Influence of TiO x and Ti cathode interlayers on the performance and stability of hybrid solar cells

Ligand-free preparation of polymer/CuInS2 nanocrystal films and the influence of 1,3-benzenedithiol on their photovoltaic performance and charge recombination properties

“…In previous studies, it was found that the long-term stability of ligand-free prepared polymer/CuInS 2 solar cells is very promising as the PCE of the investigated solar cells stayed almost constant over several hundreds of hours of constant illumination 16,43. To investigate if 1,3-benzenedithiol has a negative influence on the device stability, we also tested an encapsulated PPD–BDT/CuInS 2 solar cell under continuous illumination at maximum power point conditions.…”

Synthesis of a conjugated pyrrolopyridazinedione–benzodithiophene (PPD–BDT) copolymer and its application in organic and hybrid solar cells

“…However, it should be also pointed out that the V OC of 535 mV is the highest observed so far for in situ prepared polymer/CIS hybrid solar cells in which stable Ag electrodes are used instead of Al electrodes, which lead to limited lifetimes of the devices [19]. …”

“…The overall PCE of the hybrid solar cell is, however, despite the higher I SC , significantly lower than for the organic solar cell, because of the lower V OC and the lower FF and a value of 2.2% is obtained. However, it should be also pointed out that the V OC of 535 mV is the highest observed so far for in situ prepared polymer/CIS hybrid solar cells in which stable Ag electrodes are used instead of Al electrodes, which lead to limited lifetimes of the devices [ 19 ].…”

“…Using PSiF-DBT as conjugated polymer, PCEs of 2.8% could be obtained in combination with CIS nanocrystals [ 13 ]. In addition to conjugated polymers [ 17 ], also small molecular donors like p-DTS(FBTTh 2 ) 2 can be used as organic matrix [ 18 ] and the prepared solar cells exhibit good long-term stability [ 19 ]. Due to the low conversion temperature of the metal xanthates to the metal sulfide nanocrystals, in particular, if n -hexylamine is used as additive, also the preparation of flexible solar cells [ 15 ] and the fabrication of tandem solar cells [ 20 ] is possible using this in situ route.…”
