Modules & Upstream Manufacturing

South Korean researchers have developed a hybrid tandem solar cell based on quantum dots and organic bulk heterojunction (BHJ) photoactive materials. They claim that the cell could reach an efficiency rate of around 15% if they continue to reduce energy losses in the quantum dot cell and enhance near-infrared absorption.

Fraunhofer ISE researchers have integrated stress and temperature sensors within a PV module. They claim that the devices cover a very minimal part of the cells, and that their interaction with the module and the cell itself is quite limited. The sensors can be manufactured as part of a regular cell manufacturing process.

Three more PV manufacturers are jostling to announce plans to invest in an expansion of production capacities as the industry appears to make light of coronavirus fears.

The Duomax V and Tallmax V panels are equipped with glass-glass and glass-backsheet frames, respectively. Both offer a reported 21% efficiency and orders will be taken from the second quarter on. Trina plans to have a combined 5 GW of annual production capacity for the products this year.

Researchers led by Belgian institute imec claim to have achieved the result with a 1cm² perovskite tandem solar cell. The result tops the 24.6% efficiency the consortium announced in September 2018. The cell’s developers are now aiming for 30%.

The Norwegian solar manufacturer is readying the 72-cell version of its Alpha Series heterojunction module for the factory floor.

With the European Commission claiming its €100 billion ‘Just Transition’ fund will ease EU coal mining regions into a post-fossil-fuel future energy system, Adam Smith considers what happened in one deprived area of Britain when government policy failed to support talk of clean energy ambitions.

Elon Musk has spoken of an ‘exponential’ ramp-up of its solar glass tile at the facility in New York state. Panasonic’s tiles never made the cut.

Researchers from China are proposing to use spent battery lead for creating a perovskite that can be used in the production of solar cells that are based on this promising material. The proposed one-step process, which was tested in the production of a 17.38% efficient perovskite heterojunction cell, is said to be cheaper and less energy-intensive than other recycling processes for waste lead from lead-acid batteries.

Researchers at the Italian oil group are trying to improve organic photovoltaics and luminescent solar concentrators and a new supercomputer with sophisticated algorithms will help them with the solar energy puzzle.
