US solar cells to power India space satellite missions

EMCORE will manufacture and supply high efficiency multi-junction solar cells for Indian Space Research Organisation

The US solar cells are being used for telecommunication and scientific earth observation satellite missions in India

High efficiency US solar cells are being used to power space satellite missions in India. US solar cells supplier EMCORE Corporation has entered into a USD 22m supply contract with the Indian Space Research Organisation (ISRO) to manufacture, test, and deliver high-efficiency multi-junction solar cell assemblies for its commercial geostationary telecommunications and scientific earth observation satellite missions. The agreement continues EMCORE's relationship with the India space research organisation, which has supplied it with solar cell products for the past 15 years.

Over the term of the multi-year contract, EMCORE said it expects to deliver Coverglass Interconnected Cells incorporating its highest-efficiency ZTJ and ATJ solar cells for multiple satellite missions.

The PV industry has seen significant efficiency boosts in US solar cells this year. This includes US firm Alta Devices, which achieved 30.8 per cent efficiency with its next generation solar cells in March.

With a conversion efficiency nearing 30 per cent, EMCORE said the ZTJ solar cell is one of the highest performance multi-junction solar cells available on the market today.

Brad Clevenger, general manager of EMCORE's Photovoltaics Division, said: "This contract is a very significant award for EMCORE. It further reinforces our successful heritage in the Asia-Pacific satellite market, and expands our market share for both commercial and scientific missions. EMCORE has partnered with ISRO on many successful satellite missions, and we greatly value our long-standing business relationship. We look forward to supporting ISRO on its next phase of telecommunications and earth observation satellites."

Over the past four decades ISRO has launched more than 65 satellites for various commercial and scientific applications. EMCORE is a leading provider of compound semiconductor-based components and subsystems for the fiber optic and solar power markets. The US solar cells firm has been a key supplier of solar cells to ISRO for the past 15 years, including supplying solar energy equipment to power several INSAT telecommunications missions.
