We present a physics-based semi-analytical model of bulk heterojunction (BHJ) organic solar cell (OSC) for predicting the electrical characteristics of the device, taking into account the space dependency of generation rate profiles. The model enable

We present an analytical model for bulk heterojunction organic solar cells on the basis of an empirical expression of space dependent carrier generation rate. By developing the empirical formula of the carrier generation rate and successfully incorpo

When vertically aligned carbon nanotube arrays (CNT forests) are heated by optical, electrical, or any other means, heat confinement in the lateral directions (i.e. perpendicular to the CNTs’ axes), which stems from the anisotropic structure of the

Carbon nanotube forests have great potential as efficient thermionic electron emitters due to a highly localized optical heating effect (“Heat Trap”). In past experiments, we observed a rapid decay in the emission current. In this work, we demons
We present a model to show that heat propagation away from a local source depends strongly on dimensionality, leading to dramatic localization in low-dimensional systems. An example of such a system is a carbon nanotube array. We further show that th

We present an optoelectronic analytical model for bulk heterojunction organic solar cells. Incorporating optical transfer matrix theory in the electrical transport equations, we combine optical and electrical phenomena. This leads us to a single unif

We present an analytical model for bulk heterojunction organic solar cells incorporating the physics of recombination in the transport equations. Monomolecular recombination process is considered to be the dominant mechanism and treated explicitly. T

Carbon nanotube (CNT) forests show great promise for efficient heat-to-electricity conversion due to their ability to confine heat to a localized area. In this work, we investigate CNT forest density as a possible factor in further optimizing their e

A compact analytical model of minority carrier -concentration is presented for an exponentially-doped quasi-neutral region of Silicon solar cell. It is an iteration-free and integral-free mathematical expression that addresses the non-uniformity in d
