Sažetak
Chalcopyrite semiconductors are promising absorber materials for thin film solar cells applications due to their high absorption coefficient. Also they are the only thin-film materials with several years of outdoor exposure that showed no deterioration in performance. The most important compound in CuInSe2 (commonly abbreviated as CIS) with a band gap of 1.0 eV. By alloying CIS with other chalcopyrite, e.g. CuGaSe2 (band gap 1.7 eV) or CuInSe2 (band gap 1.5 eV), it is possible to tailor band gap and cell voltage corresponding to requirements of module fabrication. CIS and related compound are rated as leading materials in development of economical photovoltaic energy conversion. This cost-effectiveness, and due to high conversion efficiencies exceeding 17% (Siemens Solar Inc., 9/98) and potential low cost of thin film technology. The internal structure of polycrystalline thin film solar cells is much more complicated than that of crystalline cells. Many authors used some known or developed a new simulation programs, numerical modelling or calculating methods, which can realistically simulate various characteristics of CIS thin film solar cells. We compare some of them: SCAPS-1D program which can realistically simulate all cell characteristics and to calculate the module efficiency (1), SGS (special quasi random structures) (2). First-Principles method (3), MPB (MIT Photonic-Band package) ($) and ADEPT (A Device Emulation Program and Tool)(5) with experimental results and find that there is a good correlation between theory and practical experiment. Prognosis for commercial, low-cost, efficient thin-film photovoltaic modules based on CIS solar cells are very good, and the production is expected to start within next a few years.
