While shingled cells have been around for a while, Tongwei’s adoption of the technology is notable as it is a manufacturer with considerable scale. If shingling can overcome some hurdles, it could prove a welcome solution as unshaded sites for PV become elusive in mature solar markets.

An international research team has defined the operational parameters needed to design and manufacture crystalline silicon PV modules for tropical climates. The group proposed a back-junction, back-contact cell tech with a selective laser soldering technique it claims offers the best potential to yield such robust panels.

Researchers in Korea have proposed a new design for dividing and bonding which is said to provide higher efficiency from fewer fingers. The number of fingers optimized for division into five cells was 128 and for three, 171. Five offer power conversion efficiency of 17.346% and three 16.855%.

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.

A joint project conducted by the Carinthian Tech Research Center and the Austrian Institute of Technology, in conjunction with German equipment manufacturer teamtechnik has developed a lead-free PV system using glued ribbon technology.
