High-efficiency compound solar cells

What are the benefits of compound solar cells?

Compound solar cells’ benefits include light weight, high efficiency, and the ability to conform to curved surfaces. Sharp has already implemented widespread usage of compound solar cells on artificial satellites* 1 but they also hold high hope for use in aerospace, EVs, and other applications in the field of mobility.

Which solar cell has the highest conversion efficiency?

At present, the highest conversion efficiency of solar cells is 47.1% achieved by six-junction inverted metamorphic (6 J IMM) solar cells under 143 suns . The high-efficiency III-V triple-junction cells are also becoming the mainstream of space solar cells.

Which solar cells have the highest potential efficiencies?

Recently, highest efficiencies of 39.1% under 1-sun and 47.2% under 144-suns concentration have been demonstrated with 6-junction solar cells. The 3-junction and 6-junction solar cells potential efficiencies of 42% and 46% under 1-sun, respectively.

Are III-V compound solar cells useful for multi-junction solar cells?

The III-V compound solar cells represented by GaAs solar cells have contributed as space and concentrator solar cells and are important as sub-cells for multi-junction solar cells. This chapter reviews progress in III-V compound single-junction solar cells such as GaAs, InP, AlGaAs and InGaP cells.

Which solar cells have the highest recombination and resistance losses?

Especially, GaAs solar cells have shown 29.1% under 1-sun, highest ever reported for single-junction solar cells. In addition, analytical results for non-radiative recombination and resistance losses in III-V compound solar cells are shown by considering fundamentals for major losses in III-V compound materials and solar cells.

What are the efficiencies of solar cells?

As a result of research and development, high-efficiencies [1, 2] have been 24.2% for InP, 16.6% for AlGaAs, and 22% for InGaP solar cells. Figure 1 shows cells along with their extrapolations . characteristic development time. Fitting of the curve was done with three parame- ters which are given in Table 1.
