Investigation of Indoor Stability Testing of Polymer Solar Cell

الملخص EN

We have fabricated organic solar cell of a new low bandgap polymer poly[4,4-bis(2-ethylhexyl)-4H-cyclopenta[2,1-b:3,4-b′]dithiophene-2,6-diyl-alt-4,7-bis(2-thienyl)-2,1,3-benzothiadiazole-5′,5′′-diyl] (PCPDTTBTT).

We have investigated for the first time the stability tests, ISOS-L-1 and ISOS-D-3, of PCPDTTBTT solar cells.

Thermal annealing of PCPDTTBTT solar cells at 80°C brought about an improvement of photocurrent generation, stability, and efficiency of the solar cells.

T80 value of PCPDTTBTT solar cell is about 150 hours which is close to P3HT (235 h).

PCPDTTBTT is very promising polymer for both polymer solar cell efficiency and stability.
