Laser beam sha** and homogenization techniques are substantial to optimize a large
number of laser-material processing applications and laser-material interaction studies …

Recently, a so-called “directly induced” laser ablation effect has been reported, where an
ultra-short laser pulse (660 fs and 1053 nm) irradiates a thin Mo film through a glass …

In this paper, we investigate the laser processing of the CIGS thin-film solar cells in the case
of the high-speed regime. The modern ultra-short pulsed laser was used exhibiting the pulse …

Transparent oxide back contact of Cu (In, Ga) Se2 (CIGS) solar cells is crucial for
semitransparent or bifacial CIGS photovoltaics. Parasitic GaOx resistive layer formed at the …

Ultrashort laser pulses with durations in the femtosecond range up to a few picoseconds
provide a unique method for the structuring of practically all materials with high precision …

The thin-film CIGS technologies for photovoltaics are attractive due to their potential low cost
and optimal performance. Efficiency of cells with a large area might be maintained if small …

Transparent conductive oxide (TCO) thin films were removed from glass substrates using
femtosecond laser pulses. Irradiating through the glass, the threshold for complete TCO …

Abstract Monolithically integrated Cu (In, Ga) Se2 mini‐modules were fabricated in order to
reduce the width of patterning related dead area. The Cu (In, Ga) Se2 layers were prepared …

Continuous growth of the thin-film solar technology market stimulates the development of
versatile technologies for large-scale patterning of thin-film materials on rigid and flexible …

In this paper, we present the selective structuring of all three patterns (P1, P2 and P3) of a
monolithic interconnection of CIS (Cu (In, Ga)(S, Se) 2) thin film solar cells by picosecond …
