Inline measurement equipment specialist Aurora Solar Technologies (AST) has secured a new order from the world’s largest solar cell producer, expanding the use of its Decima 3T and Veritas servers for high-efficiency solar cell production.
PV Tech’s preliminary analysis of global solar PV manufacturing capacity expansion announcements in the first quarter of 2017, show a strong rebound compared to the significantly subdued environment experienced in the second half of 2016.
Taiwan-based cell and module producer Neo Solar Power (NSP) is feeling the impact of its shift away from multicrystalline cell production to become a differentiated producer of high-efficiency monocrystalline PERC (Passivated Emitter Rear Cell) and heterojunction (HJ) cells and modules as sales continue to decline through the first quarter of 2017.
Leading fully-integrated high-efficiency monocrystalline module manufacturer LONGi Green Energy Technology recently reported record total shipments and revenue for 2016, making it the fastest growing PV manufacturer in the industry.
This paper focuses on the technical progress of high-efficiency crystalline silicon solar cells and modules, specifically with regard to passivated emitter and rear cell (PERC) processes, module description and light induced degradation (LID) data. Through appropriate optimizations of the solar cell and module processes, the cell efficiency achieved in mass production is 21.3%, with module power exceeding 300W. To solve the LID problem, hydrogenation technology developed by UNSW is used, bringing the cell LID rate down to below 1%.
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.
PV and polysilicon manufacturing equipment specialist centrotherm photovoltaics reported 2016 revenue at the higher end of previously withdrawn guidance that was pulled on fears of PV manufacturers withdrawing capital expenditure plans when PV demand drastically weakened in China in the second-half of the year.
Dedicated monocrystalline integrated PV module manufacturer SolarWorld believes 2017 is a transitional year for the company after announcing a switch to monocrystalline production at the expense of multicrystalline and a full-migration to PERC (Passivated Emitter Rear Cell) technology as ASP declines in the second-half of 2016 forced a major manufacturing rethink.
REC Group has introduced an all-black variant of its ‘TwinPeak 2’ Series PV module for US and European residential markets. The REC TwinPeak 2 BLK2 Series has a nominal power rating of up to 285Wp, using its half-cut cell and PERC (Passivated Emitter Rear Cell) technology and uniformly black-colored multicrystalline cells.
‘Silicon Module Super League’ (SMSL) member Hanwha Q CELLS may have reported record PV module shipments and revenue for 2016 but the underlying strategy for 2017 is cash preservation after its gross profit and margins collapsed in the fourth quarter of 2016.
