Solar Photovoltaic (PV) Technology Introduction

Solar makes great financial sense!

The typical solar PV cell structure contains n-type and p-type layers that form a p/n junction that causes electrons to move from one layer to the next, creating an electrical current in the process. The layers are encased with front and back contacts to capture the electron flow and protected by glass and an anti-reflective coating. Currently, most PV cells are manufactured on a silicon substrate. The PV process takes place whenever sunlight is present and operates safely and passively with no moving parts.
