Voltskin

Voltskin is a photovoltaic coating — a solar paint, supplied in gel form — that turns ordinary surfaces into electricity-generating ones. The material uses nanomaterials including calcium titanate, titanium dioxide and zinc oxide, coated with semiconductor quantum dots, and is paired with a collector device built around ultra-fast-charging supercapacitors that store the captured energy.

The material has been examined by the Department of Analytical Chemistry at the University of Granada, which recorded energy-conversion efficiency above 11 per cent and issued a declaration of interest in collaborating on industrialising the process. The department reported that the coating adheres permanently to plastics, fabric, wood, metal and concrete, carries a service life of fifteen to twenty years, and has an installed cost per square metre on average roughly twelve times lower than conventional panels.

A separate inspection by TÜV SÜD Iberia, with Euro G-Sat, assessed the electrical and physical properties of two gel samples and their collector and returned a satisfactory result with no deviations. Together the assessments describe a low-cost, durable and environmentally benign route to distributed solar generation on surfaces where conventional panels cannot practically be installed.
