As the planet warms, keeping cool without releasing greenhouse gases will be a challenge,
but radiative cooling technology is poised to meet this goal. Hundreds of radiative cooling …

Perovskite solar cells have attracted tremendous research and development activity in
recent years due to their excellent optoelectronic material properties and ease of fabrication …

Indoor testing of solar thermal absorbers requires an artificial light source with controlled
emitted power and uniform illumination over the targeted sample. There are several devices …

The emissivity of two unencapsulated photovoltaic cells has been measured by a direct
radiometric method, between 30 and 50° C, and indirectly at room temperature. The …

Among solar thermal collectors, the evacuated flat panel is emerging as a reference
technology for operation at temperatures as high as 200° C with an increased annual …

Temperature control in solar cells is important as elevated temperature adversely affects
performance and lifetime. In building-integrated photovoltaics (BIPV), the overall energy …

Uniform illumination is a key requirement in different research fields. However, this
requirement is often difficult to achieve when high intensity is required at the same time …

Um die globale Klimaerwärmung aufzuhalten, wurde vorgeschlagen, die Sonne mithilfe
einer oder mehrerer dünner Strukturen abzuschirmen [1]. In dieser Thesis wurde die …

The solar cell is a semiconductor that produces direct electrical energy by conversion solar
energy into electrical energy [1]–[3]. The conversion consists of several stages:(1) light …
