Global prediction of the energy yields for hybrid perovskite/Si tandem and Si heterojunction single solar modules

Abstract

A strong expectation exists for a two-terminal hybrid perovskite/silicon tandem solar cell for generating substantially higher output power. Nevertheless, a high tandem cell efficiency under the standard condition does not guarantee high power generation in outdoor environment due to the requirement of current matching in a tandem device. Here, we predict the global energy yields of hybrid perovskite/Si tandem and Si heterojunction single modules by establishing a new rigorous self-consistent model that performs full device simulations incorporating all fundamental time-varying parameters affecting the module power output. In particular, the temperature dependences of the optical and electrical characteristics are modeled explicitly and reliable model parameters are extracted from an industry-compatible Si heterojunction single cell (23.27% efficiency with a 120 μm wafer thickness), whereas ideal cell characteris-

Energy Yield Prediction of Bifacial Perovskite/Silicon Tandem Photovoltaic Modules

“…This is consistent with the previous report which states that the lowest value of FF is located at the current matching point. [ 20,29 ] For bifacial tandem modules with other E g_PVK s, one also sees an increasing FF with rising current mismatch after increasing albedo (see Figure S9, Supporting Information).…”

“…[16][17][18][19] After that, the climate-dependent EY of tandem modules on a global scale was investigated, which demonstrated that the monofacial tandem modules are more advantageous than SHJ modules in terms of EY. [20] Assuming comparable lifetime of PVK materials with that of c-Si cells, the LCOE of high-efficiency PVK/c-Si tandem modules is predicted more advantageous than that of single-junction c-Si modules. [21] In the previous work, the EY and related characteristics were mainly conducted for monofacial PV modules in which SHJ was typically used as the bottom cell.…”

“…[21] In the previous work, the EY and related characteristics were mainly conducted for monofacial PV modules in which SHJ was typically used as the bottom cell. [15][16][17]20,22,23] However, SHJ solar cells naturally possess bifacial light-receiving feature that can effectively absorb diffuse light reflected by the ground (called albedo) and by the atmosphere and surroundings. This bifaciality will result in an increase in the EY of about 25-30%.…”

“…Thus, the dependences of η SC and η STC on T cell are essential for evaluation of annual production. 31,45,46) Therefore, the explicit T cell dependence and T cell -dependent E g (dE dT g cell = 0.31 meV K -1 for PVK 47) and −0.27 meV K -1 for Si 48) ) in Eqs.
