Characterisation of loss mechanisms in hybrid trihalide perovskite solar cells — •Sebastian Reichert, Seth Niklas Schumann, Alexander Wagenpfahl, and Carsten Deibel — Fakultät für Naturwissenschaften, TU Chemnitz, D-09126 Chemnitz
Organic-inorganic trihalide perovskite solar cells belong to the most significant developments in the field of photovoltaics in the last years and seem to be a good bet at satisfying the need for high efficiencies and low manufacturing cost.
To take advantage of the potential of these hybrid solar cells, the loss mechanism which occurs within the active layer need to be understood. We therefore measure current–voltage characteristics for a range of perovskite (CH3NH3PbI3) solar cells with different processing parameters. We investigate the photoluminescence transients on corresponding thin films without electrodes. The loss mechanisms are modeled by fitting the obtained data to the continuity equation for excitons and charge carriers. We finally correlate the found recombination losses to the extracted solar cell parameters.
