The Singapore team, led by Assistant Professor Wang Qijie, from NTU’s School of Electrical & Electronic Engineering, has developed a graphene sensor that is 1000 times more sensitive to light than current imaging sensors used in today's digital cameras. Remarkably, it also uses 10 times less energy because of its lower voltage requirements. The researchers believe it can be mass produced.

Sorry, Paul.

Follow the links that the your links link to. It all comes back to this "new" graphene sensor being 10-20 times more sensitive than existing graphene sensors, which had yet to exceed an ISO of 1 at the time Qijie made his press release.

The 1000 times more sensitive than existing CMOS claim is a creation of the popular press. It was a three year old article in Nature that first "evolved" Qijie Wang's claim of 20 times more sensitivity than existing graphene sensors into 1000 times more sensitive than existing graphene sensors, then the popular press took off with it and somehow made that 1000 times more sensitive than modern CMOS sensors.

Basically, you can add graphene to the list of things that aren't going to do anything really useful, along with nanotechnoology, AI, quantum computing, neural network, and genetic algorithms.
