JinkoSolar today announced that it has set a new efficiency record for a monocrystalline PERC PV cell at 24.38%, and produced a module that achieved 469.3 W power in testing conducted by TÜV Rheinland. The Chinese module manufacturer also equalled a record claimed just last week by Trina Solar, of 24.58% conversion efficiency for an n-type monocrystalline cell.
Chinese module manufacturing giant JinkoSolar today published its financial results for the full year 2018. While the company achieved an impressive 16% growth in shipments over the previous year, its total revenue took a 5.4% hit compared to 2017, thanks to falling module prices throughout the year.
Having quickly proven their performance boosting potential and durability, anti-reflective coatings are now found on the majority of modules rolling off the world’s production lines. Today, coating suppliers are looking to tackle losses from soiling as well as reflection, and working to keep up with cost reductions and extended lifetime expectations at module level. Older modules, installed without a coating, could also be set to benefit from their latest innovations.
Belgian research institute imec has developed a new simulation framework it says can calculate the expected output of a bifacial PV system. The model could help improve developer understanding of the best system configurations for bifacial, and foster confidence among investors by providing a precise prediction of energy yields.
From a little known niche just a few years ago, floating solar has quickly grown to more than 1 GW of installed capacity worldwide, and a source of great hope for the industry’s future, particularly in countries where space for solar is at a premium. pv magazine spoke with experts from leading floating PV test centers in Singapore and the Netherlands to outline the challenges still faced by floating PV as the technology moves towards major growth.
A team of researchers from Germany’s Martin Luther University Halle Wittenberg has developed a new approach to perovskite cell production, which they say could result in better stability and longer lifetimes. The team also made detailed observation of the perovskite’s formation and decay, which could help to inform further research into high performance solar cells.
Research conducted over several years by scientists at the Massachusetts Institute of Technology (MIT) demonstrates that air pollution in cities can put a dampener on the performance of PV panels which, if not taken into account, can threaten a project’s viability.
According to PV Info Link, the price for monocrystalline cells in China fell below that of the usually cheaper multicrystalline products. However analysts expect it to be a blip, with multi prices expected to fall and mono to be supported by the Top Runner Program, now China’s main source of demand for the rest of 2018.
Researchers at UNSW have surpassed 10% efficiency for a cell based on copper zinc tin sulfide – sulfide kesterite. It is the fourth time in two years the group has set a new record for the efficiency of cells based on such materials.
