Technology and R&D

Japanese scientists have designed a cooling system that reduces the solar panel operating temperature at the air inlet of the module. It consists of a dew-point evaporative cooler that supplies the near-saturation air to wet air channels that are attached to the back of a PV panel.

As solar manufacturing moves toward technological convergence, and rampant production capacity expansion continues, standing out from the crowd is just one of the strategies small- and medium-sized enterprises (SMEs) will have to use to survive, according to InfoLink’s Amy Fang.

As the energy storage trend unfolds, stories litter the media landscape about lithium-ion batteries catching fire, and even exploding. This is a valid concern, as the time for consumers to understand a basic truth about lithium-ion batteries is long past due.

The purchase follows Epsilon’s recent $1.1 billion investment in the establishment of a 100,000-ton cathode battery materials manufacturing facility in Karnataka, India.

Indian manufacturer Jakson has exhibited its 590 Wp TOPCon bifacial solar panels with a power conversion efficiency of 22.86% at Renewable Energy India Expo 2023.

Germany advanced its hydrogen ambitions this week with a fresh call for the International Green Hydrogen Promotion Program in Latin America, a collaborative deal with the UK government, and a tie-up between DHL and Sasol for sustainable aviation fuels based on green hydrogen (eSAF).

The two research institutes said the multijunction solar cell is based on silicon, gallium indium phosphide (GaInP) and gallium arsenide (GaAs). The device utilizes a specially designed metal/polymer nanocoating that reportedly optimizes the distribution of light scattering beyond the total internal reflection critical angle in the cell.

Exide Energy is setting up 6 GWh of lithium battery capacity initially, including 3 GWh for lithium nickel cobalt manganese oxide (NCM) and lithium iron phosphate (LFP) cells each. It plans to scale it to 12 GWh in the near future.

Honeywell purchased $27.5 million in ESS common stock and intends to purchase $300 million in ESS product, with $15 million prepaid. The collaboration enables Honeywell to integrate ESS technology into its global offering, and ESS gains license to Honeywell’s flow battery intellectual property.

The rise of cost-effective TOPCon cell technology last year led to a ‘surge’ in production demand for solar n-type cell technology, with leading industry analysts TrendForce prophesying PERC cell capacities ‘may’ be phased out in two to three years. The company’s experts, however, warn that oversupply for p-type cells and modules may increase the price gap between n-type and p-type products in the upcoming months.
