In the current study, we aim to limit the power dissipation in amorphous silicon solar cells by enhancing the cell absorbance at different incident angles. The current improvement is justified by adding the single-period of ternary 1D photonic crystal with texturing on the top surface, which acts as an anti-reflecting coating. The texturing shape gives the photons at …
Single crystalline silicon solar cells have demonstrated high-energy conversion efficiencies up to 24.7% in a laboratory environment. One of the recent trends in high-efficiency silicon solar cells is to fabricate these cells on different silicon substrates. Some silicon wafer suppliers are also involved in such development.
Therefore, the optical properties of silicon are isotropic. At room temperature, photons greater than ~1.05 eV are absorbed; according to the Shockley-Queisser limit the maximum possible efficiency of a single-junction silicon solar cell is ~31.5%.
On single crystal silicon solar cells, this texturing results in the formation of pyramidal structures that are randomly positioned, but of the same orientation. The size of these pyramids is 2–8 μm, which is considerably greater than the wavelength of light used in ellipsometry experiments, resulting in significant light scatter.
One of the recent trends in high-efficiency silicon solar cells is to fabricate these cells on different silicon substrates. Some silicon wafer suppliers are also involved in such development. Another recent trend is the increased production of high-efficiency silicon cells, some of them with low-cost structures.
Part of the book series: Springer Series in Optical Sciences ( (SSOS,volume 212)) Most solar cells are fabricated from crystalline or semicrystalline silicon since they are relatively inexpensive starting materials and the resulting solar cells are very efficient.
However, many high-efficiency silicon solar cells have a very rough surface that has been textured using a preferential etch. On single crystal silicon solar cells, this texturing results in the formation of pyramidal structures that are randomly positioned, but of the same orientation.
