A solar bus or solar-charged bus is a bus that is powered exclusively or mainly by solar energy. Solar-powered bus service is referred to as a solar bus service. The use of the term "solar bus" normally implies that solar energy is used not only for powering electric equipment on the bus, but also for the propulsion of the vehicle.
New tariffs on Chinese electric vehicles and batteries, solar cells, medical equipment and other goods are intended to protect U.S. jobs and manufacturers. The tariffs will be phased in over the ...
For the past years, researchers have been trying to reduce the price of solar cells while maximizing efficiency. Thin-film solar cell is a cost-effective second generation solar cell with much reduced thickness at the expense of light absorption efficiency. Efforts to maximize light absorption efficiency with reduced thickness have been made.
Module and cell prices declined even further after 2014 (see price quotes in table). This price trend was seen as evidence supporting Swanson's law (an observation similar to the famous Moore's Law) that states that the per-watt cost of solar cells and panels fall by 20 percent for every doubling of cumulative photovoltaic production.

Solar cells operate by absorbing light, exciting the absorber. This creates electron–hole pairs that must be separated into electrons (negative charge carriers) and holes (positive charge carriers) by asymmetry in the solar cell, provided through chemical gradients [4] or electric fields in semiconducting junctions.

The 60 kWh battery version is expected to weigh about 1,800 pounds (820 kg), much lighter than most electric vehicles. [1] It has a NACS connector, and is able to charge at a rate of between 40 and 60 kW. [13] View of the solar panels throughout the vehicle
A direct plasmonic solar cell is a solar cell that converts light into electricity using plasmons as the active, photovoltaic material. The active material thickness varies from that of traditional silicon PV (~100-200 μm wafers) , [ 4 ] to less than 2 μm thick, and theoretically could be as thin as 100 nm. [ 5 ]
The mostly commonly researched modern photoelectrochemical cell in recent decades has been the Grätzel cell, although much attention has recently shifted away from this topic to perovskite solar cells, due to relatively high efficiency of the latter and the similarity in vapor assisted deposition techniques commonly used in their creation.
