The record efficiency was obtained thanks to an interlayer placed between the electron-transporting layer and the perovskite layer, which eliminated the need for passivation. The cell was also able to retain around 90% of its initial efficiency after 500 hours under standard illumination.

Sydney-based 5B has taken the wraps off a new generation of its re-deployable modular Maverick solar technology which it says is not only quicker and easier to install than the previous model but 30% more powerful.

A collaboration between universities, nonprofits, and a geospatial mapper led to development of a highway solar evaluation tool.

Scientists in South Korea demonstrated a fabrication technique for perovskite solar cells relying entirely on room temperature, ambient conditions processes. Using an all-inorganic perovskite material, and a spray coated electron transport layer, cells fabricated by the group achieved a maximum efficiency of 19.75%.

This week saw prices in the polysilicon segment, and further downstream, rise again, with no end in sign. National Energy Agency statistics show a slowdown in installations for the second consecutive month in September. Manufacturers, however, continue to purchase components and materials in the expectation that prices will rise even further.

Participating companies and industry experts from Spain’s most recent renewable energy auction, including APPA, Anpier, and Fundación Renovables, share their thoughts with pv magazine on the results published this week, and what could be done better in future tenders.

Energy consultancy DNV was tasked by module manufacturing giant Longi Solar with comparing the balance of systems costs between modules utilizing 182mm and 210mm wafers, based on a 3.7 MW project in three different layouts. The results reveal a slim cost advantage for the smaller of the two, based on both fixed tilt and tracker systems.

In a bid to enhance ratio of emissions-free generation in its energy mix, the Bangladesh government is condsidering replacing small-sized oil-fired power plants with new nuclear.

PV manufacturing giant Trina Solar says it has agreed with other industry players on a set of standard dimensions and other technical specifications for PV modules utilizing 210mm wafers – the largest currently available on the market. The manufacturer says it expects the China Photovoltaic Industry Association to formally release the standard before the end of October.

Spain’s latest renewable energy auction has awarded 3.12 GW of new capacity at an average price of €30.56/ MWh. Capital Energy once again took the largest share, winning all of 1.548 GW that it was competing for, in an auction where the absence of some large power companies was conspicuous.
