A precision DPSS-laser scribing platform engineered for P1, P2 and P3 scribing of thin-film photovoltaic materials — FTO, ITO, perovskite, SnO₂ and TiO₂. Designed and manufactured in India.

Wavelength selected to match the absorption of the layer being removed, so each scribe cuts what it should and leaves what it should not.
Narrow scribes keep the dead zone small, so more of the module area generates power.
Full research and pilot-line substrate sizes on a common stage.
Coordinated axes hold scribe straightness and dead-zone width across the full substrate.
Substrate registration so P2 and P3 land at the correct offset from P1.
Wavelength, power, frequency, speed and offset stored per material stack and recalled by name.
Interlocked enclosure with a viewport rated for the wavelengths in use.
In-house software for job setup, live monitoring, logging and export — written and supported by us.
One year warranty from acceptance, minimum five years spares, service and training by our own engineers.
A thin-film photovoltaic module is not built from separate cells wired together. It is deposited as continuous layers and then divided into series-connected cells by three laser scribes. P1 cuts the back contact, isolating one cell from the next. P2 cuts through the semiconductor layer to open a via that carries current between adjacent cells. P3 cuts the front contact to complete the isolation. The three scribes must sit within a narrow dead zone — every micron of misplacement is module area that generates no power, and a scribe that cuts too deep or too shallow shunts the cell.
Our Windows application handles live view, regions of interest, minimum, maximum and average values, trend plots and alarms, with export to Excel and MP4 and retention of raw data for re-analysis later. An SDK is available where the system is being embedded into your own application.
Because the software is ours, a change you need is a change we can make — you are not waiting on an overseas vendor's release cycle.
