Résumé

An optimum amount of lead bromide (1%) can enhance the power conversion efficiency of CH3NH3PbI3-xBrx (where x approximate to 0) devices from 14.7% to 16.9% without altering the bandgap of the perovskite material.

Photovoltaic system

A photovoltaic system, also PV system or solar power system, is an electric power system designed to supply usable solar power by means of photovoltaics. It consists of an arrangement of several components, including solar panels to absorb and convert sunlight into electricity, a solar inverter to convert the output from direct to alternating current, as well as mounting, cabling, and other electrical accessories to set up a working system. It may also use a solar tracking system to improve the system's overall performance and include an integrated battery.

Photovoltaic system performance

Photovoltaic system performance is a function of the climatic conditions, the equipment used and the system configuration. PV performance can be measured as the ratio of actual solar PV system output vs expected values, the measurement being essential for proper solar PV facility's operation and maintenance. The primary energy input is the global light irradiance in the plane of the solar arrays, and this in turn is a combination of the direct and the diffuse radiation.

Centrale solaire photovoltaïque

thumb|Le Nellis Solar Power Plant comprend solaires PV sur (). Une centrale solaire photovoltaïque est un dispositif technique de production d'électricité renouvelable par des capteurs solaires photovoltaïques reliés entre eux (en série et en parallèle) et raccordé au réseau électrique par des onduleurs. Les centrales solaires sont de plus en plus puissantes (plus de en 2012), contrairement aux systèmes solaires photovoltaïques autonomes destinés à l'alimentation en électricité de bâtiments ou d'installations isolées (autoconsommation) dont la puissance dépasse rarement .
