The reported photocurrent density (J(SC)) of PbS quantum dot (QD)-sensitized solar cell was less than 19 mA/cm(2) despite the capability to generate 38 mA/cm(2), which results from inefficient electron injection and fast charge recombination. Here, we report on a PbS:Hg QD-sensitized solar cell with …

We study charge recombination via triplet excited states in donor/acceptor organic solar cells and find that, contrary to intuition, high internal quantum efficiency (IQE) can be obtained in polymer/fullerene blend devices even when the polymer triplet state is significantly lower in energy than the …
Next-generation applications for integrated perovskite solar ...
Photocurrent spectroscopy examines the photocurrent produced by an electrochemical cell as a function of wavelength of the incident light. The optical bulk band gap of the semiconductor electrode can be determined along with information about whether it is a direct or indirect transition.
This paper presents the results of our experimental study of high resolution map of induced photocurrent in monocrystalline silicon solar cells.

As a result, the spectral radiative heat flux that you have obtained for your NFTPV system will have a unique distribution that is tailored to the specific properties of your thermal emitter and the gap distance between the emitter and the TPV cell. The TPV cell''s ability to generate photocurrent will therefore be directly related to this near ...
