Polymer Solar Cell Weight

The molecular weight m n of donor polymers plays a critical role in determining the photovoltaic properties of all polymer solar cells all pscs despite m n of donor polymers has pronounced effects on microstructure morphology photovoltaic performance and stability.

Polymer solar cell weight.

The commercially available pm6 as donor materials are used widely in highly efficient nonfullerene polymer solar cells pscs. Here we revealed that the p i n structure can outperform the bhj ones with a nearly 50 efficiency improvement. As polymer solar cells were not available in marketable forms until 2009 when konarka technologies introduced the first low performing polymer solar panels 21 numerous application ideas have been formulated and a few of these tested in perspective polymer solar cells possess the potential to be applied within consumer electronics developing world applications leisure military and. Substantial research efforts have been devoted into the psc field and its record efficiency has reached 9 2 chen et al 2009.

The influence of the number average molecular weight m n on the blend film morphology and photovoltaic performance of all polymer solar cells apscs fabricated with the donor polymer poly 5 2 hexyldodecyl 1 3 thieno 3 4 c pyrrole 4 6 dione alt 5 5 2 5 bis 3 dodecylthiophen 2 yl thiophene ptpd3t and acceptor polymer poly n n bis 2 octyldodecyl naphthalene 1 4 5 8 bis. Organic solar cells with excellent device performance and stability are essential for both academic and industrial purposes. All polymer organic solar cells offer exceptional stability.

Cohesive values ranged from 0 5 to 17 j m 2 following the general trend of greater cohesion with increasing molecular weight. Polymer solar cell psc is a promising candidate to address the cost issue of current si based photovoltaics because of its scalable and low cost manufacturing processes. These organic semiconductors should have certain band energy e g between the homo and lumo higher. In this work we show that the molecular weight rr p3ht in organic solar cells can also significantly change the internal cohesion of the photoactive layer using micromechanical testing techniques.

Solar cells usually called photovoltaic cells are devices that convert a flux of photons such as sunlight into an electric current. Similar to inorganic solar cells polymer solar cells consist of active layers formed by organic semiconductors that are responsible for absorption of photons. Unfortunately the use of bulk heterojunction bhj structure has the intrinsic challenge to control the side chain entanglement and backbone orientation to achieve sophisticated phase separation in all polymer blends.
