Efficiency of the thin-film solar cells with a large active area can be increased if small segments are connected in series in order to reduce recombination in thin films and related current loss. Thin film solar cells consist of basically three functional layers, i.e., Mo, CIS and ZnO. The paper presents the results of preliminary study on the laser machining characteristics of thin films used for solar cell panels by using picosecond laser scribing. The material used in the preliminary study is a...$28.00

Presented at ICALEO 2010
Laser technologies in solar cells production, like P1, P2 and P3 structuring, Vias Drilling, Marking, Edge Isolation, can be improved by applying the beam shaping optics that transforms the intensity distribution of laser beam to flattop, donut-like or other profiles. The flattop profile leads not only to higher quality and stability of such techniques like scribing, drilling, but also increases efficiency of using the laser energy and, hence,...$28.00

We demonstrate a compact diode-pumped Yb:YAG Innoslab femtosecond oscillator-amplifier system with nearly transform and diffraction limited 636 fs pulses at 620 W average output power and 20 MHz repetition rate. By cascading two amplifiers an output power of 1.1 kW and peak power of 80 MW is achieved. To our knowledge this is the highest average power f...$28.00

Choice of Laser Sources for Micromachining Applications
Authors:
Mohammed Naeem, JK Lasers; Rugby Great Britain
Presented at ICALEO 2010
The increasing complexity of microelectronics/ engineering devices and the requirement for higher yields and automated production systems place stringent demands on the assembly techniques and performance requirements of materials, machining and joining techniques. This has led to increasing interest in the use of low power lasers for cutting, drilling, welding, soldering and marking of small assemblies. Of particular interest to micro-component industries is the ability of such lasers to apply controlled amounts of energy in precise areas, utilizing extremely...$28.00
