Thin silicon wafers used in solar panels have a few advantages over the standard 160 μm wafers.
50 μm wafers substrates could potentially reduce the cost of fabricating solar panels capex by 48%, module cost by 28%, and LCOE by 24%.

UniversityWafer, Inc. and our partners have developed a new process for producing ultra-thin silicon wafers that can be processed with standard semiconductor equipment on flexible substrates. To provide a more flexible substrate for the production of ultra-thin semiconductors, we have started to produce thicker silicon rings to support ultrasonic wafers. We develop new processes for the production of thin-ring silicon with a thickness of less than 1 micrometer (micrometer) and a diameter of only 1 mm.
Scientists have used the following substrate spec to fabricate silicon-based MEMS vibrating mesh nebulizer for inhaled drugs.
100mm Undoped (100) 75um DSP
Scientists use the spec above to fabricate a silicon mesh for atomizing liquid.

Researchers have used the following ultra-thin silicon wafers to fabricate their masks.
I’m looking to use these as physical etch masks for my plasma FIB. I’ve been told 100 um thickness works well, I’m curious to see if thinner gives similar results. As far as other specs, I just need material to get in between the Xe ions and my sample. I’ll take whatever you’ve got.

What are ultra-thin silicon wafers? Wafers with a thickness of 200 micron of thinner use the following for their thinning process mechanical grinding, stress reduction, polishing and etching. Presently and in the future ultra-thin silicon are important building blocks for the manufacture of semiconductor devices. Due to the special mechanical properties of ultra-thin wafer production, the handling of these wafers differs from the conventional one. Due to the rise of taiko wafers, special devices and carriers have the potential to eliminate ultra-thin wafer handling. Advances in ultra-thin wafer technology, manufacturing process, wafer transport and device applications are reviewed here.
Ultra-thin wafers have wide applications in semiconductor device manufacturing and will have long-term implications for the semiconductor industry.
Below are just some of the thickness wafers that we have in stock:
Other wafer thicknesses are available.
Climate change (formally referred to as global warming) is the greatest problem earth faces today. Scientists are urgently researching how to transition to a carbon-neutral energy system using the sun’s solar rays. Using current technologies, scientists have proven that the thinner the solar panel the greater the overall efficiency of production and solar capture. UniversityWafer, Inc. has assisted scientists in their quest for thin-silicon used to fabricate solar modules.
A research scientist requested the following quote:
UniversityWafer, Inc. Quoted:
156mm x 156mm 150 ±10um N/Ph  ±3° Lapped 1-7 ohm-cm PSQ (Pseudo-Square), PV, Coin-roll packed in a group of 74 wafers (smaller Qty at higher price)
Researcher followed up:
UniversityWafer, Inc. Responded:
Q1. what is PSQ (Pseudo-Square), PV, Coin-roll packed? - I don't understand this because I'm looking for diamond wire sawn (DWS) wafers (the wafers we get from the ingot before polishing etc)
A1. PSQ means "pseudo-square" and the acronym describes the wafer's shape, which is square with the corners cut-off (please see the picture). The wafers are DWS but also lapped after slicing to remove the damage layer occurred after the sawing.
Q2. Do you have p-type? - because I'm little more interested in single crystal p-type DWS silicon wafers (Though you can still send the quotation for n-type in case p-type is not available)
A2. No, we do not
Q3. I need one box of silicon wafers i.e. 25 pieces in quantity.
A3. These wafers are coin roll packed. We offer 25 pieces of item #7201 for $ /wafer.
Q4. Also, will it be possible for you to share me a picture of the wafer you mentioned above (if it's possible)?
A4. Here is a photo:
