The Korea Institute of Energy Research has developed a 3kW solar noise barrier to produce electricity and heat. The thermal solar modules reduce the operating temperature of the photovoltaic panels by absorbing excess heat.

A British-Indian research group has developed an active cooling technique that is claimed to improve a PV system’s yield by around 0.5%. The system could be used in residential solar arrays and the water heated by the PV modules may be fed into a solar water heating system.

The solar cell was built with Al2O3-incorporated CZTSSe absorbers using aqueous spray pyrolysis in ambient air. It achieved an open-circuit voltage of 0.469 V, a short-circuit current of 36.96 mA cm2, and a fill factor of 67.25%.

Australian solar window supplier ClearVue says its products can reduce carbon emissions in buildings by as much as 90%, while California-based BIPV window coating producer Ubiquitous Energy has raised $70 million to scale up its own tech.

Jiangxi Jinko plans to issue 2 billion shares at RMB5.00 per share and expects to raise net proceeds of around RMB 10.0 million. Solar manufacturer Solargiga said it expects a 17% revenue growth for 2021.

The companies will collaborate on what is believed to be a first-of-its-kind attempt to incorporate QuantumScape’s solid-state lithium-metal battery technology into stationary energy storage products.

Lithuanian scientists built the panel with 23.9% efficient solar cells with operational stability of over 1000 h. The module has an active area of 26 cm2.

The device has a 4-in-1 design, which means it can be connected with four solar panels with a power output of up to 625 W each, through four independent connections. The output of each panel is tracked and converted individually. According to the Chinese manufacturer, the micro-inverter can ensure savings of up to 50% due to the lower number of devices and cables needed.

The new heterojunction module series is compatible with Panasonic’s Evervolt battery and has a power output ranging from 400 to 410 W. It also features a temperature coefficient of -0.26% per degree Celsius.

Local planning committees have given a go-ahead to a £2.5 billion gigafactory in the English West Midlands. The facility will be powered by 100% onsite solar and storage and equipped to both manufacture new batteries and recycle used ones.
