Solar Photovoltaics (PV) Technology


PV is a field of diverse innovative activity, from the solar modules in the DC segment to grid interfacing electronics on the AC side.The technology achievements to date, and further progress taking place, cover more than just LCOE reductions e.g.:

-          Reactive energy injections to stabilize and enhance grid performance

-          Trackers to deliver greater and more evenly distributed output

-          Advanced monitoring systems, including atmospheric models

-          Hybrid combinations with other energy sources to optimally match demand

-          Floating PV systems

-          Performance in harsh environments, varying light conditions

-          Cell designs to harvest albedo light

-          Efficient materials utilization


The speed and breadth of innovation shows the massive scope for improving PV systems: offering further cost reductions and new value-adding functionality.


The single most expensive component of a PV system is the solar module.Solar modules consist of interconnected cells - semiconductor sandwiches - the electricity generation units of a PV system.The current market is dominated by single-junction cells made of multi- or mono-crystalline silicon. Out of the thin-film contenders, the cadmium telluride technology of Frst Solar is the most successful.A number of commercially available single-junction solar cells can now exceed 20% power conversion efficiencies at standard testing conditions. The achievable efficiencies are much higher for multi-junction cells, can be doubled to over 40% but the challenge is to accomplish it with a low-cost Bill-of-Materials and industrially scalable manufacturing.
