Sun Power: Solar Panels

Sun Power is the current market leader in efficient solar energy modules, the conversion ratio of sun power solar panels is 19.3%, among which Sanyo is having the most efficient modules at 20.4%. How so ever, a whole range of other companies like Holo Sun, Gamma Solar, Nano Horizons are also emerging which are offering new creations in photovoltaic modules, having a conversion ratio of around 18%. These new creations involve power generation on the front and back sides as well as increased outputs; yet, most of these companies have not produced working systems from their strategy plans, and are mostly still working in order to improve the technology.

This solar panel is used as a component in a larger photovoltaic system to provide electricity for marketable and residential applications.
As we know a single solar panel can only produce a finite amount of power, many installations hold several panels. This is called as a photovoltaic array. An array of solar panels is typically included in a photovoltaic installation, an inverter, batteries and interconnection wiring.
Solar cells are usually electrically connected and encapsulated as a module. Photovoltaic modules usually have a sheet of glass on the front side, which allow light to pass while protecting the semiconductor wafers from the elements like rain, hail, etc. Solar cells are also usually connected in series in modules, creating an additive voltage. A higher current will be yielded if the cells are connected in parallel. Hence, these modules are interconnected in any way that is series, parallel or both to create an array with the wanted peak DC voltage and

When the electron diffusion occurs across the p-n junction, they combine with holes on the p-type side. The carrier diffusion does not happen indefinitely as charges build up on either side of the junction and an electric field is created. This electric field creates a diode that helps in promoting charge flow which is called as drift current, that opposes and eventually balances electron and holes diffusion. The region where electrons and holes have diffused across the junction is known as the depletion region as it no longer contains any mobile charge carriers. It is also called as the space charge
