Glow-in-the-dark dye could fuel liquid-based batteries

Charlotte Hsu for University of Buffalo:  BUFFALO, N.Y. — Could a glow-in-the-dark dye be the next advancement in energy storage technology?  Scientists at the University at Buffalo think so.

They have identified a fluorescent dye called BODIPY as an ideal material for stockpiling energy in rechargeable, liquid-based batteries that could one day power cars and homes.  BODIPY — short for boron-dipyrromethene — shines brightly in the dark under a black light.

But the traits that facilitate energy storage are less visible. According to new research, the dye has unusual chemical properties that enable it to excel at two key tasks: storing electrons and participating in electron transfer. Batteries must perform these functions to save and deliver energy, and BODIPY is very good at them.  In experiments, a BODIPY-based test battery operated efficiently and with longevity, running well after researchers drained and recharged it 100 times.  Cont'd...

PVinsights: Solar prices send bear signal with growth concerns lingering

Solar panel prices continue to drop this week as suppliers suffer from falling demand in EU and escalated price competition spooked by serious oversupply and unclear political environment. With the demand for PV installations in EU and the US beginning to wane on the advent of holiday season, solar panel prices in these regions continue to descent since only limited transactions are made during the holiday season. In addition, in the US market, competition among module makers remains strong so as to make the further pressures on solar panel prices. In India, the increasing demand could not sustain the prices as major players continue to offer slashed prices in the market in attempts to secure more orders. In China, the price is relatively stable due to solid demand in domestic market, but is dragged down in the dollar term with RMB deprecation. Consequently, exacerbating the problem is oversupply nature, which leaves competition remains fierce in major markets, as module players engage in unprecedented price reduction to secure orders.
