    Electrek Green Energy Brief: A daily technical, financial and political review/analysis of important green energy news

    Trina Solar achieves 24.13% conversion efficiency for IBC solar cell – Cool to see the R&D happening not only in the labs of universities, but also the largest companies on the planet. A few notes though – this was a single cell. Trina Solar noted that the record-breaking IBC cell was fabricated at its State Key Laboratory (SKL) of PV Science and Technology (PVST), on a large-sized phosphorous-doped Cz Silicon substrate (156×156 mm) with a low-cost industrial IBC process, featuring conventional tube doping technologies and screen-printed metallization. Also, the move to market will be long as doesn’t have a commercial line producing this type of product. 3-5 years? Not worth waiting for with tax breaks/incentives/net metering being hacked at.

    Linking to this new website – Electrek.co – heard of it? Tesla battery researcher unveils new chemistry to increase lifecycle at high voltageIf made into a car battery pack, 1,200 cycles would translate to roughly 300,000 miles (480,000 km) – meaning that a battery pack could still retain about 95% of its original energy capacity after ~300,000 miles – or 25 years at the average 12,000 miles per year – If put in a house, the values would mean that you’d be above 80% of the batteries original capacity after 25 years. That’s a 25 year warranty on a battery pack coming! Game over.
