Value of solar
Value of solar (VoS) is a method of compensating distributed solar generation at its calculated benefit to the utility and society rather than at the retail rate.
Van der Waals heterostructure photovoltaic
A van der Waals heterostructure photovoltaic is a solar cell whose junction is made of stacked atomically thin 2D materials held by van der Waals forces.
Vehicle-integrated photovoltaics
Vehicle-integrated photovoltaics (VIPV) are photovoltaic modules embedded in vehicle body surfaces such as the roof and hood, generating electricity on board to support propulsion or reduce grid charging.
Wide-bandgap perovskite
A wide-bandgap perovskite is a metal-halide perovskite absorber with a bandgap of roughly 1.65 to 2.0 eV, serving as the high-voltage front cell in tandem solar cells.
Wide-bandgap perovskite solar cells
Wide-bandgap perovskite solar cells are photovoltaic devices based on mixed iodide-bromide perovskites with bandgaps above 1.7 eV, serving as the top subcells of perovskite/silicon tandems that have reached about 35% efficiency.
Wire interconnect
A wire interconnect is a photovoltaic module technology, commercialized as SmartWire Connection Technology (SWCT), that replaces flat solder-coated copper ribbons with thin round wires, cutting shading and silver use.
XBC
XBC is an umbrella term for back-contact silicon solar cell technologies that place both electrodes on the rear in an interdigitated pattern, eliminating front grid shading.
Y-series non-fullerene acceptors
Y6-series non-fullerene acceptors (Y-series NFAs) are small-molecule electron acceptors for organic solar cells, introduced in 2019 and driving efficiencies from about 13% to past 19%.
Z-source inverter
A Z-source inverter is a power electronic converter using an X-shaped network of two inductors and two capacitors to buck and boost voltage in a single stage.
Zinc oxysulfide buffer layer
Zinc oxysulfide buffer layer, written Zn(O,S), is a thin cadmium-free n-type semiconductor film used as the buffer layer in CIGS thin-film solar cells, with a band gap tuned by its oxygen-to-sulfur ratio.
Zola Electric
Zola Electric, originally named Off Grid Electric, is a solar energy company founded in Tanzania in 2011 that pioneered pay-as-you-go solar home systems paid through mobile money.
