The black phase of formamidinium lead iodide (FAPbI(3)) perovskite shows huge promise as an efficient photovoltaic, but it is not favoured energetically at room temperature, meaning that the undesirable yellow phases are always present alongside it during ...
We suggest a new solar cell loss analysis using theexternal quantumefficiency (EQE) measured with sufficiently high sensitivity to alsoaccount for defects. Unlike common radiative-limit methods, wherethe impact of deep defects is ignored by exponential ext ...
Halide perovskites have gained tremendous attention over the past decade, but the poor stability of perovskite solar cells (PSCs) under operating conditions hampers their practical application. This thesis investigates materials that can be used to enhance ...
Solar cells based on metal halide perovskite and polymer donor:nonfullerene acceptor blend absorbers have recently witnessed a significant rise in their photovoltaic performance. However, they still suffer from some instability issues originating from the ...
Over the last few years, thanks to rapid development of molecular engineering and perovskite composition, it has allowed extremely promising solar energy conversion to achieve a certified power conversion efficiency (PCE) of over 25% for perovskite solar c ...
