (PCE) of crystalline silicon (c-Si) solar cells. Metal compound-based carrier-selective contacts are being intensively developed to address this issue. In this work, we present a high-performance electron-selective

To further increase the conversion efficiency of crystalline silicon (c-Si) solar cells, it is vital to reduce the recombination losses associated with the contacts. Therefore, a contact structure that simultaneously passivates the c-Si surface while selectively extracting only one type of charge carrier (i.e., either electrons or holes) is desired. Realizing such passivating contacts in c-Si
Because of its earth-abundant element, a suitable band gap of 1.12 eV, high purity, high minority carrier lifetime, very low grain boundary defects, and easy control of resistivity, crystalline silicon (c-Si) is widely used for solar cells and accounts for more than 90% of the current photovoltaic market [1, 4].

In particular, the PERC solar cell concept (Passivated Emitter Rear Cell) has shown a pronounced potential for increasing performance with only moderate changes in the cell production process. The advantage of this cell concept is that it has an "evolutionary" character, whereby the existing process plants for standard solar cells are preserved, and only small

The effect of reverse current on reliability of crystalline silicon solar modules was investigated. Based on the experiments, the relation between reverse current and hot-spot protection was discussed. In avoid of the formation of hot spots, the reverse current should be smaller than 1.5 A for 125mm×125mm mono-crystalline silicon solar cells when the bias voltage is at -12V.

Crystalline silicon solar cells are made with wafers that are cut out from monocrystalline or multicrystalline ingots after some processing steps. Ingot growth requires very pure silicon feedstock, although the purity level is lower than that needed for electronic devices.

Commercially, the efficiency for mono-crystalline silicon solar cells is in the range of 16–18% (Outlook, 2018). Together with multi-crystalline cells, crystalline silicon-based cells are used in the largest quantity for standard module production, representing about 90% of the world's total PV cell production in 2008 (Outlook, 2018).
The first generation of the solar cells, also called the crystalline silicon generation, reported by the International Renewable Energy Agency or IRENA has reached market maturity years ago . It consists of single-crystalline, also called mono, as well as multicrystalline, also called poly, silicon solar cells.
The device structure of a silicon solar cell is based on the concept of a p-n junction, for which dopant atoms such as phosphorus and boron are introduced into intrinsic silicon for preparing n- or p-type silicon, respectively. A simplified schematic cross-section of a commercial mono-crystalline silicon solar cell is shown in Fig. 2.
With this design Kaneka Corporation has surpassed the world record by 0.7 % to a new world record of world’s highest conversion efficiency of 26.33% in a practical size (180 cm2) crystalline silicon solar cell.The theoretical efficiency limit of this type of cell as calculated is 29%.The difference of 2.7 % is attributed to a number of losses.
In solar cell fabrication, crystalline silicon is either referred to as the multicrystalline silicon (multi-Si) or monocrystalline silicon (mono-Si) [70–72]. The multi-Si is further categorized as the polycrystalline silicon (poly-Si) or the semi-crystalline silicon, consisting of small and multiple crystallites.
