MIT, NREL researchers develop 40%-efficient thermophotovoltaic cell for grid-scale thermal batteries

The device is described as a heat engine with no moving parts that is able to produce power from a heat source of between 1,900 to 2,400 C. This concept is known as thermal energy grid storage (TEGS) and consists of a low-cost, grid-scale storage technology that uses thermophotovoltaic cells to convert heat to electricity above 2,000 C.

Growatt unveils solar rechargeable portable power station

Chinese inverter maker Growatt has launched Infinity 1500, a portable power station for off-grid applications.

Polysilicon maker predicts 5-year shortage of solar raw material

TBEA-owned Xinte Energy says it cannot produce polysilicon quickly enough to meet demand and wants shareholders to back its bid to quadruple its manufacturing capacity by mid 2024.

India calls for credit guarantee fund to drive solar adoption in electricity-deprived regions globally

RK Singh, India’s power minister, and president of the International Solar Alliance (ISA) Assembly, called on nations to support solar investments in developing and under-developed regions, including Africa, through low-cost finance and credit guarantee fund.

New solar module cooling tech based on porous nanochannels

US scientists have utilized a nanochannels device to cool down the operating temperature of a commercial PV module and have found that the proposed technique is able to improve power yield by up to 32.8%. Spray droplets are dispersed over the nanochannels device in order to eliminate the need for a continuous supply of a coolant.

Zinc-ion battery for residential applications

Developed by Canadian start-up Salient Energy, the zinc-ion battery has a rated capacity of 60 Ah, a nominal voltage of 1.3 V, and a volumetric energy density of 100 Wh/L. The device measures 26cmx24cmx1.2cm and weighs in at 1.3 kg

The long read: Defining the performance of bifacial solar modules

or some developers of ground-mounted PV, bifacial modules are already the default technology. The slight cost increase is often outweighed by an increase in energy yield. And yet “agreeing” on the right energy yield of a PV plant has always been the most heated debate between developers, investors, lenders, and technical advisers. Everoze partner Christophe Campistron looks at both sides.
