Optimizing electrically conductive adhesives for solar cell interconnections
German research institute ISC Konstanz has developed a new method to measure the contact resistance of solar cell interconnections made with electrically conductive adhesives (ECA). The proposed approach reportedly enables the precise characterization of both contact resistivity and bulk resistivity.
Organic solar cell with bilayer hole transport layer achieves 17% efficiency
A research team from two Chinese universities claims to have fabricated an organic solar cell with the highest power per weight ratio to date. The device has a thickness of less than 1.5 micrometers.
Tesla battery deployment soars in Q2

Chemitek offers metal oxides removal agent for PV panels
The Portugal-based company has developed a metal oxides removal agent product for PV installations located near foundries, steelworks and metal ore mines.
US DOE allocates $100 million for non-lithium, long-duration energy storage pilots
The US Department of Energy’s (DOE) Office of Clean Energy Demonstrations (OCED) has issued a Notice of Intent (NOI) to fund pilot-scale energy storage demonstration projects, focusing on non-lithium technologies, 10+ hour discharge systems, and stationary storage applications.
The importance of measuring albedo at solar sites
As bifacial modules proliferate, estimations of albedo are becoming more important and with developers not prepared to install weather stations to assess solar resource, a popular option has become third-party, on-site measurements over periods as short as a day. Is this an acceptable compromise between costly on-site measuring and less accurate satellite data? Everoze’s Stefan Mau discusses the potential benefits and limitations of this approach.
Ukraine receives solar panels to power hospitals
Over 5,800 solar panels manufactured by Italy’s Enel have been delivered to Ukraine to help power healthcare facilties.
European Energy secures solar PPA from Danish State Railways
Danish State Railways has agreed to purchase 80 GWh annually from a PV plant planned to occupy a surface of 253 hectares.
