摘要： A solar cell structure is provided. The solar cell structure includes a substrate, a front transparent conductive oxide (TCO) layer, a primary light absorbing layer, a back TCO layer, and a metal thin film layer stacked from bottom to top. The back TCO layer includes a coarse upper surface. Or alternatively, the solar cell structure includes a substrate, a front TCO layer, at least one first light absorbing layer, at least one interface layer, at least one second light absorbing layer, a back TCO layer, and a metal thin film layer stacked from bottom to top. The interface layer includes a coarse upper surface. Because of the coarse upper surface of the back TCO layer or the interface layer, the light is facilitated for further scattering, so that the light absorbing efficiency can be improved, thus improving the efficiency of the solar cell.

摘要： A thin film solar cell having opaque and highly reflective particles and a manufacturing method thereof are provided. The thin film solar cell at least includes a substrate, a front electrode layer, a first photo-electric converting layer, a second photo-electric converting layer, and a back electrode layer. The particles are made of a highly conductive material, disposed between the first photo-electric converting layer and the second photo-electric converting layer, and distributed in a discontinuous manner. When an incident light strikes the surfaces of the particles, the incident light is reflected within the first photo-electric converting layer and the second photo-electric converting layer so as to increase the propagation path of the incident light through the first photo-electric converting layer and the second photo-electric converting layer.
