In this paper we explore the possibilities of implementation of triangular thin-film photovoltaic modules. A concept of "balanced strip pairs" based on a coupling of photovoltaic strips of different lengths is proposed. This concept provides a uniformity of current output of all individual cells, and could be easily implemented with widely used monolithic integration with some additional wiring. One of the additional advantages of this concept is a freedom in designing the module's output voltage. As a reference to the proposed strategy a division of the triangular photovoltaic module into trapezoid cells with the equal area is presented. (C) 2015 Elsevier Ltd. All rights reserved.
