PV Technology

Semiconductors which are essentially silicon based devices or cells that convert sun light to electricity directly are called Solar Photovoltaics (SPV). The silicon employed in the SPV cells is crystalline in nature. Crystalline silicon is further classified as single crystal (sc-Si) which is also referred to as monocrystalline and poly or multicrystalline (mc-Si). These crystalline silicon based cells which have nearly 90% market share of the commercially deployed modules and arrays.

BioFuels

With skyrocketing price of crude fossil fuel (oil) which is currently hovering around $102/barrel, there is renewed interest and a sense of urgency in biofuels in many developing countries as a means of “modernizing” biomass use and providing greater access to clean liquid fuels while helping to address energy costs, energy security and global warming concerns associated with petroleum fuels.

QC/QA of Cells & Modules

Solar industry will continue to experience explosive growth at least for the next decade or more. With increased affordability and adaptability of solar applications in residential and commercial, and state and local mandates, the need for a quick and reliable series of tests and measurements has intensified to ensure quality of cells and modules. Solar cells and modules are manufactured in a multitude of power levels and various conversion efficiencies. Research, Production, and QC/QA have different needs for measurement, accuracy and range of parameters that must be measured. The manufacturing of cells and modules can be classified into two distinct processes.
