Solving the UV problem of n-type solar

Laboratory testing has revealed that some negatively-doped, “n-type” tunnel oxide passivated contact (TOPCon) and heterojunction (HJT) solar modules are susceptible to ultraviolet (UV) light-related damage and degradation. That could mean trouble down the line, if modules in the field begin to show UV-related performance loss. Manufacturers are implementing solutions at cell and module level.

Powering restaurants with rooftop PV, reversible fuel cells

Researchers have simulated the operation of bifacial PV and proton exchange membrane reversible fuel cells across restaurants in five different US states. Taking into account varying rates of bifacial PV’s rearside gains, they found that LCOE was as low as $0.029 per kWh.

The Hydrogen Stream: Ballard restructures, Forvia supplies hydrogen tanks

Ballard Power Systems says it has started restructuring its global operations to cut costs due to slower hydrogen infrastructure development and delayed fuel cell adoption.

California hits new milestone with EV chargers

California installed 24,202 electric-vehicle chargers in the first half of 2024, bringing the total to more than 150,000.

New bidding strategy for PV asset owners operating in spot market

Conceived by an international research team, the new bidding strategy applies to the day-after and the intraday markets. It uses a technique that transforms results from probabilistic models into actual scenarios. Their method showed its ability to yield increased revenues and reduced imbalance.

Battery fire shuts down California highway

A utility-scale battery delivery overturned on a highway after the truck carrying the batteries collided with a car, overcorrected, tipped to the side and dumped its cargo, leading to a fire that lasted more than 24 hours.
