Why do solar cells have a measurement problem?
These measurement issues reflect the underlying physics occurring at JSC. Under these conditions, there is no photovoltage and the solar cell produces no power; the energy levels of the transport layers are short-circuited in the outer circuit and all of the electrical energy is being dissipated as current.
How are solar cells used?
The solar cells are connected with needle probes and the electrical measurements are made with a Keithley 2601 SMU. The assembly is also equipped with a TEC 2510 temperature controller. A reference cell is used to calibrate the lamp. One-sun measurements were carried out on cells ranging from 12.25 mm to 0.01 mm.
What are photoelectrochemical cells?
Photoelectrochemical cells (PECs) are solar cells based on a semiconductor–electrolyte interface. The ease of formation of this interface and the expectation that an interface between a solid and a liquid will be physically “perfect” led to considerable investigation of these cells after their appearance in the early 1970s.
How does a solar cell work?
Applying an external voltage to the solar cell results in the flow of current. Electrical transport of carriers to the electrodes can, in principle, be monitored with IS if the mobility is low and/or the carrier lifetime is long enough.
What are examples of electrochemical capacitance in solar cells?
Examples of commonly reported electrochemical capacitances in solar cells are the diffusion capacitance due to minority carrier transport in the vicinity of the depletion region, and chemical capacitance, due to carrier injection into a depleted or intrinsic semiconductor.
