“…In general, the construction of composite materials relies on the high σ or high S advantage of each component to overcome their respective defects to achieve the improvement of PF . 6 This means that the introduction of CQDs can effectively improve the TE performances of PEDOT:PSS under light illumination, rather than through a compromise. Additionally, carrier concentration ( n ) and mobility ( μ ) were evaluated by the Hall effect measurement for the as-fabricated films.…”

“…When the black silicon light absorber was assembled with thermoelectric modules for photo‐thermoelectric generation, it could achieve a steady voltage of ≈64 mV (Figure 7f) under AM 1.5 G illumination, which showed a performance rise rate of 28% compared with the former work. To further simplify the photo‐thermoelectric device, Liu and his colleagues [ 118 ] integrated the light absorber with thermoelectric material into one device for photo‐thermoelectric power generation. As‐prepared poly (3,4‐ethylenedioxythiophene): poly(styrenesulfonate)/Te nanowires (PEDOT: PSS/Te NW) can be seen in Figure 7g.…”

of monolithic silicon/perovskite solar cell has achieved over 29%. [13,14] Alternatively, photothermal conversion is another way to utilize solar energy and has drawn dramatically increasing attention due to the easily achievable large conversion efficiency (usually larger than 50%) for the applications in thermal catalysis, [15][16][17][18] water evaporation and desalination, [19][20][21][22][23][24][25][26][27] bacterial killing, [28] as well as thermal-responsive sensors. [29][30][31] Photothermal conversion of solar energy refer that solar energy is first converted into heat and then heat energy is utilized to achieve the desired destinations, [15,16,28,[31][32][33][34] such as water purification, desalination, electric power generation, catalysis conversion, bacterial killing, and actuators. Thus, photothermal conversions of solar energy can be supplementary to PV-based technology in solar energy conversion and are deemed to be extremely important to clean energy production. [19,35,36] Very recently, photothermal-derived applications have attracted many researchers' interests and great efforts have been taken to expand the application fields and increase the conversion efficiency based on solar energy conversion. [29,[37][38][39][40][41][42][43][44] Among all the applications, photothermal water evaporation for desalination and water purification has attracted the most attention, owning that freshwater can be directly produced by only using solar energy and it can address the freshwater shortage challenge for many countries. [27,32,33,[45][46][47][48][49][50][51][52][53] However, the research focusing on other applications has attracted less attention than photothermal water evaporation, which should also be taken equally important attention for making the most of solar energy. For example, photothermal catalysis for H 2 generation and CO 2 reduction can be applied to convert solar energy into chemical energy under high concentrated solar intensity, but the efforts are still far from enough. Although photothermal electric power generation can show a solar-to-electricity conversion efficiency exceeding 7% under 38 Sun, [54] its conversion efficiency remains very low under low concentration solar intensity, such as 1 Sun or ambient conditions. Thus, the tradeoff between efficiency, costs, and practicality should be considered in future works. In addition, photothermal bacterial killing technology has proved that it can be efficiently used for killing bacteria under solar light illumination, [28] but whether it can be applied for human or animal wound treatment still needs to be discussed. Furthermore, solar energy can also cause thermally sensitive objects to reversibly change the physical properties for Solar energy is a green, sustainable, and de facto inexhaustible energy source for mankind. The conversion of solar energy into other forms of energy has attracted extensive research interest due to climate change and the energy crisis. Among all the solar energy conversion technologies, photothermal conversio...

“…The first type is so-called homogeneous synchronous PTEGs, in which the photothermal (PT) and TE conversions can be performed almost simultaneously, since the heat required for the TE conversion comes from the PT effects of the TE materials themselves or the introduced PT fillers. The design of this structure can avoid the energy waste caused by the interfacial thermal resistance on the contact surfaces of the PT and TE layers. − For example, Jin et al wrapped polypyrrole (PPy) on helical carbon nanotubes to improve the PT conversion capability of PPy and thus optimize its photo-thermoelectric property, and eventually, the PTEGs constructed with this composite have fast response and excellent output stability, making them possible to be applied to delayed control systems . However, the output performance of such PTEGs is always poor because few materials have both excellent PT and TE properties, and the introduction of fillers with excellent PT properties can enhance the PT conversion capacity of composite materials to some extent, but at the same time, their poor TE properties will affect the overall TE conversion capacity of the composites.…”

The enthusiasm for environmental energy harvesting has triggered a boom in research on photo-thermoelectric generators (PTEGs), and the relevant applications are mainly focused on self-energy supply sensors owing to the limitations of their output performances. For this purpose, high-output hierarchical heterogeneous PTEGs were constructed by assembling separately optimized thermoelectric (TE) and photothermal (PT) layers. The pressure and temperature conditions of Ag2Se films during the pressing process were first explored, and the sample with the optimal performance and least defects was selected as the TE layer. At the same time, different morphologies of polypyrrole (PPy) PT layers were electrochemically synthesized. It is found that the three-dimensional structure of Bushy-PPy could effectively improve the light absorption and thus enhance the PT conversion performance. The final assembled PTEG can produce an output voltage of −9.03 mV and an output power of 3.53 μW under the irradiation of a near-infrared light source of 300 mW cm–2 without a cooling source, and it can also achieve considerable output power under visible light irradiation of different intensities. Combining its high retentions of electrical conductivity (99%) and output performance (97%) after 1000 bending-tension cycles, it is proven to be a promising next-generation wearable flexible energy harvesting device.
