The UK Government has announced £36 million worth of funding for the development of green energy in the construction sector in Wales.
The funding will go to the SPECIFIC research institute, part of Swansea University, which develops new building materials and coatings that can generate electricity from light and heat.
The energy generated can then be used to power homes or be sold back to the national grid.
The funding is part of the UK Government's attempt to make homes more energy efficient over the next 10 years.
Chancellor of the Exchequer, Philip Hammond praised Swansea University's innovation in clean energy.
