Laser Processing in Industrial Solar Module Manufacturing Heather BOOTH Oerlikon Solar Ltd, Trubbach, Hauptstrasse 1a, 9477 Trubbach, Switzerland E-mail: heather.booth@oerlikon The use of lasers in the processing of solar cell structures has been known for many years both for c-Si and thin-film solar technologies. The maturity of the laser
Grooved solar cells are manufactured by scribing the surface of the substrate with a laser scribing tool, and optionally etching the surface to more accurately determine the surface profile, before performing the remainder of the processing steps involved in the production of the solar cell. Top contact shading is avoided by providing holes through the substrate which allow connection to
Recent studies show that plated contacts based on the latter can be more durable than screen-printed contacts. This work introduces a new concept of laser doping with grooving to form narrow grooves with heavily doped walls in a simultaneous step, with the self-aligned metal contact subsequently formed by plating.
In this work, laser illumination and temperature are used to control the position of the Fermi level [38], and therefore also the relative concentrations of hydrogen charge states, to passivate laser damage in LDG lifetime test structures and finished solar cells. 2. The laser doping and grooving process
This study presents an innovative approach to mitigate the cost of solar devices by employing luminescent solar concentrators (LSCs) that act as waveguides to direct sunlight toward photovoltaic (PV) cells. LSCs, while effective, face challenges such as escape cones and reabsorption losses during light concentration. To address these
Improvements in the performance of silicon solar cells based on a novel, laser grooved, buried contact approach are described. Independently confirmed energy conversion efficiencies as high as 19.8% are reported for cells of 12 cm 2 area, as are the resistivity dependence of efficiency, spectral response data, and the results of
This laser doping and grooving (LDG) approach capitalizes on the benefits of the BCSC, the high aspect ratio metallization, low shading loss, and strong metal adhesion strength, but with the simplicity of the LDSE solar cell processing sequence. The approach consists of a modified laser doping process in which narrow grooves with
Metallization plays both optical and electrical roles in the performance of a solar cell. Optically, the gridline width contributes to shading, which impacts the short circuit current.
This article introduces two different approaches for passivating the laser separated PERC solar cells. The first method is ''Laser scribing and simultaneous Al doping''.

Selective emitter solar cell through simultaneous laser doping and grooving of silicon followed by self-aligned metal plating . The higher laser-grooving power of cell 1 naturally introduced more defects to the Si. This resulted in lower Voc and FF in comparison to cells 2 and 3.

It is observed that the adhesion strength of laser-doped and grooved contacts is more than twice that of the laser doped (LDSE) cell and is slightly superior to the screen printed metal contact. This finding also supports the superior durability of BCSC compared to screen-printed solar cells reported elsewhere .
The narrow width and corresponding steep walls of the grooves make it possible to deposit the antireflection coating after the laser grooving process such that the groove walls remain uncoated to allow direct nucleation of subsequent metal plating.
This work introduces a new concept of laser doping with grooving to form narrow grooves with heavily doped walls in a simultaneous step, with the self-aligned metal contact subsequently formed by plating. This process capitalizes on the benefits of both BCSC and LDSE cells.
Not only does the laser doping and grooving process minimize laser-induced defects, it also defines the position for subsequent plated metal deposition. Since the top surface of the wafer is coated by SiN x, the exposed heavily doped groove walls define the plating nucleation location and hence the metal contact location.
