Modules & Upstream Manufacturing

A research group in Ghana has conducted a series of tests to assess the performance of polycrystalline solar modules in PV systems operating in their home country for at least 5 years. They found that the vast majority of the panels may ‘fail’ before 20 years in operation under outdoor conditions.

In a new weekly update for pv magazine, Solcast, a DNV company, presents the solar irradiance data it collected for Europe in May. Below-average cloud cover meant above normal irradiation for much of the UK, France, Germany, the Baltics and Scandinavia, with anomalies as high as 30% and 40% above climatological means. Solar assets across Northern Europe will have overperformed on expectations for May.

CEA-INES researchers and Enel have developed a new solar cell with an active area of 9 cm² and an open-circuit voltage above 1,900 mV. Their results improve on the 26.5% efficiency they achieved for the same kind of cell in March.

In a new weekly update for pv magazine, OPIS, a Dow Jones company, provides a quick look at the main price trends in the global PV industry.

PV manufacturing capacity is projected to more than double by 2024, led by China, but oversupply is also anticipated, according to the International Energy Agency (IEA).

US researchers have designed a 2D solar cell based on TMDCs that may exceed by far the efficiency of this device typology, which usually doesn’t exceed 6%. The novelty of this cell consists of its superlattice structure, which the research group said can separate the layers of 2D TMDCs by a spacer, thus improving light absorption.

UK scientists have developed Solar2Water, a system that generates twice the amount of water as conventional atmospheric water generators. The system operates efficiently with the same energy input, regardless of air humidity, relying solely on photovoltaics.

NASA and SpaceX have successfully launched two new roll-out solar arrays, known as IROSA, to enhance the energy production capacity of the International Space Station’s microgravity complex. These arrays will provide an expanded and efficient power source for the space station’s operations.

A group of researchers and data scientists from the Chesapeake Conservatory studied the construction of solar energy facilities in states surrounding the Chesapeake Bay Watershed and found that solar developments on already cultivated land did not adversely impact biodiversity.

A research group from Ireland developed a PVT system consisting of a 170 W photovoltaic panel connected to a water tank placed at the backside of the PV module itself. The PVT module is able to considerably reduce the temperature of the PV unit while producing hot water for residential use.
