    The environmental impact of electric vehicles depends on the kind of energy used to charge them. They are typically charged at peak times, when extra fossil fuels are needed to meet energy demands. A study shows that e-mails targeting electric vehicle charging for new owners can be effective for promoting greener charging behaviours.

Traffic control in silicon

Back-contacted silicon solar cells with interdigitated passivated contacts have high efficiencies but are complex to manufacture. Tomasi et al. now report a simple process to self-align the two types of electronic contacts based on the surface-dependent crystalline growth of silicon and fabricate solar cells with a certified efficiency above 22%.
