Thin-Film Modules 101

solar frontier

Thin-film module from Solar Frontier. Typical thin-film solar modules resemble sheets of glass, as they consist of material placed between flexible laminate, steel or glass. Thin-film cells are made by depositing one or more thin layers of photovoltaic material on a substrate. These layers can vary in thickness from a few nanometers to tens of micrometers. A variety of thin-film... Read More

Photovoltaics 101

photovoltaic ft

Often called PV panels, these convert the energy of light (photons) into electrical energy as DC current. Panels come in variety of sizes but it is common to find them with 60 cells each with a power output of about 240 W. At this time, other variations include concentrated PV and thin-film solar. For PV panels, efficiency reaches to about 14%. Typical Structure of crystalline Silicon... Read More
