Thin film solar cells
“How can we make solar cells that are 350 times smaller than average?”
Most traditional solar panels rely on crystalline technologies for their embedded framework. However, is there a different way to manufacture solar cells altogether, and what are the side effects? Well, let’s use our engineering mindset to build this new technology. We know, that the beating heart of every solar panel is the semi-conductor technology that converts light into energy. So what if we were to take a thin layer of small semi-conductors (such as cadmium-telluride[CdTe], and then deposit it onto a transparent substrate material such as metal, plastic, or glass? This is the operating principle behind thin film solar cells, whose manufacturing process results in a cheaper, smaller (around 350 times smaller in thickness) and flexible build but less efficient and heat resistant as well.
