Characterisation of carbon nanotube variability and application in solar cells
, 2011 Photovoltaic solar cells (PVs) are now recognised as the world’s fastest growing energy technology, yet, they only account for a mere fraction of current global renewable power capacity. It is acknowledged that this inadequate market penetration has been

Review of light-induced degradation in crystalline silicon solar cells
, 2016 Although several advances have been made in the characterization and the mitigation of light-induced degradation (LID), industrial silicon solar cells still suffer from different types of light-induced efficiency losses. This review compiles four decades

Autonomous Folding of Soft Matter From Living Polymers
Advanced Materials, EarlyView.Origami structures are endowed with “living” polymer creases that grow, remodel, and stiffen in response to nutrient solutions. This post‐fabrication growth enables autonomous folding, iterative regrowth, and mechanical tuning involving origami assemblies, such as cranes, Miura‐ori tessellations, rigid and non‐rigid square‐twist patterns, establishing ...

Solar Cells From Unpolished Silicon Wafers [PDF]
, 1976 Solar cells were made by diffusing impurities into the rough or backside of commercially available silicon wafers to form a junction. The properties of these solar cells were compared to solar cells made by diffusing impurities into the polished ...

Why perovskite solar cells with high efficiency show small IV-curve hysteresis
, 2017 There is increasing evidence that the presence of mobile ions in perovskite solar cells can cause a current-voltage curve hysteresis. However, it is still subject of ongoing debates how exactly mobile ions influence the device operation.
