“…Up to now, not many attempts have been made to develop such a transparent photovoltaic device. Semi‐transparent solar cells have been produced by Lim et al () from a‐Si:H and a‐SiGe:H that show low average transmittance values in the visible range. Warasawa et al presented semiconductor devices based on RF‐sputtered NiO thin films that exhibited weak photovoltaic activity but high transparency in the visible spectral range ().…”

Semi‐transparent pn‐heterojunctions were fabricated from pulsed laser deposited (PLD) n‐type ZnO and DC magnetron sputtered p‐type NiO, working as UV‐active solar cells. The complete cell stack has an average transmission of 46% in the visible spectral range and an optical absorption edge at 380 nm. The diodes exhibit high current rectification of up to eight orders of magnitude at ±2 V. Upon illumination with a solar simulator, the devices show photovoltaic activity with open‐circuit voltages of up to 520 mV, short‐circuit current densities of 0.5 mAcm2, and a maximum external quantum efficiency of 55%. However, we observed rather low fill factors of the current–voltage characteristics of around 40%, resulting in total power conversion efficiencies of around 0.1% and efficiencies in the UV range of 3.1%. To identify possible loss mechanisms, the voltage‐dependent efficiency of carrier collection was calculated. The data were fitted using a model that considers recombination losses at the NiO/ZnO interface as well as within the electric field region, yielding a high hole interface recombination velocity of 1×105cm s−1. We conclude that the carrier collection efficiency is strongly deteriorated by recombination losses at the NiO/ZnO interface, causing a strong bending of the jV characteristics under illumination and thereby low fill factors.

“…Novel functional solar cells that are flexible, transparent, and suitable for building-integrated photovoltaic (BIPV) applications have attracted much recent interest in the solar industry [1][2][3][4]. It is forecasted that the share of transparent solar cells could be further increased in the BIPV market because transparent solar cells can be easily used in windows of buildings.…”

We showed that thin n-type CuO x films can be deposited by radio-frequency magnetron reactive sputtering and demonstrated the fabrication of n-CuO x /intrinsic hydrogenated amorphous silicon (i-a-Si:H) heterojunction solar cells (HSCs) for the first time. A highly n-doped hydrogenated microcrystalline Si (n-μc-Si:H) layer was introduced as a depletionassisting layer to further improve the performance of n-CuO x /i-a-Si:H HSCs. An analysis of the external quantum efficiency and energy-band diagram showed that the thin depletion-assisting layer helped establish sufficient depletion and increased the built-in potential in the n-CuO x layer. The fabricated HSC exhibited a high open-circuit voltage of 0.715 V and an efficiency of 4.79%.

“…Lim et al [ 122 ] studied the use of thin films, hydrogenated, amorphous silicon, and silicon-germanium cells to use as semi-transparent solar cells. The fabrication technique used for that purpose was radiofrequency (rf)-plasma-enhanced chemical vapor deposition working at 250 °C and 1.6 Pa. Their results proved that, related to transparency and efficiency of the cell, the transparent conductive oxides thickness should be superior to 300 nm.…”

Inorganic glass is a transparent functional material and one of the few materials that keeps leading innovation. In the last decades, inorganic glass was integrated into opto-electronic devices such as optical fibers, semiconductors, solar cells, transparent photovoltaic devices, or photonic crystals and in smart materials applications such as environmental, pharmaceutical, and medical sensors, reinforcing its influence as an essential material and providing potential growth opportunities for the market. Moreover, inorganic glass is the only material that is 100% recyclable and can incorporate other industrial offscourings and/or residues to be used as raw materials. Over time, inorganic glass experienced an extensive range of fabrication techniques, from traditional melting-quenching (with an immense diversity of protocols) to chemical vapor deposition (CVD), physical vapor deposition (PVD), and wet chemistry routes as sol-gel and solvothermal processes. Additive manufacturing (AM) was recently added to the list. Bulks (3D), thin/thick films (2D), flexible glass (2D), powders (2D), fibers (1D), and nanoparticles (NPs) (0D) are examples of possible inorganic glass architectures able to integrate smart materials and opto-electronic devices, leading to added-value products in a wide range of markets. In this review, selected examples of inorganic glasses in areas such as: (i) magnetic glass materials, (ii) solar cells and transparent photovoltaic devices, (iii) photonic crystal, and (iv) smart materials are presented and discussed.
