the best solution is that develop solar energy adequately. Polymer solar cells have been researched for over 20 years
the efficiency have overcome 10%。review the history and theory of polymer solar cells
the structure and materials are important factors for polymer solar cells
especially donor. From PPVs to PCDTBT
TTBDT
BDTTPD
the efficiency of solar cells increase quickly as the new donor material was used in polymer solar cells. It's important for putting into using that researching new donor material as the theory have be studied in a deep-going way and the technology mature.
