Third-generation photovoltaic cellThird-generation photovoltaic cells are solar cells that are potentially able to overcome the Shockley–Queisser limit of 31–41% power efficiency for single bandgap solar cells. This includes a range of alternatives to cells made of semiconducting p-n junctions ("first generation") and thin film cells ("second generation"). Common third-generation systems include multi-layer ("tandem") cells made of amorphous silicon or gallium arsenide, while more theoretical developments include frequency conversion, (i.e.
Panneau photovoltaïque thermiqueUn panneau photovoltaïque thermique (PV-T), ou panneau solaire hybride, ou encore panneau aérovoltaïque est un dispositif conçu à la fois pour produire de l'électricité photovoltaïque et pour recueillir l'énergie thermique provenant du Soleil.
Soiling (solar energy)Soiling is the accumulation of material on light-collecting surfaces in solar power systems. The accumulated material blocks or scatters incident light, which leads to a loss in power output. Typical soiling materials include mineral dust, bird droppings, fungi, lichen, pollen, engine exhaust, and agricultural emissions. Soiling affects conventional photovoltaic systems, concentrated photovoltaics, and concentrated solar (thermal) power. However, the consequences of soiling are higher for concentrating systems than for non-concentrating systems.
Système d'alimentation autonomevignette|320x320px| Schéma d'un système hybride Un système d'alimentation autonome (SAA, ou ), ou plus précisément un système d'alimentation électrique autonome également connu sous le nom d'alimentation électrique en zone éloignée, est un système électrique hors réseau pour les emplacements dépourvus de réseau de distribution d'électricité. Les SAA typiques incluent une ou plusieurs méthodes de production d'électricité, de stockage d'énergie et de régulation.
Solar cell researchThere are currently many research groups active in the field of photovoltaics in universities and research institutions around the world. This research can be categorized into three areas: making current technology solar cells cheaper and/or more efficient to effectively compete with other energy sources; developing new technologies based on new solar cell architectural designs; and developing new materials to serve as more efficient energy converters from light energy into electric current or light absorbers and charge carriers.
