Based on technology, Royal DSM Group is active in the fields of health, nutrition and materials worldwide. Recently, it has launched a conductive backplane for high-power back-contact modules, which can improve the efficiency of solar modules. 3%.
This new technology benefits from the effective design of connecting adjacent cells to improve component efficiency and move high-power components to a new era of zero-loss conductivity, meaning zero power loss from battery to module. The advantage of back contact technology is that all solar cells have electrode contacts on the back side, so the front space of the module is maximized, capturing light and converting it into electricity.
Although back-contact solar modules made of conductive backplanes have been available for many years, they have not been widely used, which is largely due to conductive backplanes (combining metal foil with a "pattern" design with conventional backplanes, Thus achieving the function of component current sink output) has not yet been mass-produced at a lower cost. Today, however, DSM has solved this problem with its original conductive backplane production process, making conductive backplane production 100 times faster than before.
Back-contact solar modules can overcome the problem of traditional battery panel battery connection, reduce the energy loss caused by shadows, and shorten the battery pitch, thereby achieving higher power output. The design of the conductive backplane not only directs the current directly into the metal foil layer, but also provides various other functions with both aesthetic and design advantages.
The new conductive backplane has been planned for large-scale commercial production, and DSM's goal is simple and clear: to make high-power back-contact battery technology finally realize its unlimited potential.
Pascal de Sain, vice president of DSM's Advanced Solar Business Unit, said: "This new technology is a typical example of how DSM's innovative solar materials reduce the level of electricity costs, reduce dependence on fossil fuels, and make solar energy benefit the whole society. From a long-term perspective, our conductive backsheets have a wide range of application potentials in various fields. Now, we focus on commercial and residential roofs, as well as integrated building solutions. Maximum power output and aesthetic appearance are essential considerations . "
A solar module made from a conductive backsheet has been certified by TüV North Germany and is used in commercial modules produced by Exasun in the Netherlands. DSM expects to expand its customer base in Europe, Asia and North America by the end of this year.
