The Energy Collection
This solar glassware collection is constantly at work: whether you’re drinking from your glass or have it resting on a table, it’s gathering energy from the light that surrounds it.
Each glass object comes with integrated solar cells, and when put away in their specially designed cabinet, the energy is transferred and collected in the structure. The cabinet then functions like a battery, through which you can charge and power your appliances indoors.
Within each piece of glassware is a photovoltaic layer of Dye Sensitised Solar Cell (DSSC). In these cells, properties of colour are used to create electrical currents of varied strength. Each colour has a unique wavelength and collects different currents; for example, purple is more efficient than blue.

This solar glassware gathers energy from the light around it. Whether you are drinking from your glass or have left it on the side, it is constantly working to gather energy. The solar cells are completely integrated into the objects themselves, a unique
self-sufficient system. When you put the glass away, the specially designed cabinet itself collects and stores this energy; it’s a way to gather and harvest energy all within one room. The cabinet works as a battery; this power can be adapted in many ways, from charging your phone to powering a light source.
Within each glass is a photovoltaic layer of Dye Sensitised Solar Cell. This means that the properties of colour are being used
to create an electrical current. This technology was invented by Michael Graetzel at EPFL. It is a technique based on the process of photosynthesis in plants.
Like the green chlorophyll which absorbs light energy, the colours in these cells collect energy. The glassware uses sunlight as a sustainable source of energy, but can also work under diffused light. This makes them much more efficient for use inside the home compared to standard solar panels, which only work in direct sunlight and are not suitable for indoor use. Different colours mean different properties. Each colour has a unique wave length and collects different currents. For example, blueberries and raspberries have their own voltages and levels of efficiency according to the colour spectrum.
