Scientists at European solar research organization, Solliance have announced the achievement of 14.5% conversion efficiency on a perovskite module. The module uses a glass substrate, and the efficiency was measured on an aperture area of 144 cm².

Scientists from the University of Wollongong in Australia have developed battery cells based on sodium-ion technology which the university says can achieve excellent cycling stability and easily be scaled up to mass production.

Together with Austrian equipment manufacturer EVG, Fraunhofer ISE has achieved an efficiency of 33.3% on a multi-junction solar cell. The highlight of the cell is the ultra-thin II-V semiconductor layer. However, it will be a few years before mass production is possible.

Although current efficiencies for solar cells based on kesterite do not exceed 12.6%, the use of germanium may enable the development of cells with a higher energy band gap.

The group of scientists has identified a new process by which holes get trapped in nanoparticles made of zinc oxide.

Dr. Frank Rijsberman, Director-General, Global Green Growth Institute (GGGI), South Korea, speaks to pv magazine about its ventures in the Indian solar and storage market. Rijsberman outlines that the country’s growing and diversifying economy, with its ambitious renewable targets, can help to capitalize on the demographic dividend. As a result, it can become the world’s primary consumer sustainable growth market.

Japanese electronics giant Sharp has announced the achievement of 25.09% conversion efficiency, from a cell utilizing both heterojunction and back contact technology. The measurement has been validated by Japan Electrical Safety & Environment Technology Laboratories (JET).

Scientists from the Solar Energy Research Institute of Singapore (SERIS) have announced the development of a new wet chemical process to allow multi-crystalline Si wafers to be cut with diamond wire saw technology, and subsequently textured to reduce their reflectivity.

Lamination innovation: The ongoing ambition of laminator manufacturers is to develop machines that can deliver high output through a faster lamination process, while simultaneously reducing their footprint by combining several machines into one. However, an in-depth process know-how is essential in order to produce defect-free modules. Which players possess such knowledge?

Scientists led by Cambridge University have discovered that adding a simple solution of potassium to the ink solution has the effect of ‘healing’ defects in metal-halide perovskite films, and immobilizing ion movement. This, according to the researchers, could push the material to higher efficiencies, while also increasing its stability.
