PV-powered cars and the parking dilemma
Researchers in Portugal have addressed the so-called ‘parking dilemma’ of electric cars incorporating photovoltaic modules. They looked into the tradeoff between charging the car and raising its inside temperature. They calculated the critical time as a function of the car’s solar capacity.
Large area organic PV module achieves world record efficiency of 14.5%
The module has a size of 143 mm x 143 mm and an active area of 204.11 cm². The result was certified by the Fraunhofer Institute for Solar Energy Systems (Fraunhofer ISE).
Polysilicon prices further decouple, adverse factors thwart contract negotiations
In a new weekly update for pv magazine, OPIS, a Dow Jones company, offers bite-sized analysis on solar PV module supply and price trends.
