The present disclosure belongs to the technical field of photovoltaic modules, and relates to an encapsulation structure of perovskite solar cell module and an encapsulation method of encapsulation structure of perovskite solar cell module. The encapsulation structure includes a transparent conductive substrate, a perovskite solar cell module and an encapsulation component, which are sequentially stacked; the encapsulation component includes an encapsulation layer and a glass cover plate disposed thereon; and the encapsulation layer has a structure in which at least one polyolefin thermoplastic elastomer layer and at least one inorganic layer are alternately stacked. The polyolefin thermoplastic elastomer layer and the inorganic layer have a better complementary effect and excellent adhesion property, so that a perovskite cell can be better encapsulated by the encapsulation component and thus has a very low water vapor transmission efficiency, thereby the corrosion of water and/or oxygen to the perovskite cell can be reduced; and meanwhile the perovskite cell has relatively high tolerance to potential-induced attenuation, and thus has a relatively long service life and relatively good stability, therefore the perovskite cell can be applied to a high-humidity environment such as sleep, seasides, ponds, etc.

The present disclosure is generally related to photonic crystals, for example, for thermophotovoltaic power generation or other applications. Some aspects are directed to articles having multiple substrates that are used to contain vacuum or interior regions, for example, containing a photonic crystal. These articles may be heated in some embodiments by substantial amounts, without allowing leaks to occur into such regions. For instance, in some cases, the substrates may have similar coefficients of thermal expansion, which may expand in a substantially uniform manner to maintain physical contact without leaking. In some cases, a substrate may comprise sapphire and/or another IR-transparent material, e.g., to transmit emissions from the photonic crystal. In some cases, a substrate may comprise niobium and/or another metal, which may exhibit similar thermal expansion as sapphire. Other aspects are generally directed to methods of making or using the articles, kits including such articles, or the like.

The present disclosure generally relates to photonic crystals, for example, for thermophotovoltaic power generation, or other applications, and to systems and methods for bonding metals or other materials together. Certain aspects are generally drawn to tantalum or other refractory metals that are bonded to Inconel or another metal superalloy. The tantalum or other refractory metals may be used as a photonic crystal in certain instances, e.g., to produce emissions when heated. In other aspects, other materials can also be used. In some cases, there may be substantially no gaps present between the materials, which may facilitate heat transfer between the materials. In some embodiments, the materials can be forced to or bonded together by heating the materials such that one material is unable to expand without exerting a force on the other material. For example, in a structure having a substantially circular cross-section, a first, inner portion comprising Inconel or another metal superalloy may be heated to force it against a second, outer portion comprising tantalum or another refractory metal, for example, because the first portion may expand faster than the second portion. This may create an interface that is substantially free of gaps. Still other aspects are generally directed to methods of using such materials, devices or kits including such structures or materials, or the like.
