We discuss the major challenges in silicon ingot production for solar applications, particularly optimizing production yield, reducing costs, and improving efficiency to meet the continued high demand for solar cells. We review solar cell technology developments in recent years and the new trends.
In order to evaluate this on a global scale, we examine the global efficiency of the 2T Si-based tandem solar cells under three scenarios: where the silicon bottom cell has 2/3 and 1/3 of the optimal thickness for that particular location and a scenario where its thickness is fixed at 160 μm (industry standard) for the entire world.

Performance diverges for different cell types. The variation for silicon cells is equivalent to ~20 °C of temperature variation. A limitation in the performance rating of solar cells and modules is that they are evaluated using a single value for the solar spectrum: AM1.5.
For the silicon solar cell (single-junction or the bottom cell of tandem cell), we implemented one-dimensional semiconductor modeling, whereas for the top cell, we based our calculations on the Shockley-Queisser''s approach. 39 Current matching was further used to obtain the overall J-V curve of the two-terminal tandem cell.

In this chapter, we explain the most important properties of every material that serve as indispensible part of Si-based solar cell to contribute to high efficiency, and shed a light on some of the most important points and subjects raised in individual contributions, and also give a brief survey of relevant research efforts in a broader context.
Improving the efficiency of silicon-based solar cells beyond the 29% limit requires the use of tandem structures, which potentially have a much higher (~40%) efficiency limit. Both perovskite/silicon and III-V/silicon multijunctions are of great interest in this respect.
Turning to the results, the conversion efficiency of c-Si solar cells has a maximum at a given value of the thickness, which is in the range 10–80 µm for typical parameters of non-wafer-based silicon.
