“…In the context of this perspective, the integration of NAA–PCs into solar cell systems has been explored to break through some of these technological bottlenecks, harnessing the unique geometric, optical, thermal, and electrically insulative properties of NAA to maximize photon‐to‐electron conversion rates in solar cell systems. In particular, NAA‐based Fabry–Pérot interferometers (NAA–FPIs) have been integrated into PV cells as scaffolds for PV materials, [ 184,185 ] radiative coolers, [ 186 ] electrodes, [ 184,187 ] and antireflective coatings.

Nanoporous anodic alumina (NAA) fabricated by anodization of aluminum is a versatile platform material with tailorable geometric, optical, and chemical features for specific light‐based technologies and applications. Recent advances in anodization technology have enabled a new generation of NAA‐based photonic crystals (PCs)—periodic dielectric nanoporous structures that selectively allow, forbid, and confine the flow of incoming electromagnetic waves of specific wavelengths across their structure. NAA–PCs provide exciting new opportunities to engineer light–matter interactions with versatility across the broad spectrum, from UV to IR. But despite these fundamental advances, demonstrations of sunlight‐harvesting technologies based on NAA–PCs are still limited. Herein, an up‐to‐date summary of recent advances in NAA–PC technology is provided, and proof‐of‐concept demonstrations and future pathways to propel this versatile platform material across sunlight‐harvesting technologies such as photocatalysis, photoelectrocatalysis, photothermal energy conversion, and solar cells are discussed.

Compared with monofacial photovoltaics, bifacial photovoltaic modules can absorb the irradiance on both sides, thereby obtaining more electricity revenue, which can meet more demands. In order to further improve the electrical efficiency of bifacial photovoltaics, this paper proposes a bifacial photovoltaic module with adjustable inclination for simulation and experimental research, which can be well combined with architecture. Under the conditions of different inclination, orientations and heights, the output performance of the bifacial photovoltaic module is analyzed. Under the best inclination, the annual electrical energy of bifacial photovoltaic is about 9.4% higher than that of monofacial photovoltaics. When the spacing between the bifacial photovoltaic and the wall is 1-1.5 times the size of the photovoltaic, the electrical energy will increase the most. Considering the influence of wall color on bifacial photovoltaic performance, the photovoltaic electrical energy under the white wall can reach up to 35% higher than that with respect to the concrete color (dark grey).

With the great increase in installation, photovoltaics will develop as the main power supply source for the world shortly. However, the actual power generation and lifetime of photovoltaics are greatly compromised by the high working temperature under outdoor operation. In this review, the recent advances of four promising passive photovoltaic cooling methods are summarized with the aim to uncover their working principles, cooling performance, and application potential in photovoltaic devices. For radiative cooling, light management strategies with ultraviolet‐photon downshift and sub‐bandgap reflection are discussed in detail to reveal their great potential in reducing photovoltaic working temperature and enhancing power generation. Subsequently, the great cooling benefits of passive evaporative cooling are underlined in terms of its superior cooling power and temperature drop of photovoltaic devices. Moreover, the promising integrated cooling strategy is further highlighted due to its great potential in enhancing electricity production and fresh water supply. Most crucially, the remaining challenges and the authors'r insights are presented to advance the commercial applications of passive cooling methods in photovoltaics.
