10 years of R&D spending analysis of 12 key PV module manufacturers

PV Tech reached its own little milestone of having reported and analysed the R&D spending habits of the same 12 key PV module manufacturers for 10 years. The results have just been published in sister technical journal Photovoltaics International as part of the annual leaders and laggards of R&D spending for 2016.

The Value Proposition of Using High-Efficiency Mono-Si PERC Modules

In the past the value proposition of solar modules has been primarily about the lowest price ($/Watt) via the lowest manufacturing costs of conventional multi-Si modules. In the last few years, PV system cost has decreased significantly. In the meantime, PV module costs had dropped at a faster pace than Balance of System (BOS) costs, resulting in PV modules accounting for a smaller and smaller percentage of overall PV system costs.

SPI 2017: Solar modules pushing the bar on performance

Updated: With the solar industry transitioning to high-performance products backed with innovation, Solar Power International 2017 in Las Vegas is showcasing an ever increasing portfolio of solar modules exceeding 300 watts in the standard 60-cell format. However, 72-cell modules exceeding 360 watts are also entering the mainstream and 400 watts is just around the corner. Driving the high-performance wave is PERC (Passivated Emitter Rear Cell), bifacial and the migration to 5 busbars and beyond, whether with multicrystalline or monocrystalline wafers. The growing use of half-cut and multi-cut cells that reduce cell to module losses, boosting overall performance are also becoming mainstream as well as heterojunction (HJ) modules.

JinkoSolar working with Heraeus on next-gen solar cell R&D activities

Major metallization paste producer Heraeus Photovoltaics said it had signed a major strategic partnership agreement with ‘Silicon Module Super League’ (SMSL) leader JinkoSolar that will focus on what the company said would be the development of a new generation of “Super PV Cells” with higher efficiencies and lower costs.

LONGi fast-tracking capacity expansions as sales jump in Q2

‘Silicon Module Super League’ (SMSL) member LONGi Green Energy Technology and the leading fully-integrated high-efficiency monocrystalline module manufacturer, reported first half 2017 revenue slightly down from the prior year period as a result of average selling price (ASP) declines, partially offset by product shipment growth.

Innovative double-glass bifacial PERC modules by JA Solar yield cost-effectively for PV systems

The PERC (Passivated Emitter Rear Cell) cell and module technology have been widely adopted by the industry. JA Solar has been exploring innovative approaches of bifacial PERC cell and the methods of making it and has been granted two Chinese patents. Also, a series of experiments have been carried out to certify the higher efficiency of bifacial PERC modules than conventional PERC modules.
