May 30, 2014,15:40 +0900(JST) Our High-Performance Concentrator Photovoltaic System
Some time ago, when I attended a workshop by researchers at the Osaka Works, I had an opportunity to observe concentrator photovoltaic (CPV) system production.
The Sumitomo Electric Group has developed a high-performance CPV system, using a compound semiconductor with high photoelectric conversion efficiency, combined with a collective lens to intensify the light energy and a tracking system to maintain an optimal angle to the sun. Since launching commercial sales at the end of March, we have been receiving many inquiries.
The successful development of this CPV system is owing greatly to the effective use of existing technologies dispersed throughout our group. We have many business units within the Group, but regrettably we sometimes focus too much on our own area of specialization and overlook the benefits of interdivisional cooperation. I personally feel that active interdivisional communication generates synergy and produces innovation.
Our engineers still recall that, at their early stage of solar panel development, as they did not have measurement equipment, whenever the sunlight appeared, they would rush outside to measure the conversion efficiency. After repeated experimentation inside and outside the company, with steady product improvement, the development team proudly launched the first commercial product.
Although our CPV system market is still in its infancy and there are many challenges to overcome, we will make concerted efforts to make it a stable business. We ask for your continued support and encouragement.
