“…The quantum efficiency of terrestrial solar cells is fundamentally restricted to approximately 30% due to high reflectivity, i.e., nearly 35% (Diedenhofen et al, 2012;Sheng et al, 2013), albeit higher efficiencies are theoretically and practically achievable with multijunction solar cells (Pakhanov et al, 2018;Geisz et al, 2020). The optical loss due to reflectivity and environmental conditions can be countered through self-cleaning ARCs to achieve the true potential.…”

Titanium(IV) oxide (TiO2, titania) is well-known for its excellent photocatalytic properties, wide bandgap, chemical resistance, and photostability. Nanostructured TiO2 is extensively utilized in various electronic and energy-related applications such as resistive switching memory devices, flat panel displays, photodiodes, solar water-splitting, photocatalysis, and solar cells. This article presents recent advances in the design and nanostructuring of TiO2-containing antireflective self-cleaning coatings for solar cells. In particular, the energy harvesting efficiency of a solar cell is greatly diminished by the surface reflections and deposition of environmental contaminants over time. Nanostructured TiO2 coatings not only minimize reflection through the graded transition of the refractive index but simultaneously improve the device’s ability to self-clean and photocatalytically degrade the pollutants. Thus, novel approaches to achieve higher solar cell efficiency and stability with pristine TiO2 and TiO2-containing nanocomposite coatings are highlighted herein. The results are compared and discussed to emphasize the key research and development shortfalls and a commercialization perspective is considered to guide future research.

“…Разработанные наземные солнечные батареи и энергоустановки нового поколения с концентраторами солнечного излучения [1][2][3][4][5][6][7][8][9] открывают перспективы существенного снижения стоимости получаемой электроэнергии за счет снижения площади солнечных элементов пропорционально кратности концентрирования солнечного излучения и увеличения удельной (с единицы площади) мощности батарей. Прецизионное отслеживание положения Солнца и улучшенная температурная стабильность КПД приводит к дополнительному увеличению на 30-40 % количества электроэнергии, вырабатываемой концентраторными солнечными фотоэнергоустановками, по сравнению с традиционными батареями без систем слежения.…”

Photovoltaic conversion of the solar energy is the most prospective direction of the renewable power engineering. Solar arrays ensure power supply of spacecrafts and are gaining increasingly more application on the Earth. In the majority of developed countries, laws on state support of the green power engineering assisted in a substantial increase of power of the solar photovoltaic systems have been adopted. The main barrier to increasing the terrestrial solar photovoltaics development rates is a relatively high cost of the solar electric power. The ways for reducing the cost are the rise of the efficiency of power systems and the reduction of the material consumption for arrays based on multijunction solar cells. Results of multijunction solar cells and modules developments for space and terrestrial solar arrays are discussed in the article. In the last years, a significant experience on creation of multijunction solar cells was accumulated. Cascade solar cells and solar photovoltaic installations on their base with sunlight concentrators have been developed. At present, the terrestrial cascade solar cell efficiency exceeds 45%, which is substantially higher than that in conventional Si and thin-film solar arrays. The cascade solar cell efficiency increase has been achieved at the expense of splitting the sunlight spectrum into several intervals by the solar cell semiconductor structure fulfilling more effective photon energy conversion of each of these intervals in a definite parts of this structure. It is shown that multijunction solar cells provide the highest efficiency and they are the basic components of space arrays. Multijunction solar cells provide the highest conversion efficiency of concentrated sunlight as well. It opens prospects for decreasing the solar cell area and cost proportionally to the sunlight concentration. Developed concentrated photovoltaic installations are promising for wide applications in the high scale terrestrial solar photovoltaic energetics.

“…GaInP/GaInAs/Ge lattice-matched triple-junction solar cells have been widely used in space photovoltaic applications and have attained the highest efficiency over 30% [1,2]. The heavy radiation bombardment with various energetic particles in a space environment will inevitably damage the solar cells and result in additional non-radiative recombination centers, which reduces the minority carrier diffusion length and leads to degradation of the solar cell efficiency [3].…”

This paper studies the radiation resistance for GaInP/GaInAs/Ge triple-junction space solar cells with a GaInP back-surface field (BSF) in the GaInAs middle subcell compared with those with an AlGaAs BSF. The results show that the initial electrical performance is almost the same for both of them. However, the radiation resistance of the GaInP BSF cell was improved. After irradiation by 1 MeV electron beam with a cumulative dose of 1015 e/cm2, the Jsc declined by 4.73% and 6.61% for the GaInP BSF cell and the AlGaAs BSF cell, respectively; the efficiency degradation was 13.64% and 14.61% for the GaInP BSF cell and the AlGaAs BSF cell, respectively, leading to a reduced degradation level of 6%. The mechanism for GaInP BSF to improve the radiation resistance of GaInP/GaInAs/Ge triple-junction solar cells is also discussed in this work. Similar results were obtained when irradiation cumulative doses varied from 1 × 1014 e/cm2 to 1 × 1016 e/cm2.
