In the 100th volume of Applied Physics Letters Carr and Chaudhary have presented a work on capacitance characterization of organic photovoltaic cells. The work concerns small signal measurements of various organic photovoltaic structures. The authors however limit their considerations to one part of small signal response, namely to capacitance measured either in parallel mode or in series mode. This attitude generally does not lead to accurate capacitance in organic devices and only for certain cases can result in appropriate values. Moreover, confusing C’’ with C’ they classify our work into “improper” models. In this comments, we go into details of capacitance characterization of organic photovoltaic cells and we rectify a mistake which appear in Carr and Chaudhary’s work.
