About Which silicon wafer is best for solar power generation

When the four kinds of silicon wafers were used to generate the same amount of electricity for photovoltaic modules, the ECER-135 of S-P-Si wafer, S-S-Si wafer and M-S-Si wafer were 3.3, 4.5 and 2.8 times of that of M-P-Si wafer respectively.

Crystalline silicon (c-Si) solar cells have been the mainstay of green and renewable energy 3, accounting for 3.6% of global electricity generation and becoming the most cost-effective.

Here, authors present a thin silicon structure with reinforced ring to prepare free-standing 4.7-μm 4-inch silicon wafers, achieving efficiency of 20.33% for 28-μm solar cells.

In silicon wafer-based solar cells, the front side is engineered with two optical functions: texturisation through a dry or wet etch process and antireflective coating. Alkaline etching of crystalline silicon reveals a pyramidal geometry in the micron range dimension.

Silicon wafer-based solar cells dominate commercial solar cell manufacture, accounting for about 86% of the terrestrial solar cell industry. For monocrystalline and polycrystalline silicon solar cells, the commercial module efficiency is 21.5% and 16.2% [10–12].
