Solar Technology & PV R&D News

The weight of a thin-film rooftop PV installation at Netherlands football club AZ Alkmaar has been highlighted in media reports as a possible cause of a stadium roof collapse. However, a full investigation is yet to be launched and one German specialist said studies have shown flush-mount PV panels do not increase static wind loads on rooftops.

By considering use of the metal in charging infrastructure, analyst Wood Mackenzie has found higher demand from the mobility sector than is the case if only the volume of the material required for vehicle construction is examined.

Researchers in the US have published a study that brings 20 years of renewable energy (solar PV and/or wind plus storage) generation into line with historical energy-demand profiles, to ascertain at what storage cost point renewables can cost-effectively consistently meet 100% demand.

A U.S. research team has found the most efficient locations for agrivoltaics include western America, southern Africa and the Middle East. The researchers found crop land, grasslands and wetlands were the best environments for PV projects linked to agriculture. Conditions suitable for crops are ideal for improving solar module efficiency.

Michael van der Gugten, Sales and Marketing Executive at Smit Thermal Solutions, is convinced that perovskite solar cells have reached maturity, and that they are ready to make the step from the lab to production. He is leading the organization of a conference on this topic and expects that the perovskite community, production equipment suppliers and crystalline silicon cell manufacturers will discuss the implementation of perovskite-silicon tandem cells or the production of standalone perovskite modules.

Researchers at the University of Massachusetts Amherst’s College of Information and Computer Sciences (CICS) have developed a method for automatically assessing rooftops for solar potential.

Chinese thin film producer Hanergy has set a new record of 24.85% module efficiency for silicon heterojunction technology. The record was achieved at the company’s research & development center in Chengdu, China, and has been confirmed by the Institute for Solar Energy Research in Hamelin, Germany.

The MNRE has invited proposals for high-efficiency perovskite solar cells, solar panel recycling, hybrid inverters and new applications that combine solar and storage, among others.

The researchers have developed a new manufacturing process by using an ultra-thin absorbing layer made of 205-nanometer-thick gallium arsenide (GaAs) and a nanostructured back mirror.

The industrial development of the bifacial solar module over the last few years represents one of the most significant events in the world of photovoltaic systems. Today, this technology constitutes one of the most promising trends in the global solar market. During Intersolar South America, Convert will present its bi-facial tracker, an innovative solution to gain more solar energy from the panels.

Students from Western Sydney University has unveiled its latest solar racing car that it intends to enter in the gruelling 3,000km World Solar Challenge from Darwin to Adelaide through Australia’s searing heat this October.

Hyundai has released a version of its Sonata hybrid that has solar panels to help charge its battery.

Railway operators can now feasibly connect solar plants to traction substations, claims a consortium that is now working on a similar demonstration project in the U.K. Almost all of the 30 kW installation’s output will be used to move trains, but in the future storage could come into the picture for larger “railway-connected” solar power projects, says 10:10, the U.K.-based climate change charity that developed the pilot.

According to a new report by BNP Paribas Asset Management, renewables offer more advantages than simply mitigating climate change. Electricity is easier to transport than oil, and wind and solar electricity prices are much more stable than volatile oil prices. An analyst from the French bank argues that major producers will need to reduce oil prices below $20 to compete with clean energy in the transport sector.

New textile-based solar cells developed by Fraunhofer researchers, semitrailers could soon be producing the electricity needed to power cooling systems or other onboard equipment. In short, textile-based solar cells could soon be adding a whole new dimension to photovoltaics, complementing the use of conventional silicon-based solar cells.
