Flexible solar cells reach high efficiency and pass a tough endurance test
Chinese researchers have made flexible solar cells that also work well as larger panels. A small cell converts a certified 26.9 per cent of sunlight into electricity. After more than 1,000 hours of heat and humidity, a test panel kept 92.5 per cent of its efficiency.

Artificial leaf from Singapore uses sunlight to make hydrogen from seawater and clears up a poison at the same time
Researchers in Singapore built an 'artificial leaf' that, without power from outside, gets hydrogen from polluted seawater and at the same time breaks down the toxic substance hydrazine. It is a first working prototype; the next step is a larger and longer-lasting device.

Chemical lock helps organic solar cells keep working well for longer
Chinese researchers have chemically fixed a very thin, fragile layer inside organic solar cells. Small cells reached 20.4 per cent efficiency, larger modules 18.8 per cent, and after 2,000 hours in the light the tested cells still delivered more than 85 per cent of their starting efficiency.

Lid insert with a sunlight catalyst takes the stink out of the bin
Chinese researchers have built a transparent insert for the lid of a wheelie bin. A lens focuses sunlight onto a cheap catalyst, which breaks down the sour smell of rotting waste. In an outdoor test it did so for more than 40 days in a row.
