Name

Transient Photocurrent Response

Outline

A recipe to obtain Transient Photocurrent by applying bias light and measuring Transient Photocurrent Response while irradiating pulsed light when the solar cell is short circuited. The photocurrent is measured in a predetermined time period immediately after the pulsed light irradiation, the measured photocurrent value is plotted as a function of time, and the value of the exponential decay constant is automatically extracted from the transient photocurrent measurement data, and the transient extracts the charge collection time of the solar cell from the response characteristics.

Transient Photovoltage Response

Outline

A recipe to obtain Transient Photovoltage by applying bias light and measuring Transient Photovoltage Response while irradiating pulsed light when the solar cell is open circuited. The photovoltage is measured in a predetermined time period immediately after the pulsed light irradiation, the measured photovoltage value is plotted as a function of time, and the value of the exponential decay constant is automatically extracted from the transient photovoltage measurement data, and the transient extracts the charge life time of the solar cell from the response characteristics.
