The Photovoltaic (PV) industry has undergone rapid growth within the past decade, driven by Government incentives and feed-in tariffs to promote consumer acceptance. Generating power from renewable sources will continue to grow over the next 10-20 years as an increasing number of countries set minimum targets for the fraction of energy derived from non-carbon-emitting methods of generating electricity. Solar power is considered to be a leading environmentally friendly means of producing energy.
The manufacturing process for solar cell / module production should be as environmentally friendly as the basic concept of generating energy directly from sunlight itself via the modules produced. Non-contact laser-based systems, used within production-line tools, enable end-users to eliminate traditional approaches such as etching and screen-printing, which can result in toxic emissions or cause damage to wafers being processed.
The implementation of laser processes within the Solar industry is essential to the roadmaps being pursued by end-users over the next 5-10 years. Laser based manufacturing enables higher efficiency of the cells. Being a non-contact technology, lasers are essential for the use of thinner wafers reducing raw material costs. These benefits are enabling cell manufacturers to decrease $/Watt module costs as part of the drive towards “grid-parity”.

Coherent’s portfolio of diode-pumped Q-switched lasers, emitting from the infrared through to the ultraviolet (in particular the AVIA and PRISMA), is firmly established as a key enabler for many applications currently in production within the Solar industry, including both crystalline-Silicon (c-Si) and Thin-Film based cells. The lasers high quality output beams and unique pulse characteristics, coupled with very low cost-of-ownerships, allow yields and throughput to be optimized by the cell manufacturer.
Coherent is committed to playing a pivotal role within the supply chain for Solar cell manufacturing, and continues to research novel laser-based processes using both existing turn-key industrial-qualified products and next generation lasers.
