Who maintains the chargers?

While much of the focus on electric vehicle (EV) charging infrastructure focuses on volume, what about quality? And who is going to maintain a multi-million strong fleet of EV chargers?

PV-driven water splitting system with solar-to-hydrogen efficiency of 9.8%

Scientists in Korea have built a green hydrogen system prototype that embeds a PV generation unit based on photoanodes made of perosvksite solar cells. The device purportedly achieved a solar-to-hydrogen efficiency of 9.8% for a device with a size of 0.25 cm2, and 8.5% for a system measuring 123.2 cm2.
