Manufacturing

Sunsolar recently advised of its plans to construct a 30MW solar PV manufacturing plant in Oldbury with a US$7.85 million (£5 million) grant from the Government fund backed by Sandwell Council and the Regional Growth Fund. Sunsolar will provide an additional US$7.85 million for the factory’s development, with plans to open the facility’s doors at the end of October.

Thin-film manufacturer NovaSolar has filed for Chapter 11 bankruptcy. That’s not unusual, a number of companies have gone bankrupt in the last months. NovaSolar, though, is the US arm of Chinese NovaStar, a company that was created with the remaining assets from bankrupt OptiSolar three years ago.

Under intense pressure to remain the low-cost leader, First Solar is taking a leaf from the semiconductor industry by teaming up with materials specialists Intermolecular to fast-track R&D research in materials and processes to shorten the time-to-market for higher efficiency CdTe-based, thin-film PV modules. Taking record cell and module efficiencies from the lab to the fab has proved to be a perennial problem for all types of PV technology.

The industry-renowned Intersolar Europe 2012 has presented Schott Solar and Schmid, Solon and Isra with the award for innovative photovoltaic technology.

Having previously announced a major reorganization of its entire operations, centrotherm photovoltaics, the second largest equipment supplier to the PV industry, has employed an outside consultancy to prepare discussions with its banks to secure further funding. The move was sparked by short-term liquidity issues after merchandise credit insurance companies, used for products and merchandise being delivered to the company, declined further coverage and guarantees.

bSolar, through its strategic partner and Japanese distributor TSBM, has won a contract to construct a 730kW ground-mounted solar project in Nasukarasuyama city, Tochigi, Japan. The project is expected to go online in December and will feature bSolar’s disruptive bifacial PV cells.

Thin-film manufacturer Masdar PV has reached 10% efficiency with its micromorph technology thin-film modules, the company has announced. Masdar’s research and development department collaborated with the Helmholtz Zentrum in Berlin, focusing on the optimization of materials used for the production of the modules.

Thin-film manufacturer DuPont Apollo has singed contracts to supply PV projects in Thailand with a total of 22.75MW of modules, the company has announced. The PV modules will equip two projects, one located in the Chaiyaphum province, owned by Smart Green Energy and a second one located in the Saraburi province, owned by Inifinite Green. DuPont Apollo is already involved in an 8.7MW ground mounted PV project in the Prachin Buri province, in collaboration with L Solar 1.

Molybdenum, commonly used as the back-contact material in CIGS solar cells, has been the subject of an in-depth study by sputtering target manufacturer Plansee, working in collaboration with TU Bergakademie Freiberg. Plansee’s results, presented at the ICMCTF Conference, identified the process errors and defect types present in molybdenum thin films that can have a detrimental effect on electrical conductivity.

Fraunhofer ISE recently confirmed that Kaneka and imec’s six-inch, semi-square, heterojunction silicon solar cell has a certified power conversion efficiency of 22.68%. The solar cell has an electroplated copper contact grid on top of a transparent oxide layer, which essentially replaces the traditional silver screen printing and is said to lead to higher efficiencies with lower manufacturing costs.
