For this end, a low refractive index dielectric is typically inserted under the rear metal and an electrical contact is obtained locally through the dielectric.

Herein, a simple approach is proposed in which commercially available, low-cost SiO₂ nanoparticles (NPs) are spin coated as rear reflectors on pyramid-textured Si, leaving the pyramid tips locally exposed for direct contact by an electrode without additional patterning. In Si heterojunction solar cells, complementing a 40 nm-thick indium tin oxide (ITO) layer with the SiO₂-NPs yields a gain of 0.3 mA cm⁻² in short-circuit current density compared to that obtained with a bare, 100 nm-thick ITO layer.

This article reports the development of wide-bandgap, inorganic-based TPV devices integrating ultrathin hydrogenated amorphous silicon (a-Si:H) as a transparent absorber, with carrier selective contacts and transparent electrodes. The article analyzes how absorber thickness influences the electrical, optical, and aesthetic performance of devices, evaluating key parameters in TPV such as light utilization efficiency (LUE), average photopic transmittance (APT), color rendering index (CRI), and electrical properties such as power conversion efficiency (PCE).

This approach results in PCE ranging from 1.7% with an APT of 60% to a PCE of 4.1% with an APT of 28%, yielding LUE values between 0.9% and 1.3%. Device characterization encompasses optical spectrophotometry, J–V measurements under standard test conditions, spectral response analysis, and variable illumination measurements (VIM).

In this research, it is suggested that filtering out sunlight is mandatory, although it overlaps with the solar cell luminescence emission range. Moreover, image processing is required for daylight images to enhance the signal-to-noise ratio (SNR) and ensure optimal image quality under varying solar conditions.

In the results, it is indicated that, for the PV modules studied, filters with a transmission bandwidth of 50–300 nm around the EL spectrum peak provide a sufficiently high SNR and image quality for fault detection and quantification comparable to indoor-quality images.
