The energy transformation has brought us global challenges. In this regard, renewable energy sources such as photovoltaic are crucial. The key to improving the efficiency of photovoltaic power generation is to improve the manufacturing process of solar cells. Laser material processing is used to weld individual batteries into modules, dope selective emitters, and remove very thin antireflective and passivation layers.

In addition to cost-effective and rapid production, this process also provides other advantages for the industry, such as high precision and achievable linewidth of several micrometers. The F-Theta lens S4LFT1330-075 has been developed specifically for such applications.

Especially, lasers within the ultraviolet range are used to remove anti reflective and passivation layers. These layers improve optical and electrical performance, thereby increasing the efficiency of solar cells. In the ultraviolet range, a particularly small focal size allows for a corresponding narrow linewidth.

Sill Optics GmbH has become a leading supplier of F-Theta lenses in the photovoltaic field. Although S4LFT1330-075 is suitable for M12/G12 wafers, it can also process smaller wafers up to M2.

The S4LFT1330-075 lens is suitable for the wavelength range of 343 nm to 355 nm, with a spot size of<18 μ m. On a field of view of 210 mm x 210 mm. This product series includes other lenses with similar specifications, which are also designed for other wavelengths in the green and infrared ranges.
