EQUIPMENT MODEL
ET-V8000/15000 · Batch monocrystalline wafer texturing machine
Robotechnik Intelligent Technology Co., Ltd. ↗The ET-V8000/15000 textures and cleans monocrystalline wafers in alkaline baths for PERC and TOPCon cells. RoboTechnik picked the wetted materials and the way robots are assigned so that chemicals carry over less between tanks. Tie any capacity in the offer to your wafer format and bath configuration.
Covers the ET-V8000/15000 family for PERC and TOPCon. HJT lines use a separate ET-V8000 entry in the same catalogue.

START WITH YOUR PRODUCTION TASK
Ask which variant gives the textured surface your wafers need. Have first-pass process quality and breakage for your format confirmed in writing, apart from the nominal wafer rate.

ET-V8000/15000 figures and what to ask
| Catalogue figure | What it covers | Ask for in the offer |
|---|---|---|
| 8,000–15,000 wafers/hour | Capacity range for the model family. | The variant, wafer format, bath sequence and a sustained run. |
| Availability above 98% | Listed uptime for the machine. | How availability is measured and over what period. |
| M10 breakage below 0.01% | RoboTechnik's figure for M10 wafers. | How breakage is counted, the sample size and test conditions. |
| M12 breakage below 0.02% | A separate figure for M12 wafers. | A matching run on M12 material, reported on its own. |
| PERC and TOPCon alkaline texturing | The process route the machine serves. | Your incoming wafer condition and the surface you need. |

Set the texturing and cleaning scope
Describe your wafers
Send dimensions, thickness and incoming condition, plus the cell process they feed.
List the bath steps
Ask RoboTechnik to name every texturing, cleaning, rinse, dry and transfer step in the actual offer.
Agree the carry-over check
RoboTechnik credits its wetted materials and robot allocation with limiting cross-contamination. Ask how that will be shown on your process.
Define how output is counted
Fix surface and cleanliness measurements, how broken wafers are counted and what a first-pass good wafer is before the trial starts.
03 · PVYard procurement analysis
Wafer rate and breakage sit apart from texture quality
A tool can move wafers at its rated speed and still miss the surface your next process needs. Set the texture criteria with your process engineers and ask for results tied to your wafers and the offered bath route. Breakage figures and surface measurements answer different questions, so request both. The textured wafers go next to the diffusion furnace, so involve that step's engineers when you set the criteria.
Ask RoboTechnik for the chemical, exhaust, utility and maintenance documents that match the configured machine. Bath chemistry and settings come from that package and your own process team. If the plant runs several wafer formats, ask how recipes and carriers change over and watch the change in the trial, with each format's capacity reported on its own. Robot loaders that move wafers between baths and carriers count as wafer handling, and RoboTechnik prices them as separate items.
