Mascotte Industrial Associates has submitted a new backpack that incorporates thin film solar cells dye sensitized. These backpacks are lined with layers of this type of solar cells which are flexible, lightweight, and low cost and they will recharge electronic devices as we move. With these packs we could recharge the phone without needing a nearby power point.

The solar cells manufactured by G24 Innovations, are based on semiconductor nanocrystals coated with a layer of dye. The dye absorbs light and creates electrons which are transmitted to the semiconductor and then to the circuit.

These solar cells have a lower efficiency than the best thin film solar cells but they have in advantage that they are significantly cheaper and they can be printed on flexible surfaces.

In addition, dye-based cells operate in a wide range of angles; they have a long durability and they are effective indoors, because the dye is poorly absorbed by diffuse sunlight and fluorescent light.

  3. Great Idea! I would also add that this would be a great safety device for back country backpackers and hiking enthusiasts. GPS systems could remain charged for long trips into the wilderness. I doubt that some cell phones would benefit as there would be no towers in range. They could also charge small computers and range finder gadgets. Not just for school kids!

  4. State, local and federal goverments should make larger investments in promoting renewable energy projects. Perhaps if consumers spend money in this area, our government will begin to do so as well.

  5. We should all be looking at the environment and what we can do to help the situation. It’s great that you are promoting solar energy and its be benefits. Products like this are inovative and the future.
    Keep up the good work
