Corporate Responsibility and Sustainability News: Spray-on Solar Panels?
This is the first of these solar-electric vehicles to hit the market, but with the success of vehicles like Tesla Motors ‘ Model S, I would be surprised if we didn’t see more. Earlier this year, I calculated that even a small 300-watt array on the roof of a Model S — the same size as C-Max Energi’s array — could provide over 2,000 miles of range without plugging the vehicle in. If cells are added to more than the roof, that figure could rise to over 5,000 miles of range from on-board solar. Right now, solar cars racing across the country show just how much potential there is for solar in the auto industry, especially now that electric vehicles are taking off. If automakers can begin incorporating some of the same technology into commercial vehicles, it will not only save EV owners from going to the pump, they’ll be able to charge up without plugging in. Not only are SunPower’s cells more efficient than competitors, the construction allows for an all-black design that improves aesthetics when applied to a car. Source: SunPower. Who will benefit from solar cars To see who would benefit most from cars going solar, all you have to do is look at the 23 cars that entered the American Solar Challenge.

Efficient organometal halide perovskite based photovoltaics were first demonstrated in 2012. They are now a very promising new material for solar cells as they combine high efficiency with low materials costs. The spray-painting process wastes very little of the perovskite material and can be scaled to high volume manufacturing similar to applying paint to cars and graphic printing. Lead researcher Professor David Lidzey said: “There is a lot of excitement around perovskite based photovoltaics. Remarkably, this class of material offers the potential to combine the high performance of mature solar cell technologies with the low embedded energy costs of production of organic photovoltaics.” While most solar cells are manufactured using energy intensive materials like silicon, perovskites, by comparison, requires much less energy to make. By spray-painting the perovskite layer in air the team hope the overall energy used to make a solar cell can be reduced further.
