Company scope
What the company makes
Hymson Laser Technology Group makes laser and automation equipment used in solar cell, battery, electronics and sheet-metal production. The company dates its founding to 2008 and its STAR Market listing to 2020. Its 2025 annual report carries the Chinese company name and the stock code 688559.
PV buyers should go straight to the HL-KZPCNS-HO, Hymson's automatic TOPCon laser doping machine. The battery welders and metal-cutting lasers elsewhere in the group catalogue belong to other businesses, so judge the solar offer on this machine and on trial results from your own wafers.

Automatic TOPCon laser doping machine →
The HL-KZPCNS-HO is Hymson's automatic laser doping machine for TOPCon cells. It uses the borosilicate glass layer as the dopant source, places the laser with vision positioning and moves wafers on automated transport. Hymson quotes throughput separately for 182 mm and 210… [1]

HL-KZPCNS-HO throughput, size and process step
| Item | Hymson figure | Applies when |
|---|---|---|
| 182 format capacity | ≥8400 pcs/h | Fewer than 132 grid lines |
| 210 format capacity | ≥7300 pcs/h | Fewer than 152 grid lines |
| Machine dimensions | 5500 × 2300 × 2500 mm | Signal light, dust unit and cooling not included |
| Production space | 9600 × 3260 × 2800 mm | Floor area to plan for, larger than the machine itself |

One selective-emitter step inside the cell line
Hymson describes laser doping through the borosilicate glass layer to create a heavily doped zone for a TOPCon selective emitter. The English description is hard to follow in detail and gives no full diffusion or oxidation recipe. Ask Hymson to state the surface it expects to receive, the pattern its laser writes and where its responsibility ends. That line matters most when another supplier builds your furnace and wet benches. [1]
Alignment and breakage figures
Hymson builds the machine around its own laser design, special optics, vision positioning and flexible wafer transport. The sheet lists ±15 μm pattern and alignment accuracy and a breakage rate of 0.02% or less. Run the acceptance trial on your real wafer thickness and pattern, count handling losses, and measure cell electrical results after the downstream steps. Any efficiency gain shows up only in those downstream cell measurements, so write them into the trial plan. [1]
Company organisation
Which Hymson base serves a PV order
Shenzhen headquarters and regional bases
Hymson is headquartered in Shenzhen and runs production bases in Shenzhen, Jiangmen, Changzhou and Chengdu. The company links its Jiangmen subsidiary to sheet-metal equipment and battery manufacturing in southern China. The Jiangsu operation serves new-energy industries, photovoltaics among them. Chengdu combines R&D and operations for several new-energy uses. Ask which of these bases will build your machine. [2]
Overseas subsidiaries and local service
Hymson lists overseas subsidiaries in several regions. For a TOPCon machine installed abroad, what counts is the named engineer, the spare-parts stock and the response time at your site. Ask for the contracting entity, build location, installation team and service terms for the quoted configuration. The annual report confirms the company's identity, while machine performance is settled in your own acceptance trial. [2][3]
Project fit
Match the offering to your project
Hymson suits a buyer who needs one defined TOPCon selective-emitter laser step. Compare its offer against your incoming surface, grid pattern and full handling cycle. A quote for this step covers this machine, and the rest of the cell line needs its own suppliers and warranties.
Confirm before ordering
- The current revision of the HL-KZPCNS-HO parameter table, since the live product page now shows only the process text.
- Breakage, electrical results and sustained throughput measured on your own wafers in a sample trial.
- Which Hymson entity builds the machine and who commissions it at an overseas site.
Hymson's photovoltaic offer here is the HL-KZPCNS-HO; battery-machine figures and general efficiency promises from the group catalogue are left out.

Is the machine footprint the floor space I need?
No. Hymson gives 9600 × 3260 × 2800 mm as production space, larger than the 5500 × 2300 × 2500 mm machine, and the machine size leaves out the signal light, dust unit and cooling. [1]
Will Hymson's overseas subsidiaries support a TOPCon machine in my country?
Hymson lists subsidiaries in several regions. Put the support team, spare parts and response time for your quoted machine into the contract. [2]
What should a sample trial on the HL-KZPCNS-HO measure?
Run your own cell architecture, wafer thickness and doping pattern. Agree up front how edge damage, electrical change, handling losses and accepted pieces are counted. The result that matters is how the processed wafers perform in your next process steps.
