Rooftop photovoltaic power station Rooftop photovoltaic power station A rooftop photovoltaic power station, or rooftop PV system, is a photovoltaic system that has its electricity-generating solar panels mounted on the rooftop of a residential or commercial building or structure. The various components of such a system include photovoltaic modules, mounting systems, cables, solar inverters and other electrical accessories. Rooftop mounted systems are small compared to ground-mounted photovoltaic power stations with capacities in the megawatt range. Rooftop PV systems on residential buildings typically feature a capacity of about 5 to 20 kilowatts (kW), while those mounted on commercial buildings often reach 100 kilowatts or more.
Third-generation photovoltaic cell discovered center around nanotechnology, there are several different material methods currently used. The third generation label encompasses multiple technologies, though it includes non-semiconductor technologies (including polymers and biomimetics), quantum dot, tandem/multi-junction cells, intermediate band solar cell, hot-carrier cells, photon upconversion and downconversion technologies, and solar thermal technologies, such as thermophotonics, which is one technology identified by Green as being third generation. It also includes: Solar cells using MEV-PPH and CdSe variable particles trapped in polymer by Arvind Kumar Singh-scholar from NIET Greater Noida.
