Phosphorus-arsenic nanoribbons may improve solar cell performance
UK researchers have developed ultra-thin nanoribbons, just 1 atom thick, by combining phosphorus and arsenic alloys. The nanoribbons offer excellent conductivity, even at temperatures exceeding -143.15 C, and have the potential to enhance charge flow in solar cells.
Panasonic introduces half-cut HJT residential solar modules
Panasonic unveiled its new residential solar modules – including half-cut heterojunction (HJT) models, along with a home battery system and energy management device – at the recent RE+ trade show in Las Vegas.
French developer builds agrivoltaics facility with irrigation system
TSE has installed a 2.9 MW agrivoltaics plant in northern France with sensors to trigger an irrigation system. The irrigation setup can reportedly achieve significant water savings. The company is selling the electricity under a 20-year power purchase agreement (PPA).
Honeywell invests in US iron flow battery specialist ESS
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.
Assessing non-linear tradeoffs in photovoltaic mini-grids
Researchers in Sweden investigated the complex non-linear tradeoffs between capacity expansion costs and reliability levels of off-grid PV mini-grids and found that capacity expansion based solely on cost-minimization may result in several reliability issues.
Rinnai launches hot water heat pump for residential applications
The new heat pump can purportedly provide hot water at a temperature of up to 70 C. It is specifically designed for climatic conditions with temperatures ranging from -10 C to 42 C, as well as coastal locations.
Riello Solartech unveils hybrid inverters for rooftop PV
Riello Solartech has developed new hybrid inverters for rooftop PV, designed for commercial and industrial applications The Italian manufacturer says they have a European efficiency rating of roughly 98%.
Fraunhofer ISE, AMOLF claim record efficiency of 36.1% for silicon-based multijunction solar cell
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.
