Abstract
In the present invention a new solar photovoltaic module is proposed comprising: a silicon based photovoltaic element; an intermediate layer deposited on said photovoltaic element to the incident light side; an interference filter deposited on the incident light side of said intermediate layer; a front element disposed on the incident light side of said interference filter. Said intermediate layer has a transparency of at least 90% for infrared light between 780 nm and 1200 nm and said interference filter is corrugated and composed of a multilayer comprising a plurality of dielectric layers designed to transmit at least 75% of the total incident solar infrared light between 780 nm and 1200 nm, and to reflect and diffuse incident visible solar light such that the perceived color of said reflected and diffused visible light by any observer positioned anywhere to the incident light side of said solar photovoltaic module and looking towards the front element of said solar photovoltaic module is defined by a Y10 tristimulus value not lower than 50 defined by an x value of 0.20 to 0.45 and a y value of 0.20 to 0.45 in a chromaticity diagram of a CIE 1964 Yxy color system using a white li…
