heterojunction

Sharp has released three new high-efficiency mono-PERC solar panels. Ranging from 300 W to 370 W, the five-busbar modules are designed for use in a range of applications, from residential PV projects to large commercial installations.

Meyer Burger Technology’s largest single shareholder has followed up on its recent call for the Swiss technology group to embark on a new strategic path by launching a new website.

Meyer Burger has struck a strategic partnership with Oxford PV to expedite the mass production of perovskite on silicon heterojunction (HJT) tandem cells.

Chinese PV manufacturer Hanergy Thin Film Power Group today announced it has achieved 24.23% cell efficiency using its silicon heterojunction technology. The efficiency has been confirmed by Japan’s Electrical Safety & Environment Technology Laboratories.

Among n-type manufacturers, SunPower, Panasonic, and LG had the leading roles in interdigitated back contact (IBC), heterojunction (HJT), and tunnel oxidized passivated contact (TOPCon), respectively. But Chinese cells with low cost and high efficiency trends have been on the rise. In the future expansion of n-type production lines, the power of Chinese cell manufacturers and equipment makers can’t be underestimated.

Scientists at France’s Alternative Energies and Atomic Energy Commission, working with Swiss equipment supplier Meyer Burger, have hit 23.9% efficiency in large-scale production of heterojunction cells. The team also combined HJT cells with other technologies to produce a module with a 348 W power rating.

Swiss equipment supplier Meyer Burger has received a CHF 74 million (US$74.4 million) order for a 600 MW production line combining heterojunction and smart wire technologies. The order was placed by an unnamed manufacturer, with the line expected to begin cell and module production in the second half of 2019.

Meyer Burger’s largest single shareholder has requested the company change strategy. Sentis Capital has urged the Swiss technology company’s board to raise sufficient capital for it to set up its own GW-sized production facility for its heterojunction and tandem cell PV technology. Meyer Burger has responded that it is view of only one shareholder.

Researchers from Berlin’s Helmholtz Zentrum Research Institute have developed a silicon heterojunction cell, with an additional crystalline layer that utilizes an effect known as singlet fission to boost efficiency. The team has created a device demonstrating that the principle works, and says that with further experimentation, the concept could achieve cell efficiencies as high as 40%.

For the production of its heterojunction modules, the Russian manufacturer will cooperate with the German PV engineering provider for the supply of stringers and adhesive technology. To this end, Hevel has ordered new stringer systems and layup from Teamtechnik.
