Theoretical analysis of the performance of a diffraction grating back- reflector in infrared-sensitive solar cells
Mario M. Jakas, Francisco Llopis
The increase of cell efficiency resulting from using a diffraction grating as a back reflector is investigated. An enhancement coefficient is introduced as a figure of merit that a…

LC sine-wave oscillators using general-purpose voltage operational-amplifiers
M. M. Jakas, F. Llopis
It has been found that some text-books show LC-oscillators that may not work as assumed. Thus, the typical example showing a LC-oscillator driven by a voltage operational-amplifier…
