Turkey’s new provisions state that self-consumption projects and solar irrigation installations can be built without the need for construction permits.

Mitsubishi Power Americas and Magnum Development are set to begin construction on a 300 GWh underground storage facility in the US state of Utah. It will consist of two caverns with capacities of 150 GWh, to store hydrogen generated by an adjacent 840 MW hydrogen-capable gas turbine combined cycle power plant.

Scientists in Bangladesh have investigated the potential of agrivoltaics in rice fields. They analyzed the economic viability of bifacial agrivoltaic projects in Vietnam, Bangladesh, China, Egypt, Brazil, and India.

Japanese scientists have built a chalcopyrite PV device for tandem solar cells and water splitting for hydrogen generation. The device has a power conversion efficiency of 11.05%, an open-circuit voltage of 0.960 V, a short-circuit current density of 15.9 mA cm−2, and a fill factor of 72.4%.

France’s new tariffs range from €0.1951 ($0.1984)/kWh for installations below 3 kW in size to €0.1068/kWh for arrays ranging in capacity from 100 kW to 500 kW.

Israeli researchers have developed a device that combines a reversible Si anode with halide cathodes and uses hybrid electrolytes to enable cell recharging. In the proposed system configuration, silicon is dissolved during the battery discharge process, and upon charging, elemental silicon is deposited.

A US-Chinese research group has built a perovskite solar cell with a hole-transporting material (HTM) based on conducting polyaniline (PANI) polymer. The device showed significantly higher efficiency than a reference solar cell relying on an HTM made of commonly used PEDOT:PSS.

Tongwei was followed by Aiko Solar, Runergy, Solar Space and Jietai Technology. The top five cell manufacturers supplied a total of 59 GW.

The transaction is part of KKR’s expansion strategy in the renewable energy sector.

An international research group has reconstructed the trajectory of p-type wafers in the heterojunction solar cell segment and has identified the lack of knowledge about boron-oxygen related light-induced degradation (BO-LID) as the main cause for the limited adoption of these wafers and the success of their n-type counterparts. According to the scientists, however, there is still big room for improvement for p-type technologies in heterojunction cells.
