A high profile solar power company, which employs 40 staff in Cardiff, has gone into administration.
G24 Innovations designs flexible solar panels capable of powering mobile phones.
It has a 120 metre high wind turbine outside its factory on the eastern edge of the city.
Administrators Wilkins Kennedy said they hoped to save the business as a going concern and preserve jobs.
The company came to Wales in 2006 saying it planned to create 300 high tech jobs with a £60m investment.
It is unclear whether the job creation ever reached those figures.
A Wilkins Kennedy spokesman said joint administrators were appointed on 3 December.
"The company's affairs, business and property are now being managed by the joint administrators.
"The purpose of the administration is to save the business as a going concern and preserve the jobs of the employees and by doing so achieve a better result for the company's creditors as a whole than would be likely if the company were wound up," he said.
Creditors will receive a report "as soon as it is reasonably practicable".
