Since silicon wafers undergo a high temperature processing during phosphorous diffusion prior to co-firing process, no considerable impact on bulk of silicon is expected. Therefore, recombination and resistive losses associated with the surfaces of silicon solar cells induced during co-firing process determines the magnitude of the FF.

If the photon energy is too small, the photons pass unimpeded through the silicon crystal and the energy of the photon is lost for the solar cell. This happens because photons with lower energy cannot produce electron-hole pairs. For such photons, the semiconductor is virtually transparent.
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.

The intrinsic loss processes of a crystalline silicon (c-Si) solar cell at different concentration ratios (n = 1 and 5) with the bandgap of 1.1246 eV at 298.15 K (25 °C) are presented in Table 1, under an AM1.5 solar illumination (PIncident = 1000.37 W/m 2, calculated by the integral of PFD (E)).
The losses of a solar cell can be divided into three categories: 1. 2. 3. Ohmic losses. In this chapter, we cover the basics of optical losses and recombination losses. Ohmic losses occur mainly when individual solar cells are assembled into entire modules; they will find application in Chaps. 9 and 10.
Among the loss processes, the below E g loss and the thermalization loss play dominant roles in energy loss processes. These two kinds of loss processes are unavoidable in traditional single bandgap solar cells for the mismatch between the broad incident solar spectrum and the single-bandgap absorption of a cell [10, 12].
Silicon solar cells have a limited ability to capture low-energy photons, which limits their efficiency, especially in low-light conditions. Moreover, the practical limits in obtaining maximum efficiency are restricted by many factors including different types of recombinations and losses (Shah et al., 2004).
