Good light harvesting properties and matched energy levels as well as enhanced Jsc value and high Voc value in solar cells were achieved simultaneously by construction of the D–A–π–A type regular terpolymers of PIDT-DTQ-TT, finally leading to the maximum PCE value of 6.63% in PSCs.

We found that inserting silver nanoparticles (AgNPs) between two layers of reduced grapheme oxide (rGO) has an effect on tailoring the work function of rGO. The utilization of rGO/AgNPs/rGO sandwich structure as the hole extraction layer in polymer solar cells is demonstrated. Solution-processable fabrication of this sandwich structure at the ITO/active layer interface facilitates the extraction of hole from active layer into ITO anode because of lowering the barrier level alignment at the interface. It results in an improvement of the short circuit current density and the overall photovoltaic performance.

The degradation of the performance of the polymer solar cell based on the blend structures system of poly (3-hexylthiophene) (P3HT) and [6,-phenyl C61-butyric acid methyl ester (PCBM) is investigated. This study uses UV-vis absorption spectra, photoluminescence (PL) spectra, charge-transport dark J-V curve chart to explicate the reason for the degradation of the performance of P3HT:PCBM photovoltaic cells. Solar cell performance is degraded primarily through loss in short-circuit current density (Jsc) and fill factor (FF), the reduction in the Jsc and FF of the device is most likely to be due to the formation of the charge transfer complex, deep traps and destruction of the-conjugated system in the degraded P3HT:PCBM device. The exposure to oxygen and photo-oxidation lead to the emergence of these factors of the device performance degradation. Keywords: Degradation; Performance; Solar cells; P3HT: PCBM
