<p>Disclosed is a photovoltaic device (100) adapted for receiving incident light (110). The device (100) includes a plurality of photovoltaic cells each comprising a first end and a second end, the first ends nearer the incident light (110). Each cell includes a first conductive layer (120), a photoactive layer (130) adjacent the first conductive layer (120), a second conductive layer (14) adjacent the photoactive layer (130) and a substrate (15) adjacent one of the first and second conductive layers. The substrate (150) comprises a channel therethrough and wherein the photovoltaic cells are substantially stacked in the direction of incident light (110). The device (100) also includes a reflective surface adjacent the second ends and a lensing system disposed between the incident light (110) and the first ends. The plurality of photo voltaic cells are tilted from a vertical axis defined by the incident light (110).</p> |
