Scratching the surface of silicon in tandem solar cells
German scientists have investigated the role of surface texturing in perovskite-silicon tandem cells and have found that several new processes offer the ability to etch smaller, more uniform textures onto the surface of a silicon cell than today’s industry standard. This could help to ease the subsequent growth of a perovskite cell on top of the silicon, enabling researchers and manufacturers to target higher performance.
Slip-Slop and Slap it on everything, the ‘Solar Skin’ that doesn’t burn
Professor Guan Yeoh is an essential part of a project to commercialise a solar polymer membrane called ‘Solar Skin’, which can generate energy from both direct and indirect sunlight and off both vertical and horizontal surfaces. The technology has the potential to transform every CBD and local government area into a solar farm. pv magazine Australia sat down with Professor Yeoh for a Q&A.
