SOME GENERAL CONCEPTS OF ORGANIC PHOTOVOLTAIC SOLAR CELLS - A POTENTIAL CLEAN ENERGY FOR FUTURE

Abstract

Photovoltaic technology is the technique in which the sunlight is converted directly
into electricity. This technique is considered as one of the most effective ways to address
global energy crisis using a renewable resource. While the high cost production and
environmental issues reduced the using of inorganic solar cells in life; low-cost, low
energy budgets, solution processing, flexible solar cells, are the keywords associated with
organic solar cells, led to improve the attention of scientists to this area. The power
conversion efficiencies of organic photovoltaics now reached the record of 11.7% for
organic solar cell used polymer and fullerene derivative in a bulk - heterojunction
(reported by H. Yan’s group), and 13.2% for an organic photovoltaics multi-junction cell
(reported by Heliatek R&D teams at Dresden, Germany). However, this research area is
quiet young in Vietnam. In this paper, we would like to briefly introduce to organic
photovoltaic regarding to history, principle and the main strategies of this technique. This
information may be useful for research in organic solar cells in Vietnam.
