Just after analysts had said India’s solar quality control standards lacked clarity and investment in testing labs, the Ministry of New and Renewable Energy (MNRE) has brought forward the enforcement date in an attempt to ensure that quality control benefits the industry as soon as possible.
At the inaugural PV ModuleTech 2017 in Kuala Lumpur, it became clear that PERC module technology is fast becoming the industry standard and bifacial modules are no longer seen as a niche product, however, both technologies were scrutinised from the perspective of bankability and quality assurance studies throughout the event.
Aurora Solar Technologies' founder and COO Gordon Deans tells PV Tech how inline measurement and monitoring can protect yield, prevent process excursions and ultimately, ensure maximum profitability for PV manufacturers.
There are numerous tools and methods available on the market for the optical and electrical quality control of high-efficiency silicon solar cells during their industrial production, and even more are discussed in the literature. This paper presents a critical review of the possibilities and limitations of these tools along the value chain, from wafer to cell, in the case of passivated emitter and rear cells, as well as a discussion of some showcases. Economic and technological challenges and future trends are addressed.
