Favorable federal tax policies and state regulatory reform could help the storage sector notch even higher rates of growth.

Thanks to a carbon dioxide doping technique, the solar cell interlayers exhibited conductivity around five times higher than that of a perovskite cell based on interlayers doped with oxygen. The device also showed an open-circuit voltage of 1.14 V, a short-circuit current density of 21.2 mA cm2 and a fill factor of 0.79. 

A U.S. scientist has developed a computational framework that assesses how well a hypothetical agrivoltaic project would perform in achieving desired outcomes such as the volume of PV electricity produced, and energy-to-agriculture. The method considers the high-frequency decomposition of solar irradiance into multiple rays and analyzes how these rays are propagated forward in time, to assess multiple reflections and absorption for various system configurations. It also takes into account panel inclination, panel refractive indices, sizes, shapes, heights, and albedo.

Backsheet failures have plagued the industry, causing hefty financial burdens to many asset owners. DuPont has launched a product it says allows for easy repair of modules.

NASA scientists have partially cleaned up the solar modules of the Insight lander operating on Mars, by using grain sands collected nearby and trickling them on the panels during the windiest time of the day. This handmade technique has made it possible, according to them, to increase the PV array’s yield of about 30 watt-hours of energy per ‘sol,’ or Martian day.

The solar cells for the space station were provided by Boeing’s subsidiary Spectrolab.

A group of researchers in the U.S. analyzed recent developments in efforts at dual land use projects, combining solar energy with habitat for pollinators and other wildlife. Based on recent projects and studies, they offer a list of best practices for developing the habitats; and warn that without careful oversight the promising concept could amount to little more than greenwashing.

Scientists at the US National Renewable Energy Laboratory have simulated a III-V solar cell by stacking gallium arsenide films onto interdigitated back contact silicon solar cells with a glass interlayer. The scientists have already done some initial mini-module integration work, but significant size scaling will ultimately be needed to reach commercialization. The cell currently has an active area of 1 cm2.

The “Gismo Power” solar carport is entirely mobile, can be connected to the grid, and can be folded for storage.

Here are three tools to help you navigate the sometimes-complex array of US state incentives for your rooftop solar project.
