3-D nanocone solar cell boosts PV conversion efficiency by nearly 80%

Green Car Congress

With the creation of a 3-D nanocone-based solar cell platform, a team led by Oak Ridge National Laboratory’s Jun Xu has boosted the light-to-power conversion efficiency of photovoltaics by nearly 80 percent. The technology substantially overcomes the problem of poor transport of charges generated by solar photons.

Toyota Research Institute and Northwestern partner to accelerate new materials discovery with nanomaterial data factory; fuel cell catalysts first

Green Car Congress

While the first application of the data factory will be used to discover new catalysts to make fuel cell vehicles more efficient, TRI and Northwestern believe this method of materials discovery will have wide-ranging applications in the future such as clean hydrogen production, CO 2 removal from air and high-efficiency solar cells.

Northwestern team develops new approach to catalyst design using SPBCL and DFT; new HER catalyst 7x more active than Pt

Green Car Congress

In this work, we introduce an effective approach that combines computational prediction, experimental verification using a well-defined nanomodel, and finally production of high-performance catalysts in bulk as a powerful tool for discovering and designing catalysts for energy conversion and storage. —Professor Chad A.

Africa’s Electricity-Access Problem Is Worse Than You Think

Cars That Think

Similarly, having a distribution line (often illegally rigged) running to a dwelling tells us nothing about the usage of power or the reliability of its supply. This means that in 2019 about 770 million people had no electricity, three-quarters of them in Africa. What does 50 kWh/year deliver?

The Top 10 Semiconductor Stories of 2023

Cars That Think

Silicon carbide and gallium nitride power semiconductors are both more efficient than their silicon counterparts. Intel Is All-In on Back-Side Power Delivery Intel Chipmakers plan a big change in the architecture of interconnects in high-end processors. Basically, less power is lost if the interconnects carrying it are short and wide.
