The main challenges for the commercialization of the PERL solar cell were the dielectric passivation, local contact opening, and the local doping. The solution for the local doping was already presented in 1989 by Knobloch et al. who showed that aluminium alloying could be used instead of boron diffusion for the localized contacts, which significantly simplified …
Solar Power: How Solar Energy Works Step by Step
The key players in this process are solar panels consisting of solar cells that absorb sunlight. Within these cells a dance occurs – electrons become excited and start moving around. This movement generates energy and by utilising an inverter, we can transform this energy into a form that powers our homes, appliances, and even some vehicles.
