Solar inverters vs. cyberattacks
A U.S. research group is developing inverters and cybersecurity standards to protect solar installations from cyberattacks. The researchers said that inverters can shut down if they are hacked, or contribute to grid instability and result in the overcharging of batteries, while potentially creating problems that we still don’t know how to address.

Assessing the sustainability of existing photovoltaic technologies
Solar PV technologies are expected to play a massive role in the world’s battle against climate change; headed for a global deployment of 7.5 TW by the year 2050. However, a number of PV chemistries exist in the market and PV modules get better in performance and durability by the year. This analysis looks at various PV technologies and develops a technological and ecological rationale for the best PV technology mix to combat global warming
Can a transparent solar window harvest enough power to be practical?
Can an organic solar cell material finally be commercialized? Last year, Ubiquitous Energy claimed a world record for efficiency of a “transparent solar cell” with a “certified” 9.8% efficiency.
Hot electrons? Surface plasmons? Thin-film solar innovation marches on
Thin-film solar startup PI Energy didn’t disclose the photovoltaic materials system it’s been commercializing, other than to say that it wasn’t CIGS, CdTe, or perovskites.
