Will flexible solar cell succeed in the PV market?
Yole Développement interviewed Rich Kapusta, Vice President of Sales and Marketing, Alta Devices, GaAs solar cell developer. In 2013, Alta Devices achieved 30.8% efficiency record with a dual junction technology based on GaAs/InGaP materials.
According to Yole Développement technology and applications analysis (detailed in the new Emerging and Innovative Approaches in Photovoltaics report), Alta Devices’ approach is unique of its genre. Actually, the use of III-V semiconductors in dual-junction configuration and removal of rigid substrate results in a flexible & lightweight solar cell with very high efficiency. Such products, once the manufacturing costs lowered, might open a new field of PV applications, such as powerful PV chargers for portable devices or for automotive applications.
Yole Développement: Can you present us the activities of Alta Devices?
YD: What is the status of development of Alta Devices products for PV business? What are the main advantages of your technology?
YD: How do you position your products amongst other flexible PV products (made by CIGS companies, for example?) From Yole Développement analysis, your company has better performance and reliability, but also much higher costs. Can you provide for insights on this point?
YD: What are the targeted applications for such products? What is the potential for manufacturing cost decrease?
YD: In December 2013, China's Hanergy has acquired Alta Devices. What has changed since that time in the company (business, technology improvement)?
YD: As Hanergy purchased several other thin film companies (Solibro, MiaSolé, Global Solar Energy – all CIGS technology – not the same as GaAs technology of Alta Devices) during 2012-2013, what is the positioning and matching of Alta Devices with these companies?
YD: How do you see the future for the flexible PV cell, for military applications but also for other business?
YD: What are the next steps of the development of Alta Devices?
