In general, an increase in absorber thickness can result in higher values for two key parameters of the solar cell: short-circuit current and open-circuit voltage. This increase is attributed to the greater absorption of solar light by the solar cell, leading to a higher generation of charge carriers.
High efficiency solar cells are designed by finely tuning the variables such as thickness and doping density of the hole transport layer (HTL) and the absorber layer through device simulation. Our findings are presented in Section 3. The simulation was conducted using wxAMPS-1D simulation software program, an updated version of AMPS-1D.
Specifically, it is observed that Voc and FF decrease as the thickness increases, primarily due to the rise in series resistance. In general, an increase in absorber thickness can result in higher values for two key parameters of the solar cell: short-circuit current and open-circuit voltage.
Consequently, IS allows for the identification and quantification of various factors contributing to the resistance of the solar cell, including electrode resistance, the p-n junction, and the hole and electron transport layers. Moreover, IS can serve as a valuable tool for monitoring the operational state of solar cells.
