Concerning a novel mathematical approach to the solar cell junction ideality factor estimation

The problem of finding an analytical solution of the solar cell junction ideality factor n is studied in some detail, by the Special Trans Functions Theory (STFT). The advanced STFT iterative method just as the structure of the theoretical derivation is presented, while proofs and numerical results confirm the validity and base principle of the STFT. In addition, the obtained results are compared with the calculated values of other methods for alternative proving its significance. Undoubtedly, the proposed novel STFT exact analytical approach implies qualitative improvement of the conventional analytical and numerical methods.
