Fast growing Midsummer named as one of the most interesting cleantech companies in Stockholm

[Stockholm, Sweden, 16th October 2014.] Midsummer, a leading supplier of production lines for cost effective manufacturing of flexible thin film solar cells, CIGS, has been named as ‘one of the most interesting cleantech companies in Stockholm’ for its ‘unique product with global potential’.

Midsummer is featured as one of the 25 most interesting cleantech companies in one of the world’s leading tech regions, Stockholm. The Stockholm Cleantech Hotlist is a tool that presents the region’s hottest prospects to investors. To qualify for the list, the companies must offer a product or service based on unique research that will lead to a commercial solution with global potential. The Stockholm Cleantech Hotlist is compiled by Stockholm Business Region Development and Cleantech Scandinavia.

Midsummer is a leading global provider of turnkey production lines for cost-effective manufacture of flexible thin film solar cells of the type CIGS (copper, indium and gallium). Midsummer has developed a rapid process for the production of these solar cells using sputtering of all layers of the solar cell. This allows for scalable and cost efficient manufacturing of thin film solar cells.

“The Stockholm Cleantech Hotlist is yet another proof that our offering is of great interest to the global market. We firmly believe that thin film CIGS solar cells are the solar cells of the future", said Sven Lindström, CEO, Midsummer.

“Flexible thin film solar cells are increasingly efficient and have many advantages over traditional silicon-based solar cells. They are durable, can withstand vibrations, can be curved and bent, and can be manufactured cost-efficiently in small volumes”, Sven Lindström continued.

CIGS flexible solar modules are growing in popularity thanks to their low weight, flexibility and durability. Applications are e.g. floating modules, vehicles, landfills, portable power generation and membrane roofs on factories, offices and other structures that are not strong enough for traditional glass modules.

Midsummer has been named as one of Sweden's hottest technology companies and also been repeatedly featured on the list of the nation's fastest growing technology companies. Midsummer was the fastest growing clean tech company in the EMEA region in 2007-2011 (Deloitte, Fast 500).

About Midsummer
Midsummer is a leading supplier of equipment for cost effective manufacturing of CIGS thin film flexible solar cells. Midsummer’s turnkey manufacturing lines have a small footprint, are perfectly scalable and allow for small-scale production of solar cells and modules.

Midsummer’s customers are thin film solar cell manufacturers all over the world. CIGS flexible solar modules are growing in popularity thanks to their low weight, flexibility and durability. Applications are e.g. floating modules, vehicles, landfills, portable power generation and membrane roofs on factories, offices and other structures that are not strong enough for traditional glass modules.

Founded in 2004 by people with a background from the optical disc manufacturing equipment and the photo mask industry, Midsummer has its head office in Stockholm, Sweden. Midsummer was the fastest growing greentech company in EMEA (Europe, Middle East and Africa) in 2007-2011 (according to Deloitte).

About CIGS thin film solar cells
CIGS stands for copper-indium-gallium-selenium, a metal alloy that converts the energy of light directly into electricity by the photovoltaic effect (PV). The CIGS absorber is deposited on a stainless steel substrate, along with electrodes on the front to collect current. The cells are then connected in series and covered by a protective layer of plastic to form a flexible solar module.

Since a stainless steel substrate is used, the modules can be made without glass. The CIGS solar modules are therefore much lighter, flexible and can be made frameless, to suit applications where traditional silicon solar cells cannot be used, e.g. on structures that are uneven, moving or weak.

CIGS solar cells are manufactured by sputtering the material onto 156x156 mm stainless steel substrates. The solar cells from Midsummer are free of cadmium, a toxic material usually used in CIGS and other thin film solar cells. Flexible CIGS solar modules are gaining market share thanks to its high efficiency, low weight, flexibility and durability.
