How efficient are silicon wafer-based solar cells?

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].

Will thin-film solar cells displace solar cells based on silicon wafers?

Since the inception of the solar industry in the 1960s, it has been predicted that thin-film solar cells will eventually displace solar cells based on silicon wafers.

Will silicon wafer-based solar cells be eclipsed?

The forecasted eclipse of silicon wafer-based solar cells has not yet occurred, as presently about 90% or more of commercial solar cell products are still bulk silicon devices made from silicon cast ingots, pulled single-crystal boules, or ribbon/sheet.

What is the process flow of a crystalline silicon solar cell line?

Schematic process flow for an industrial crystalline silicon solar cell line. 1. The entrance interface is the wafer in a stack. As a first step the wafers are typically inspected for microcracks using infrared transmission.

How to test the mechanical strength of photovoltaic silicon wafers?

And additional machining processes is required to make samples, which generate non-original defects and further affect the fracture strength. So far, there is no standard test method for evaluating the mechanical strength of silicon wafers, because of a large aspect ratio of photovoltaic silicon wafers.

What is a wet process in silicon solar cells?

The second case is wet process. In the preparation process of silicon solar cells, wet process is a necessary, such as anisotropic etching of silicon to form random pyramids, standard Radio Corporation of America (RCA) cleaning and simplest cleaning with deionized water.
