Singapore awards part of SGD$13 million research grant to improving cell efficiency

The call was focused on two topics: improving solar cell efficiency; and storage systems developed for renewable energy.

With part of the money, the industry’s direction in developing more cost effective solar energy systems will be looked at. To date, says the CEPO, substantial technological efforts have been focused on increasing solar cell, module and production efficiency, with the end-goal of cost reduction. Notable advancements over recent years include the use of thinner wafers, advanced manufacturing equipment enabling higher production rates, and thin film modules with improved efficiency.

The second topic – storage systems developed for renewable energy – seeks to "find solutions that will address the intermittency of renewable energy sources such as solar and wind, which represents one of the key challenges standing in the way of mass adoption". Sporadic energy production, continues CEPO, can make it difficult for utilities to balance supply and demand and could result in grid instability issues when the renewable energy contribution becomes substantial.

Managing director of the Singapore Economic Development Board (EDB), Dr Beh Swan Gin explained: “These research topics address the issues of cost-effective solar cells and renewable energy storage, both of which are critical to the development of clean energy markets globally.

“We believe that the five successful projects hold significant promise and could lead to commercially viable technologies that will enjoy mass adoption globally. This will help position Singapore as a leading player in clean energy research, innovation and commercialization.”
