      abstract     = {Cellulose substrates for PV applications present a fibrous
                      surface texture that is not suitable for the uniform
                      deposition of thin-film solar cells causing poor device
                      performance. However, uniform thin-film deposition and
                      efficient light management for solar cells can be achieved
                      on cellulose substrates by transferring well-known surface
                      textures that provide an adequate surface for thin film
                      solar cell deposition and also, provide light scattering
                      properties into the cellulose surface. In this work, we
                      study the properties of crater-like textures transferred
                      onto cellulose substrates by nanoimprint lithography and the
                      corresponding effect on the J–V and EQE characteristics of
                      amorphous silicon thin-film solar cells. The prototype solar
                      cells are deposited on cellulose substrates and the results
                      are compared with the results of such solar cells deposited
                      on flat glass substrates. The results show that the J–V
                      characteristics of solar cells deposited on planar as well
                      as textured glass substrates are well reproduced. Due to the
                      process routine, the solar cells on the cellulose substrate
                      with nanoimprinted textures show an increase in the short
                      circuit current density and power conversion efficiency over
                      previous results in our laboratory.},
